PRODUCT DOCUMENTS

Technical Data Sheet

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 full immersion in water followed by five days air-drying.
ConSeal CS 231 showed no visible signs of deterioration at the conclusion of 10 cycles of exposure.
