PAVIX QUESTIONS

001. What tests have been preformed to verify how well PaviX works on concrete?
PaviX has undergone a battery of ASTM specified tests by an independent testing laboratory familiar
with concrete testing. The current ASTM tests PaviX has been analyzed for are the following: Freeze-
Thaw test C-666, Scaling test C-672, Product Penetration C-856, Abrasion Resistance C-944, Water
Soluble Chloride C-1218, Pull-Off Strength test D-4541 and Water Vapor Transmission E-96.

002. How deep does the PaviX crystalline formation penetrate the concrete?
The reactions that initially take place at the concrete surface is a liquid application that immediately
penetrates into the capillary pores of the concrete surface. Over a short period of time depending on
humidity levels the liquid PaviX turns into a gel which in –turn forms hygroscopic and hydrophilic
crystals. PaviX will search out moisture to the bottom of the capillary tube regardless how long it is in
length.

003. How long does PaviX last?
PaviX product application is permanent. Once placed, the crystals remain active indefinitely. Its
unique crystalline growth structure will not deteriorate.

004. How resistant is PaviX to chemicals?
Based on independent testing PaviX is not affected by a wide range of chemicals including mild acids, solvents, chlorides and caustic materials. It is resistant to oils, fuels and prevents dusting.

005. Is PaviX affected by temperature, humidity, ultraviolet and oxygen levels?
Humidity, ultraviolet and the oxygen level (oxidation) have no effect on a PaviX. As humidity
increases, the crystals actually swell in the capillaries to block moisture from entering the capillary.

006. Does PaviX protect reinforcing steel?
Yes. By preventing the intrusion of chemicals, salt water, sewage and other harmful materials, PaviX
protects concrete and reinforcing steel from deterioration and oxidation. If corrosion has already
present, it will slow the process by not allowing moisture to enter the capillary tube.

007. Does PaviX protect concrete against freeze/thaw damage?
Yes. By blocking the intrusion of water into concrete, PaviX protects the concrete from the damaging
effect of repeated freeze/thaw cycles.

008. Is PaviX toxic?
No. PaviX contains no volatile organic carriers (VOC) is completely safe to the environment.

009. Can PaviX be applied against hydrostatic pressure?
Yes. Because PaviX is not dependent upon adhesion to the concrete surface and instead becomes an integral part of the concrete mass through crystallization, it is capable of resisting hydrostatic pressure from either side (positive or negative) of the concrete.

010. Can PaviX be applied while the concrete is wet?
Yes and No. Best results are obtained when the concrete is dry or slightly moist but not wet. PaviX
being water based carries the crystalline growth deep into the concrete. PaviX, once applied will not be affected if rain were to fall shortly after application. PaviX starts working immediately after application.

011. Is PaviX used to waterproof cracks, joints and other defects in concrete?
Yes. PaviX has a specific repair system that utilizes its unique crystalline waterproofing technology to
stop water flow through up to 1/16 cracks. In the case of expansion joints or chronic moving cracks, a
flexible sealant is recommended.

012. Is PaviX suitable for use on surfaces other than concrete?
PaviX is totally compatible with the chemistry of concrete, whether poured-in-place, pre-cast or
concrete block. PaviX may also be used on mortar, plaster, stucco, terrazzo, exposed aggregate and any sand aggregate cement combination.

013. What is the appearance of a PaviX coating?
PaviX is a colorless, transparent liquid; initially the concrete will appear darker for several days until the material has dried the concrete. When moisture is present, PaviX treated surfaces will not change in color because no moisture can penetrate into the concrete.

014. Can paint and other finishing materials be applied over a PaviX coating?
Yes. Paint, cement purge coats, plaster and stucco can be applied or installed over concrete protected with PaviX. For detailed instructions, refer to PaviX "Specification and Application Information".

015. What are some typical PaviX applications?
PaviX can be applied to any concrete surface. Applications include Bridge decks, Airport Runways,
Reservoirs, Tunnels, Parking Structures, Sidewalks, Sewage and Water Treatment Tanks, Secondary
Containment Structures, Underground Vaults, Foundations, Roof Decks, and Below Grade
Construction.

016. How is PaviX different from other products?
The dual PaviX crystalline formation (hygroscopic & hydrophilic) for concrete waterproofing is
substantially different from traditional barrier products (membranes, cementitious coatings):
1. PaviX creates a crystalline structure deep within the pores and capillary tracts of the concrete mass to prevent the penetration of water and aggressive chemicals and also form a barrier at the surface of the concrete.
2. PaviX it is resistant to hydrostatic pressure.
3. PaviX will seal hairline cracks up to 1/16 inch.
4. PaviX will not deteriorate after years of intense service.
5. PaviX is permanent and crystals activates whenever moisture is present.

017. What are the application advantages of using PaviX?
The crystalline nature of the PaviX waterproofing system provides many application advantages:
1. PaviX is a single component dual crystalline hygroscopic & hydrophilic product.
2. PaviX is fluid applied water based material.
3. Application equipment from brooms, squeegee, hudson hand sprayers or 250-2500 gallon sprayer
units are readily available.
4. PaviX requires no special protection during backfilling or during placement of steel, wire mesh or
other materials.
5. PaviX can be applied on either side of a concrete surface – the negative or the positive (water
pressure) side.
6. PaviX forms a monolithic coverage that can be added to at any time.
7. PaviX is less costly to apply than most other methods.

018. What is the recommended application rate for PaviX?
Typically a coverage rate of between 150 – 250 square feet per gallon will provide ample coverage.
Consultation with the manufacturer’s technical department or your local PaviX representative for assistance in determining the appropriate dosage rate based on specific requirements and conditions of your project.

 

SILANE QUESTIONS

001. What is the composition of the crystalline material?
The base or foundation of the PaviX CCC100 crystal is Sodium Tartrate case # 868-18-8. There are other ingredients which give the PaviX CCC100 its special properties that increase the chemical resistance of the crystal structure and added properties that enhance and to add water repellency. These ingredients are proprietary and company secrets but none of the ingredients are toxic.

002. What are the by-products of its reaction within concrete?
The PaviX CCC100 does not react with any ingredients contained within the   concrete substrate. The only by-product that remains within the concrete substrate is the crystal structures which are designed for the protection of the concrete substrate as well as the reinforcing steel contained in the concrete substrate.

003. How do you know when you have applied enough of the system? Is it because you have used the recommended dosage?
International Chem-Crete’s research was very extensive in determining what amount of PaviX CCC100 was the optimum dosage for the protection of a high-way concrete substrate. Economics were not a determining factor in the recommended dosage. Performance of the product to concerning the protection of the concrete substrate was the only consideration. Appling more PaviX CCC100 product than the recommended dosage for a high-way concrete substrate will only waste product, but will not have an adverse effect on the substrate.

004. In your frequently asked questions brochure you claim that PaviX is resistant to hydrostatic pressure. What evidence have you got to support this?
The PaviX CCC100 technology is derived from the proven moisture blocker product lines International Chem-Crete has developed for concrete substrates over the past thirty-five years. Based on this successful technology, International Chem-Crete naturally employed this historically proven technology for the protection of high-way concrete substrates to elimination the moisture related problems well documented within this industry.

005. Question and Statement. Silane, for example, does not claim to be efficient when subjected to a hydrostatic head, i.e. where areas of ponding may exist?
Silane will not and can not make a claim that it can resist a hydrostatic head. The product is a surface treatment that is designed to only repel water intrusion for a limited time. It is not designed as a moisture blocker. Ponding water will have no effect on the PaviX CCC100 product, since it has been designed to block the intrusion of water, vapor or moisture into (from above or below) the concrete substrate.

005B. How does the actions of PaviX differ from those actions of Silane?
Silane degrades in the presents of ultra-violet light. PaviX CCC100 does not! Silanes, whether water based or solvent based are toxic. PaviX CCC100 is not! Silanes contain VOCs. PaviX does not! Silanes are toxic to the environment. PaviX CCC100 is not! Silanes can and are flammable and explosive. PaviX CCC100 is not! Silanes are not a permanent treatment. PaviX CCC100 is! Silanes increase the likelihood of carbonation of the concrete substrate. PaviX CCC100 does not! Silane is based on solvent technology. PaviX CCC100 is not!

006. Do the crystals bond themselves into the concrete matrix?
No the crystals do not bond themselves to the concrete substrate. The term that should be employed other than bonding is the PaviX CCC100 crystals occupy the voids and capillaries of the concrete substrate. Please keep in mind the PaviX CCC100 crystals are activated by the presents of moisture which can increase their size up to sixteen times when compared to their dry or dehydrated state. The crystals will last for the life of the concrete substrate, they are intertwined within the matrix, and they will not degrade.

006B. If, so does the concrete remain permeable to vapor, etc?
The PaviX CCC100 is not permeable in the present of vapor, moisture or water.

007. Has the effect of the system been considered in terms of the rate of carbonation of the concrete surfaces treated with PaviX, in comparison to those that remain untreated?
The unique property of the PaviX CCC100 water repellency helps eliminates the possibility of carbonation from reducing the higher PH levels of the concrete substrate because of its ability to keep the concrete substrate dry and the sealing of the voids and capillaries, further assuring the reinforcing steel an inert environment preventing corrosion of the steel reinforcement. Silanes require the alkali of the concrete substrate to create a reaction, which in turn reduces the PH levels within the concrete substrate. This elimination of the higher PH levels within the concrete substrate accelerates the possibility of carbonation leading to the deterioration of the concrete substrate and increasing the possibility of corroding the steel reinforcing structure.

008. What is the sodium and alkali content of PaviX? Would the application of PaviX lead to an enhanced risk of deterioration due to alkali aggregate reaction in structures?
PaviX CCC100 contains no free sodium (Sodium Tartrate is a dehydrate and the base of the catalyzed structure) and contains no alkali! A concrete structure treated with PaviX CCC100 is better protected from alkali aggregate reaction due to the fact that this reaction requires moisture to develop within the concrete substrate.
