CORKJOINT SUPERWELL 47B HYDROPHILIC BUTYL WATERSTOP SEAL 25mm x 19mm

Specification 1) Product Size :  5meter(L) x 19mm(thk) x 25mm(W) per roll. 2) Product Form :  Hydrophilic Polymer based. 3) Application Temp. Range :  -22°C to 52°C. 4) Hydrostatic Pressure Resistance :  60 metres. 5) Unlike many of the traditional clay-based products, Superswell® 47B being hydrophilic polymer based, will not expand to a point that the hydration process itself leads to the possible “disintegration” of the waterstop due to its expansion control system. This is an important issue when the engineers are looking for a seal in vertical construction joints where the joint can open due to excessive shrinkage in the concrete. In-field experience has proven that products which continually expand, may lose their structural integrity and begin to wash away from the joint when subject to a constant flow of water or from high water pressure.
