NSF Standard 61 Certified, Safe for Drinking Water Applications

ADHESIVE SEALING GASKET

ConSeal CS-231 Waterstop is a rubber-based product that has been formulated with hydrophilic compounds that allow it to expand in a controlled fashion when exposed to moisture, thereby sealing off leaks and restoring long-term, watertight joint integrity. Traditional, clay-based waterstop products, on the other hand, expand uncontrollably and eventually deteriorate, causing a complete loss of joint integrity.

HYDRATION-DEHYDRATION CYCLE TESTING

The test evaluates the integrity of CS-231 Waterstop when exposed to cycles of hydration and dehydration. A cycle consists of nine days of full immersion in water followed by five days air-drying. ConSeal CS-231 showed no visible signs of deterioration after completion of 10 cycles of exposure.
