HydroBloc Rapid has been unrivalled for over 25 years! Rubber-elastic, swellable with perfect flank adhesion. The solution for repairing expansion joints and sealing water ingress. System 3-S stands for simple and efficient work. The single shot system means sealing and stopping water ingress with just one product.
No change of material, no re-injection, no foam.
Controlled filling with highly elastic rubber that swells on contact with water after curing and thus actively closes changes in the joint cross-section.
