AKVASTOP SVG waterstop — joint seal for diaphragm walls

Waterstops and swelling profiles

Construction joints in diaphragm wall structures are sealed with the SVG profile, which is mounted in the stop-end formwork panels. The rubber version SVG-120 is rated for movements of 10/15/10/5 mm at water pressure of 0.30 MPa, the PVC-P version SVG-150 for 20/60/60/40 mm at 0.33 MPa. The field of application is hydraulic, buried and underground structures, including tunnels and metro.
