Featured Products:
Hydrophilic rubber string. Used to waterproof sheet pile, cracks, and CIPP pipe. Capable of stopping active leaks. String size should be 1.2 times the joint width. When stretched the string diameter can be reduced by about 40%. This enables it to get instant compression when inserted and release in the joint.

Product Description
ADEKA ULTRASEAL® KM-STRING is a chemically modi-fied natural rubber (vulcanized) product. The manufacturing process chemically bonds a hydrophilic agent to the rubber. This permits the seal to undergo controlled expansion when exposed to moisture. This expansion capability provides a “double locking” waterstop i.e. one from rubber’s natural resilience and one from expansion pressure generated when it is exposed to water. It will expand approximately 3 times by volume. Any void, within the limits of the product’s volume expansion coefficient, will be filled by the expansion of the KM when it is hydrated.
Size
4mm approximately 3/16″ and 6mm approximately 1/4″
packaged 165 feet per box
