AKVASTOP DR waterstop — repair waterstop for expansion joints

Waterstops and swelling profiles

The DR repair waterstop is needed when the expansion joint of an already built buried or underground structure leaks and its sealing has to be restored. The rubber profile DR-250/50 works at water pressure of 0.29 MPa, the PVC-P profiles DR-210/30 and DR-230/50 at 0.33 MPa. DR-230/50 accommodates the largest movements: joint tension and transverse shear of up to 120 mm.
