CEM290-H

Hot Set Hydraulic Cement (45 seconds)

CEM290-H is a quick setting, one component hydraulic cement compound, used to instantly stop running water or seepage leaks in masonry or concrete. CEM290-H is non-shrinking, non-metallic and non-corrosive which requires only potable water for mixing and achieves initial set in 45 seconds, even when applied under water.

Technical Data Sheet

USES

CEM290-H is used above or below grade, interior or exterior, to stop seepage and flowing water leaks in most concrete and masonry walls and floors. The initial fast set, high strength and controlled expansion make CEM290-H the ideal packing material for use in:

 

  • Dams and Reservoirs
  • Tunnels and Sewers
  • Bridges and Cisterns
  • Swimming Pools, Elevator Shafts and Fountains

Foundations etc.

ADVANTAGES

  • Rapid initial setting in 45 seconds
  • Non-shrinking
  • Non-corrosive
  • Suitable for use in potable water tanks
  • Non-metallic
  • High strength with controlled expansion

Set Time: 45 seconds

Mixed Density: 17.4 Lb/Gal (2.09 Kg/L)

Mixing Ratio:  1 Potable Water to 3.5 CEM290-H by volume

APPLICATION

Surface Preparation: Cut or chisel out the concrete or masonry surrounding the hole or crack, to a minimum depth and width of 5/8 to 6/8 inches (18-20 mm).  Under cut the crack or hole into a ‘V’ shaped cut to provide mechanical bond during initial set and final cure.  Flush, blow or vacuum loose particles, dust or other foreign materials from the prepared areas.  When the relief point for water leak is ready, treat the surround by simply rubbing the dry powder of CEM290-H into the wet surface.

 

Mixing: Pour potable water into a clean mixing container and add CEM290-H. Use approximately 1 part water to      3.5 parts CEM290-H by volume. Mix rapidly with a trowel to the consistency of stiff putty with no slump.  Mix no more than 30 seconds. CEM290-H will flash set in 45 seconds. Properly mixed CEM290-H can be hand-formed into a ball.

 

Mixing should always be done carefully using Rubber Gloves.

 

Application:

General Patching:  Force CEM290-H into the crack or hole even with surface.

 

Patching Active Leaks: Hold mixed CEM290-H in hand until warm. Start at top opening, firmly forcing CEM290-H into small section of the crack. Hold until set. Continue working down until crack is completely filled and water stops running.

 

Floor-wall Patching: Follow the above method for similar conditions.

 

Expansion/Contraction Cracks: Use CEM290-H to stop running water leaks.  Do not fill crack completely to surface. Allow approximately ½ inch (13 mm) depth and fill with a flexible joint sealer.

 

Note: In all above methods, use safety rubber gloves for hand protection.

 

Curing: Standard concrete curing procedures should be followed to prevent rapid water loss and consequent loss of strength.

 

Coverage:

2.2 Lb (1 Kg) 0.6 Liters
20 Lb (9.07 kg) 0.19 ft3 (5.44 Liters)
50 Lb (22.68 kg) 0.48 ft3 (13.61 Liters)

 

2.2 Lbs (1 kg) of CEM290-H will repair approximately a 26 inches (65 cm) long crack/cut of 20 x 20 cm.

 

Cautions:

  • Do not re-temper CEM290-H.
  • Do not apply CEM290-H to frozen surfaces.
  • In hotter climates, mix CEM290-H with cold water.
  • In cold weather, mix CEM290-H with warm water.
  • Use CEM230 for large patches and for under water patching.

Cleaning: clean tools and mixing equipment with water immediately after use.

STORAGE

Indefinite shelf life when stored in cool, dry place in unopened drums.

SAFETY

CEM290-H is a non-flammable and non-toxic in nature. Avoid contact with eyes and skin as it may cause irritation due to its alkaline nature. Splashes of CEM290-H should be washed off immediately with clean water. Wear necessary gloves and dust mask.
