Who Uses Chem-Crete?

bg
Highway Departments

Highway Agencies, worldwide, face challenges related to maintaining and preserving the massive investment in infrastructure and providing a safe and efficient transportation network. Chem-Crete products, both surface applied and inter-blended with the Portland cement concrete (PCC) can provide cost effective solutions to the most common problems including resistance to deicing salts, freeze/thaw damage, alkali-silica reactivity and many others.

bg
Cities and Municipalities

Cities and municipalities are typically responsible for a wide variety of infrastructure types including water and wastewater treatment facilities, structures, monuments, streets and roads. The Chem-Crete’s product line has a solution for many of the recurring problems that consume both time and limited resources common to most local government agencies. For example, Chem-Crete Pavix CCC-100 can be applied to existing slabs-on-grade (concrete streets, sidewalks, parking areas and others) to greatly improve performance and longevity, particularly in freeze/thaw environments or where deicing salts are used.

bg
Airport Authorities

Airport Authorities, worldwide, operate under very stringent construction and maintenance standards due to safety considerations and to minimize downtime that would impede normal airport operations. Concrete deterioration due to freeze/thaw, application of deicers, alkali-silica reactivity and other mechanisms can greatly affect both safety and operational readiness. Many of these issues can be addressed by application of appropriate Chem-Crete products that make the concrete highly impermeable and thereby minimize moisture and chemical-related damage.

bg
Engineers and Architects

Engineers and Architects are frequently tasked with writing project specifications and selecting appropriate materials. PCC is the most widely used construction material in the world and therefore is used in a variety of applications including highways, airfields, port facilities, buildings and numerous others. Chem-Crete products can be used to increase the longevity and performance of PCC used in the most challenging environments

bg
Contractors and Builders

Contractors are required to conform to both plans and specifications when constructing highways, airfields, parking areas, etc. They are frequently required to warranty their work for extended time periods against non-load related cracking and other forms of concrete deterioration. Chem-Crete has developed number of surface applied and internally mixed products to promote enhanced curing and minimize the influence of water and externally applied chemicals. In addition, specialty Chem-Crete products have been shown to minimize early plastic (drying) shrinkage cracking when used in conjunction with adequate curing thereby providing added insurance against this construction-related defect.

Pavements & Structures Protection

Concrete does not break down overnight. It fails one freeze-thaw cycle, one chloride ion penetration, one hairline crack at a time, until a structure built to be last decades starts showing its age in years. In pavement construction, both concrete pavements and asphalt pavements share similar durability issues and concerns. That’s the problem International Chem-Crete set out to solve nearly 50 years ago, and it still continues to be the problem our Concrete Structures Protection line is designed to conquer. Every road, runway, bridge deck, and parking structure is under constant attack from forces most people never think about, such as deicing salts eating away reinforcing steel, water and vapor working through pores and micro-cracks, and alkali-silica reaction slowly expanding concrete from within. These threats can't be ignored for any structural construction company that is responsible for sustainable structures to be used for 30, 40, or 50 years. It's a budget problem waiting to happen. A proactive pavement preservation strategy pays for itself many times over.

Why Pavement Preservation Beats Repair

There's an old saying in infrastructure management: the best time to protect a pavement is before it needs repair, not after. When cracking, scaling, spalling, or corrosion of the rebar occurs, you are no longer “maintaining”; you are “rebuilding,” and rebuilding costs many times what preservation does. Our pavement preservation treatment and products are specifically designed to get ahead of that curve, penetrating and lining the pore structure of concrete so water, chlorides, and moisture can't do the damage they're designed to do. Three products, three ways to protect:
  • CHEM-CRETE® MCE™: A multi-crystalline permeability reducing admixture (PRA), mixed directly into the fresh concrete batch, that waterproofs the whole concrete matrix from within. Ideal for any structural construction company that wants durability-engineered, sustainable infrastructure from the start rather than added on later. MCE is simply dosed to the concrete mixture as any other admixture.
  • CHEM-CRETE® PAVIX® CCC® 100: A topical treatment that can be used on green and cured concrete alike, blocking pores and lining capillaries against water, moisture, and ice adhesion. Built as a concrete sealer for airport runways, highway pavements, and bridge decks, where reliability under constant traffic and weather stress is non-negotiable.
  • CHEM-CRETE Greenicer: A green deicer and crystalline waterproofing and restoration treatment for concrete pavements. It is used for pavement treatment and bridge deck protection against ice adhesion.
  • CHEM-CRETE ASP®: A silicone-modified asphalt sealer custom-made for asphalt pavements, enhancing pavement durability and extending service life on the asphalt side of a project with the same protect-first approach.

Structural Protection Services Built on Real Chemistry

It’s not just the products that tie this category together, but the way it’s done. International Chem-Crete does not provide one-size-fits-all pavements. We provide structural protection products based on years of laboratory and field-tested chemistry, aimed at the specific mechanisms that actually cause concrete and asphalt failures: chloride ion penetration, freeze-thaw cycling, ASR, biological attack, ice adhesion, and moisture flow through both positive and negative sides of a structure. That distinction matters for :
  • Highway departments managing thousands of lane-miles
  • Municipalities responsible for aging infrastructure
  • Airport authorities where downtime isn't an option
  • Engineers writing specifications that are required to last for years, decades, or even generations.
Whether it is protecting a freshly poured structure or extending the life of an existing structure, this category is designed to be the foundation for pavement preservation programs that actually deliver, resulting in fewer emergency repairs, longer asset life, and lower total cost of ownership. Protecting pavements and structures isn't about putting on a sealer and hoping for the best. It's about understanding the actual deterioration of concrete and asphalt and then engineering a solution that interrupts that deterioration at the point of its origin. That's what nearly five decades of International Chem-Crete research has been built around, and why any structural construction company looking for a long-term pavement preservation partner keeps coming back to this category. FAQs Que : What is the difference between concrete crystalline waterproofing and water-repelling Ans : Crystalline waterproofing is pore-blocking or filling for reducing water permeability through the precipitation of crystals (hygroscopic and/or hydrophilic crystals) within the concrete pores. Water-repelling is just establishing hydrophobicity at the pore surfaces that reduces water absorption under insignificant hydrostatic pressure. Que : What's the difference between a topical treatment and an admixture for pavement protection? Ans : A topical treatment like PAVIX CCC-100 is applied to the surface of green or cured concrete, penetrating and then blocking existing pores and capillaries after placement. The resulting concrete automatically contains a protective density from the very beginning, as an admixture is added to the concrete when it is being mixed, leading to pore blocking for the wall concrete structure. Que : Can these products be used on existing pavements, or only new construction? Ans : MCE is used only in new construction. PAVIX CCC-100 is formulated to work on cured, in-service concrete as well as new pours, making it a practical option for preservation programs on existing highways, bridges, and airport pavements. ASP is applicable to new and existing asphalt pavement. Que : Is asphalt protection different from concrete protection? Ans : Yes. Asphalt and concrete have different chemistry and deteriorate through different mechanisms, which is why CHEM-CRETE ASP® uses a silicone-modified formulation specifically suited to asphalt, separate from the crystalline waterproofing chemistry used on concrete. From a functionality perspective, both pavement durability solutions target pore blocking and water repellency.

Concrete Admixtures and Enhancers

Every strong concrete structure starts long before the pour, in the mix design. Get the chemistry right at that stage, and you're building in strength, density, and water resistance with a concrete durability solution. That's the idea behind International Chem-Crete's Concrete Admixtures and Enhancers line to provide exceptionally durable concrete, built from the inside out. This is very important in pavement construction, and more particularly for pavement durability with 1L cement problems (or PLC concrete problems). For any structural construction company that's watched a "perfectly good" pour crack, spall, or let water through within a few years, the message is simple: the mix matters as much as the placement. Our Integral waterproofing admixture (concrete crystalline admixture) is formulated to provide concrete with the internal resistance it needs to perform for decades, not just pass inspection on day one.

Why the Right Admixture Changes Everything

Not all concrete admixtures have the same purpose, and that's exactly the point. Among concrete admixture companies, International Chem-Crete has spent nearly 50 years focused on one core problem: how do you ensure concrete durability and make concrete inherently resistant to the things that destroy it, such as water intrusion, chloride penetration, alkali-silica reaction, and drying shrinkage, rather than just dealing with the symptoms after the concrete is in place. This focus is reflected in the products that form the core of this category:
  • CHEM-CRETE® MAG-SIL®: A powdered intermixed concrete enhancer that's part of Chem-Crete's dual crystallization family. Incorporated at the batching stage (much like fly ash, slag, or silica fume), MAG-SIL enhances the compressive and flexural strength, increases workability, lowers permeability, reduces ASR potential, and cuts chloride intrusion, all from within the mix itself.
  • CHEM-CRETE® MCE™: A multi-crystalline liquid admixture is designed to block the pores and the concrete matrix from the inside and improve long-term concrete durability and performance before the structure ever faces its first freeze-thaw cycle or deicing season. As a permeability-reducing admixture (PRA), it is ideal for sustainable infrastructure and pavement construction. MCE is simply dosed into the mixture as a concrete enhancer, similar to dosing other concrete liquid admixtures.
Both are based on the same principle: concrete admixtures for waterproofing should not merely be applied to the surface to prevent water from seeping through; they should change the internal pore structure of the concrete and stop water from seeping in in the first place.

Finding the Best Admixture for Concrete, for the Job

There's no single answer to what's the best admixture for concrete; it depends on what the structure needs to resist and when in the process you're able to intervene. If you're a contractor, engineer, or specifier looking to build resistance in at the batching stage rather than treat problems after the fact, MAG-SIL and MCE give you options that work with standard batching processes and familiar SCM handling, without complicating your mix design workflow. It's also worth noting that this category is not the place for an accelerator admixture in concrete or concrete admixtures for high early strength, where the goal is faster set times or early-age strength gain rather than long-term durability. Chem-Crete's enhancers are designed for the opposite end of the timeline: long-lasting performance, when the structure is dealing with real-world traffic, weather, and chemical exposure rather than a 28-day test cylinder.

Built for Structures That Can't Afford to Fail

Concrete is the material that's expected to last, which is why it's a choice specified by all kinds of entities, including highway departments, airport authorities, municipalities, and engineers. When the underlying mix is fighting permeability, ASR, and chloride intrusion from day one, that promise gets a lot easier to keep. That's the benefit a structural construction company reaps when it addresses these admixtures in its project mix design in the beginning. It leads to fewer surprises during the service life of the pavement, bridge, or structure, and less need for repair and retrofit down the line. Concrete Admixtures and Enhancers is a foundational category in the Chem-Crete lineup, and that's by design. Getting the internal chemistry right is often the single highest-leverage decision on a project, long before anyone talks about sealers, coatings, or repairs. FAQs Que : Can MAG-SIL and MCE be used together in the same mix? Ans : Each of MCE and MAG-Sil is a crystalline waterproofing admixture that also enhances concrete Compressive Strength. Each is designed to work as a standalone enhancer added at batching, and project-specific compatibility should be confirmed with our technical data sheets or our team, since mix designs vary by project and local materials. Que : Do these admixtures replace the need for surface sealers or waterproofing treatments? Ans : Not entirely. They reduce permeability and improve internal resistance to water and chlorides, but can still be used in conjunction with surface protection in many projects to provide maximum long-term protection, especially in high exposure environments. This depends on the project requirement. Que : How are these products added to a concrete mix? Ans : MAG-SIL is a powdered admixture added at the time of batching, similar to fly ash or silica fume, or incorporated into the cement at the point of manufacture. MCE is also introduced during batching to work throughout the concrete matrix; it can also be added to a concrete trans-mixer before placement.

Water Proofing & Moisture Blockers

Water is persistent. It doesn’t need to force its way through concrete; a tiny pore, hairline crack, or years of unchecked vapor pressure can be enough to create an entry point. And once it happens, the damage escalates rapidly: rusty rebar, spalling, scaling, mildew growth on concrete, mold growth in concrete, ruined flooring, failed roofs. A reliable concrete moisture blocker isn't a nice-to-have on a structure meant to last decades; it's foundational. International Chem-Crete built its Waterproofing & Moisture Blockers line around that reality, addressing everything from straightforward concrete waterproofing to subfloor vapor condensation and subfloor mold problems that surface long after a project is considered finished.

Why "Waterproof" Isn't One-Size-Fits-All

Ask ten contractors what concrete waterproofing means, and you'll get ten different answers, because the right approach depends entirely on where the water is coming from and what the structure needs to resist. A below-grade foundation dealing with hydrostatic pressure needs a different basement concrete sealer than a rooftop dealing with UV exposure and ponding water, and a subfloor dealing with vapor emission needs something different again. That's why this category isn't a single product, but a system of solutions:
  • CHEM-CRETE® SOFIX® CCC® 100 & CCC® 700: Hydrophilic and hygroscopic concrete vapor blockers, formulated for vapor transmission rates up to 12 and 18 lbs per 1,000 ft² every 24 hours. Where subfloor vapor condensation drives mildew growth on concrete and flooring failures, these products are designed to intercept moisture before it ever reaches the surface.
  • CHEM-CRETE® YUFIX® CCC® 1000: A water-based concrete and masonry water repellent and crystalline penetrating sealer, and a practical concrete sealer for surfaces that need long-term repellency and adhesion strength without changing their appearance.
  • CHEMCRETEX® CEM600: A crystalline cementitious coating that works its way into the concrete's own pore structure, forming genuine concrete moisture blockers from within rather than just setting on top of it.
  • CHEM-CRETE® CCC® 150: A cementitious coating built as a durable, code-friendly basement concrete waterproofing and general-purpose barrier waterproofing coating against water intrusion.
  • CHEM-CRETE® FLEX CCC900: A two-component, acrylic-modified, flexible cementitious coating designed to accommodate structural movement, giving it a natural concrete crack-healing ability in places where rigid coatings tend to fail and lose adhesion strength.
  • CHEM-ROOF 550: A one-component, water-based elastomeric coating built for concrete waterproofing on roof systems, standing up to weather, UV, and ponding without the seams and failure points of traditional membranes.
  • CHEM-SHIELD CCC800: An architectural textured structural coating that combines moisture protection with a finished, presentable surface that doesn't have to look purely industrial.

Choosing the Right Concrete Waterproofing & Moisture Blockers

The common denominator across all eight products is the same philosophy: a concrete moisture barrier should match the water problem it's solving, not just check a box on a spec specification sheet. Hydrostatic pressure from groundwater calls for a different chemistry than moisture vapor moving up through a subfloor, and a concrete sealer chosen for a basement wall will look nothing like the coating built for a roof deck. For departments of transportation, municipalities, airport authorities, engineers, and contractors specifying protection on real infrastructure, that distinction matters. Getting the waterproofing wrong doesn't just mean a repair bill; it means water finding its way back to the rebar, the finishes, or the structure underneath, often in places that are expensive and disruptive to access again.

Protection That Starts at the Source

Every product in this line shares Chem-Crete's core philosophy: understand exactly how and where water is entering a structure, then design a barrier that stops it at that specific point, whether it’s a capillary network, rooftop membrane, construction joint, or a recurring crack. That's what nearly five decades of research and field testing look like in practice, and it's why this category remains one of the most specified in the Chem-Crete lineup. FAQs Que : How do these products address subfloor mold problems and vapor issues under flooring? Ans : SOFIX CCC 700 and SOFIX CCC 100 are concrete vapor moisture blockers designed to control vapor emission and subfloor vapor condensation before it reaches flooring adhesives or finishes, addressing the root cause of subfloor mold problems and mildew growth on concrete rather than just masking the symptoms. Que : What's the difference between a basement concrete sealer and a cementitious coating? Ans : A basement concrete sealer like SOFIX CCC 700 and SOFIX CCC 700 are is typically a thinner moisture treatment for surfaces that need protection internally without a visible film. A cementitious coating like CCC 150 or CEM600 builds a thicker, more durable barrier, which is often the better choice for structures under active hydrostatic pressure. Que : Can FLEX CCC 900 actually heal cracks, or does it just cover them? Ans : FLEX CCC900 is a flexible cementitious coating engineered to accommodate structural movement, so it bridges and seals hairline cracks as they form rather than cracking alongside them. This helps maintain adhesion strength over time, compared with rigid coatings that lose contact once crack movement occurs.

Heritage

Protecting Historic Structures With Modern Waterproofing Technology

Historic buildings require specialized care to preserve their architectural character while protecting them from moisture, weather, and long-term deterioration. To protect historic structures, Chem-Crete provides advanced solutions, including CHEM-CRETE® HERITAGE CCC® 110, made to preserve the performance of older structures. Our approach combines proven waterproofing technology with practical construction expertise to protect masonry, exterior surfaces, foundations, and other vulnerable areas without compromising the character of heritage properties.

Exterior Services For Historic Structures for Long-Term Protection

Historic exteriors can experience deterioration from rain, humidity, freeze-thaw cycles, water intrusion, and aging construction materials. Our exterior services for historic structures address these challenges through targeted surface protection and waterproofing treatment of historic properties. Chem-Crete solutions reduce moisture penetration and protect concrete and masonry surfaces against conditions that contribute to cracking, staining, spalling, and structural deterioration. Getting the assessment and product selection right is essential when working with buildings that require careful preservation and heritage structure preservation.

Heritage Structure Waterproofing

Water intrusion is one of the most common threats to historic structures. Effective heritage structure waterproofing stops moisture before it penetrates vulnerable surfaces and contributes to long-term damage. Chem-Crete offers specialized waterproofing technologies designed for concrete, masonry, and other construction applications, including CHEM-CRETE® HERITAGE CCC® 110, a topical, dual-crystalline treatment that penetrates existing surfaces without leaving a visible residue. These treatments form a protective, colorless sealer while allowing project teams to address the specific characteristics and requirements of an existing historic structure.

Heritage Masonry Waterproofing Solutions

Historic masonry requires a thoughtful approach because traditional brick, stone, mortar, and concrete may react differently to modern construction treatments. Our heritage masonry waterproofing solutions protect exterior surfaces from moisture while supporting the preservation objectives of the project. HERITAGE CCC 110 works within the pores of the material rather than sealing the surface shut, so it reduces water absorption and permeability, improves surface durability, and limits the effects of repeated moisture exposure while supporting the structure's ability to breathe.

Waterproofing Historical Buildings

Waterproofing Historical Buildings requires more than simply applying a conventional coating. Historic properties may contain aging substrates, unique masonry assemblies, decorative elements, and construction methods that require specialized consideration for proper architectural conservation. Chem-Crete technologies, including HERITAGE CCC 110, give project professionals a way to address moisture-related concerns across concrete and masonry applications. By reducing water penetration and improving surface protection, the right waterproofing treatment preserves vulnerable areas and supports the long-term performance of the building.

Key Benefits of Heritage Waterproofing

A properly selected waterproofing treatment can help historic property owners, restoration professionals, architects, and contractors manage moisture-related deterioration while supporting long-term preservation objectives.
  • Moisture protection: Reduces water penetration through concrete and masonry surfaces
  • Surface durability: Improves resistance to weathering and environmental exposure
  • Historic preservation: Protects existing structures while maintaining their architectural character
  • Vapor permeability: HERITAGE CCC 110 reduces water permeability with little to no effect on vapor permeability, allowing existing structures to continue to breathe.
  • Long-term performance: Extends the service life of treated construction materials
  • Versatile applications: Solutions apply across a range of historic concrete, masonry, and exterior construction projects, applied using handheld sprayers, commercial sprayers, rollers, or paint brushes.

Protect Historic Structures for the Future

Preserving a historic building requires balancing its original character with the need for modern protection. Chem-Crete provides construction technologies that help restoration and construction professionals solve moisture penetration, surface deterioration, and durability problems. Whether the project involves exterior services for historic structures, heritage masonry waterproofing, or Waterproofing Historical Buildings, selecting the appropriate treatment is an important part of architectural conservation and protecting valuable structures for years to come. Frequently Asked Questions Que : What is heritage structure waterproofing? Ans : Heritage structure waterproofing is the application of specialized moisture-management and waterproofing treatments to historic or heritage buildings. The goal is to reduce water penetration and protect vulnerable construction materials from moisture-related deterioration while respecting the characteristics and preservation requirements of the existing structure. Que : Why is waterproofing important for historic buildings? Ans : Water can contribute to staining, cracking, freeze-thaw deterioration, corrosion, masonry damage, and other forms of deterioration. The right waterproofing limits moisture exposure and supports the long-term durability of historic concrete and masonry surfaces. Que : Can historic masonry be waterproofed? Ans : Yes. Heritage masonry waterproofing treatments, such as HERITAGE CCC 110, work on brick, stone, concrete, and masonry applications. However, the existing substrate, construction type, condition, exposure, and preservation requirements should be evaluated before selecting a treatment. Que : What should be considered when waterproofing a historical building? Ans : Important considerations include the condition and composition of the existing substrate, sources of water intrusion, climate, drainage, vapor movement, appearance requirements, and the preservation objectives of the project. Que : Who should handle historic exterior waterproofing? Ans : Historic exterior waterproofing should be planned with professionals experienced in restoration, construction materials, and moisture management. Architects, engineers, contractors, preservation specialists, and qualified product professionals can help determine the appropriate approach for a particular structure.

Under Water Applications

Advanced Solutions for Demanding Underwater Applications

Underwater applications demand materials engineered to perform where conventional products fail. As an experienced partner, Chem-Crete provides construction chemical solutions built for water exposure, pressure, difficult access, and challenging substrate conditions. Our technologies support contractors, engineers, municipalities, and infrastructure professionals working on concrete and steel structures that require repair, sealing, grouting, or protection below the waterline.

Crack Sealing in Swimming Pools

Cracks in swimming pool structures rarely stay dry long enough for conventional repair materials to bond properly. CHEM-UNDERWATER INJECT and CHEM-GUARD UNDERWATER solve that problem directly. It's a two-component epoxy injection resin engineered to repair wet structural cracks above the waterline or fully submerged, with a low viscosity and long pot life that lets it flow into and seal the full length of a crack before it begins to cure. For pool decks, shells, and surrounding structural concrete, that means crack sealing in swimming pools can happen without draining the pool or waiting for the surface to dry out first.

Stopping Water Leaks in Hydraulic Structures

Dams, tunnels, retaining walls, and other hydraulic structures put constant pressure on every joint and crack in the concrete, and a leak that starts small rarely stays that way. CHEM-UNDERWATER INJECT and CHEM-GUARD UNDERWATER are formulated to fill and seal voids and subsiding cracks under real injection pressure, stopping water leaks in hydraulic structures at the source rather than masking them on the surface. They meet ASTM C881 Type II, Class B & C, giving engineers a product they can specify with confidence on critical infrastructure.

Sealing Precast Cofferdam

Cofferdams place enormous demands on sealing systems, since the joints between precast sections have to hold back water under constant hydrostatic pressure from day one. CHEM-GUARD UNDERWATER is built for exactly this kind of application. It's a two-component, 100% solids hydrophilic epoxy gel adhesive that cures and hardens fully submerged, forming a heavy-bodied, non-sagging seal at the joints. Sealing precast cofferdam sections with a product designed to cure underwater removes the guesswork that comes with trying to seal joints in dry conditions that won't stay dry for long.

Sealing Concrete Pile

Pilings are submerged or intermittently exposed for the life of the structure, which means the seal protecting them has to perform in the same conditions indefinitely. CHEM-GUARD UNDERWATER is purpose-built for pilings, drainage canals, abutments, structural supports, and other steel or concrete elements sitting in fresh or salt water or in splash zone exposure. Sealing concrete pile surfaces with a hydrophilic epoxy gel that hardens underwater protects the structure exactly where conventional coatings struggle most.

Underwater Cementitious Grouting

Grouting work below the waterline calls for a material that flows into place and holds under pressure without washing out. CEM9000 is built for exactly that. It's a ready-to-use, one-component, non-shrink cementitious grout made from Portland cement, graded silica sand, and flow-improvement compounds, mixed on site with water alone. Its low washability keeps the mix intact as it's placed underwater, while the non-shrink formulation and early high strength make it suited to underwater cementitious grouting projects like setting bolts and anchor bars, filling cavities, and repairing structural voids.

Key Benefits of Underwater Construction Solutions

Specialized construction materials give professionals a direct way to address the unique challenges of submerged concrete and steel infrastructure.
  • Underwater cure performance: CHEM-UNDERWATER INJECT and CHEM-GUARD UNDERWATER are engineered to cure fully submerged, not just tolerate moisture.
  • Crack and leak control: CHEM-UNDERWATER INJECT fills and seals cracks and voids under injection pressure, stopping leaks at the source.
  • Joint and pile protection: CHEM-GUARD UNDERWATER forms a non-sagging seal on cofferdam joints, pilings, and other submerged steel and concrete elements.
  • Grouting flexibility: CHEM-UNDERWATER INJECT doubles as a grouting material for bolts and anchor bars in underwater applications.
  • Specification-ready performance: Both products meet ASTM C881 requirements for structural epoxy systems.

Reliable Solutions for Water-Exposed Infrastructure

Underwater construction rewards planning and the right material for the job, not a one-size-fits-all coating. From crack sealing in swimming pools and stopping water leaks in hydraulic structures to sealing precast cofferdam joints, sealing concrete pile surfaces, and underwater cementitious grouting, International Chem-Crete provides technologies engineered specifically for submerged and water-exposed conditions. With the right product matched to the right application, professionals can stop deterioration at the source and protect critical infrastructure for the long term. Frequently Asked Questions Que : Can concrete cracks really be sealed while still underwater? Ans : Yes. CHEM-UNDERWATER INJECT is formulated to cure fully submerged, so cracks in pool structures, tunnels, and hydraulic infrastructure can be injected and sealed without draining or drying the surrounding area first. Que : How does CHEM-UNDERWATER INJECT stop leaks in hydraulic structures? Ans : It's a low-viscosity epoxy resin injected under pressure, where it flows into and fills existing cracks and voids before curing, sealing the leak path at the source rather than covering it on the surface. Que : How is a precast cofferdam joint sealed underwater? Ans : CHEM-GUARD UNDERWATER, a hydrophilic epoxy gel adhesive that cures underwater, is applied to the joint and left to harden in place, forming a non-sagging seal even under constant water exposure. Que : What makes a product suitable for sealing concrete piles? Ans : A piling sealant needs to cure and perform indefinitely in submerged or splash zone conditions. CHEM-GUARD UNDERWATER is formulated specifically for steel and concrete pilings exposed to fresh or salt water on a constant or intermittent basis. Que : What makes CEM9000 suitable for underwater cementitious grouting? Ans : CEM9000 is a one-component cementitious grout formulated with low washability, so it resists dispersing into the surrounding water as it's placed. Combined with its non-shrink formulation and pumpable consistency, it's suited to filling cavities, setting anchor bars, and repairing structural voids underwater.

Freezers & Cold Storages

Cold storage environments push flooring to its limits. Sub-zero temperatures, constant condensation, heavy pallet traffic, and aggressive cleaning cycles all work against a standard concrete floor, and most coating systems simply aren't formulated to cure in the cold in the first place. That's the gap CHEM-FREEZER is made to close. As a freezer coating and refrigerator coating engineered specifically for sub-zero application, it gives facility owners and contractors a way to protect concrete floors in conditions where ordinary epoxy systems fail before they ever set.

Freezer Coating and Refrigerator Coating for Sub-Zero Environments

Most epoxy coatings need warmth to cure properly, which makes them a poor fit for commercial freezers, cold stores, and refrigerated facilities that never warm up without shutting down. CHEM-FREEZER is a two-component, solvent-free, 100% solids liquid epoxy binder system formulated to cure at temperatures below 0°F (-18°C). That single distinction is what separates a genuine freezer coating from a refrigerator coating adapted from a standard product line, and it's why CHEM-FREEZER is used across dairies, milk processing centers, fisheries, meat processing facilities, and cold stores operating at extremely low temperatures year-round.

Freezer Epoxy Coating Built to Cure Below Zero

A freezer epoxy coating has to do more than resist moisture and traffic. It has to actually cure in an environment most epoxy chemistry can't tolerate. CHEM-FREEZER is a sub-temperature epoxy purpose-built for that challenge, combining epoxy resin and hardener into a clear liquid binder formulated for temperatures below -18°C. Mixed with dry silica sand, it becomes a custom-designed epoxy repair mortar suited to deep-section concrete floor repairs, giving facility teams a single system that handles both coating and structural repair in the same sub-zero environment.

Cold Storage Floor Coating and Freezer Floor Coating

A cold storage floor coating and a freezer floor coating face the same core problem from different angles: constant temperature extremes wear down concrete faster than almost any other operating environment. CHEM-FREEZER addresses both by curing reliably in the cold rather than requiring facilities to warm the space before installation, a requirement that's rarely practical in an active cold storage or freezer operation.

Freezer Floor Repair and Walk-in Cooler Repair

Freezer floor repair and walk-in cooler floor repair both have the same limitation: the space can't always be taken out of sub-zero operation long enough for a standard repair mortar to cure. CHEM-FREEZER solves that directly. Because it's formulated to set at temperatures below -18°C, it can be used to repair deep sections of concrete floor without shutting down refrigeration or waiting for conditions to warm. For a walk-in cooler floor repair where downtime is expensive, that's the difference between a quick, in-place fix and pulling a facility out of service.

Key Benefits of Cold Storage Flooring Solutions

Specialized flooring and surface protection can help facilities manage the demanding conditions associated with refrigerated environments.
  • Moisture protection: Reduces water penetration and moisture-related deterioration in concrete surfaces.
  • Durable surfaces: Resists everyday traffic, abrasion, and operational wear.
  • Temperature considerations: CHEM-FREEZER is engineered specifically for environments where floors experience sub-zero operating temperatures.
  • Easy maintenance: A properly selected surface supports routine cleaning and maintenance requirements.
  • Long-term concrete protection: Protects existing concrete and extends its service life.

Protect Your Cold Storage Flooring

Cold storage and freezer facilities need a flooring system built for actual operating conditions, not ideal ones. From freezer coating and refrigerator coating applications to freezer epoxy coating, cold storage floor coating, and freezer floor coating projects, CHEM-FREEZER gives contractors and facility owners a sub-temperature epoxy that actually cures where it's applied. Whether the need is a full floor coating or a freezer floor repair on a section that's already failing, having a system built for sub-zero conditions means the work gets done without shutting the facility down. Frequently Asked Questions Que : Why aren't standard epoxy coatings suitable for freezers? Ans : Most epoxy systems require warmth to cure and simply fail to set at freezer or refrigerator temperatures. CHEM-FREEZER is formulated specifically to cure at temperatures below 0°F (-18°C), which is why it works as a freezer coating and refrigerator coating where conventional products fail. Que : What temperatures can CHEM-FREEZER be applied in? Ans : CHEM-FREEZER is designed to cure at temperatures below -18°C (0°F), making it suitable for commercial freezers, cold stores, and refrigerated facilities that operate at sustained sub-zero temperatures. Que : Can CHEM-FREEZER be used for floor repairs as well as coating? Ans : Yes. Mixed with dry silica sand, CHEM-FREEZER becomes a custom-designed epoxy repair mortar for deep-section concrete floor repairs, making it suitable for both freezer floor repair and walk-in cooler floor repair projects. Que : Does the facility need to be warmed up before applying CHEM-FREEZER? Ans : No. CHEM-FREEZER is engineered to cure in sub-zero conditions, so it can be applied and cured without shutting down refrigeration or waiting for the space to warm. Que : What industries typically use this kind of freezer flooring solution? Ans : CHEM-FREEZER is commonly used in dairies and milk processing centers, fisheries and meat processing facilities, and any cold storage operation that needs reliable flooring and repair performance at temperatures below -18°C.
