AKVASTOP PNB swelling bentonite profile — strip for construction joints
Bentonite strip on butyl rubber for construction joints, junctions and utility penetrations; resists water pressure up to 18 atm.
The KhOM model is intended for construction joints where the main waterproofing is a PVC membrane: the waterstop becomes part of the leak protection system together with the membrane. The profile is a formwork type made of PVC-P and comes in sizes KhOM-200-3/20, KhOM-240-4/20, KhOM-320-4/20 and KhOM-320-4/30. The permissible water pressure is from 0.15 to 0.33 MPa depending on the size; it is supplied in coils of 30 or 50 m.
