AKVASTOP DO waterstop — external formwork waterstop for expansion joints

Waterstops and swelling profiles

Type DO belongs to the formwork, that is external, waterstops: the profile covers the expansion joint from the outer side of a foundation, underground structure or tunnel. The range includes rubber profiles DO-220/25-4/25 and DO-270/25-6/25 and seven PVC-P sizes — from DO-240/20-4/25 to DO-500/50-6/30. The permissible water pressure is 0.28–0.47 MPa; for the wide profiles DO-320/50, DO-400/50 and DO-500/50 joint tension can reach 120 mm, and the last two are made to advance order.
