Bentonite Waterstops / Expansion Waterstop Strip
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 PN Type.
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.
Physical Parameter:
PN(BW) type
Item | Index | ||
BW-150 | BW-220 | BW-300 | |
Expansion Rate % | 150 | 220 | 300 |
Flow at high temperature(80ºC×5h) | No flow | ||
Low temperature test(-20ºC×2h) | No embrittlement |
Application:
PN bentonite rubber waterstop, is widely used in swimming pools, waste water / sewer solution projects, underground railway, tunnels, culverts, buildings etc, in the construction joints, expansion joints and cracks of concrete constructions. It is designed for water stop / waterproof of concrete joints.
