Hydrophilic bar/Bentonite Waterstops/swellable waterbar for concrete joint
Water stop strip is a swelling rubber water line on the basis of the ordinary rubber water-stop and we have two types of water stop trip, they are PZ Type and BW Type.
Swellable waterstops  for Expension Joints bar under the influence of water.

Bentonite Waterstop Bar for Concrete Project

PN (BW) consists of polymer, inorganic absorbent of water stop expansion and the synthesis of auxiliary materials and rubber with self-adhesive can be a new type of building waterproof material. Encounter water suction volume expansion, the gaps between the new and old concrete compaction, form a waterproof plastic colloid. The product to solve the problem of leakage problems of concrete construction crack pioneered the new path.

It can be divided into BW type and PZ Type. Any client can select it according to different demand of water-proof construction.
