The Ultraband range covers internal and external waterstops made of plasticised PVC: types DV and DO for expansion joints, KhV, KhVS, KhO and KhOM for construction joints, and protective U-shaped DZ. The size is selected according to DIN V 18541 taking into account water pressure and total deformation; joints are welded with a jig or a thermal knife. The material has an elongation at break of at least 300% and works from −25 to +80 °C, and profiles KhV-320 and DV-320/20 are designed for a water pressure of 0.8 MPa.
