Allows concrete to gain full strength before expansion, and then the butyl hydrophilic polymer based gasket activates after approximately 5-10 days of constant exposure to water.
Unaffected by repeated wet and dry cycles. 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.
Very easy to handle and install.. No on-site welding required as with PVC waterstops. Excellent adhesion, can be bedded into wet concrete and is suitable for use in horizontal and vertical joints.
