CONQOR 87B WATERSTOP is a delayed-swell waterstop gasket.

CONQOR 47B and 87B waterstops are butyl hydrophilic polymer based gasket, which has a built-in delay system that activates after approximately 8-24 hours of constant exposure to water.

CONQOR waterstops are manufactured utilizing a specialized mixing process which encapsulates hydrophilic materials into a rubber base creating a controlled, moisture-activated gasket. This gasket has the structural integrity of a rubber-based sealant; the features of a butyl sealant; as well as the ability to expand to create a SELF-HEALING JOINT MATERIAL.
