AKVASTOP DZ waterstop — U-shaped waterstop for expansion joints

Waterstops and swelling profiles

The universal U-shaped DZ waterstop is suitable both for new construction and for restoring the tightness of expansion joints in underground structures already in service. Rubber profiles are made in sizes DZ-100/25-4/25 and DZ-130/25-6/25, PVC-P profiles — from DZ-140/20 to DZ-140/100. The widest version accommodates joint compression of 90 mm and tension of 250 mm, and the permissible water pressure across the range is 0.28–0.43 MPa.
