Hydrophilic and Chloroprene Rubber
Hyperseal DP-0725H is a high performance, expanding hydrophilic rubber waterstop, with internal non-expanding chloroprene rubber layer, which swells to form a long-lasting water-tight compression seal.
The double-layer design ensures that expansion is spread across the joint to achieve highly effective sealing. The swelling action is the result between water and hydrophilic groups which are part of the Hyperseal DP molecular structure. This waterstop comes with a self-adhesive backing making installation easy.
