It does not depend on moisture activation to work as its mechanical properties depend on the bond to each side of the joint, and not the expansion of the product itself. Conseal CS231 is compressible within the joint and will provide an immediate and effective seal. Its follow on controlled expansion increases the seal and will accommodate small joint movements. Conseal CS231 is ideal as sealing strips for manholes, pipe penetrations and box culverts. It is a highly elastic gasket with substantial elongation capabilities. The heat of hydration assists with chemical bond to green concrete. Advantages „ No site welding - just butt and mould together „ Easy to handle - just prime the face of the concrete „ A moderate amount of surface irregularity can be accommodated Description Conseal CS231 is a low expansion butyl based hydrophilic sealing gasket. It is manufactured utilising a special mixing process which encapsulates the hydrophilic materials into a butyl rubber base thus creating a controlled moisture activated seal. Controlled expansion in the presence of water means that the Conseal CS231 will not soften to the point where it will extrude out of the joint compared to bentonite based highly expansive hydrophilic waterstops which must be fully contained within non-movement construction joints to be effective. Properties Form: Pliable Mastic Strip Colour: Black Expansion: Maximum 10% with 28 Days exposure to water (No Material Disintegration) Hydrostatic pressure: Up to maximum 207Kpa or a 21M head (depending on configuration) Specific gravity: 1.35 Penetration cone test: 40 ± 5 Service temperature: Minus 34°C to 82°C Installation Instructions Carefully brush off all loose dust and dirt. Apply Emer-Proof Self Adhesive Primer to the area to which the Conseal CS231 is to be fixed. Allow the primer to become tacky (approx. 15 mins) then firmly press the Conseal CS231 onto it ensuring that the alignment is to the Engineers’ specification. Apply moderate hand pressure using the heel of the hand and check that the Conseal CS231 is bonded to the primed strip. Remove the protective backing from the Conseal CS231 and knead together the overlapped ends at joins to form a continuous strip. Prime the other matching surface, allow the primer to become tacky (approx. 15 mins), then bring the pre-cast sections firmly together into the correct position.
