AKVASTOP KhVN waterstop — internal waterstop with a swelling cord

Waterstops and swelling profiles

The KhVN design combines an internal PVC-P waterstop with a swelling rubber cord, so the profile needs a smaller embedment depth in the concrete. It is used in construction joints and in floor-to-wall and wall-to-roof-slab junctions. Sizes KhVN-80, KhVN-120 and KhVN-150 come with a Ø4 or Ø6 cord, and the permissible water pressure is from 0.57 to 0.97 MPa. It is supplied as a kit: a 50 or 30 m coil with 150 or 90 fixing elements.
