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.
OEM High Quality Water-Swelling Rubber Water Stop

Products introduction:
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.

Performance advantages swellable waterstops:
Check water expansion under the influence of water to water. Used in buildings can be permanently being will swell. Shrinkage, water loss, durable and reliable, and is non-toxic harmless, no corrosion, no pollution, construction is convenient, quick, reliable quality, save work, time saving, low cost, etc.
Method of use Swelling Rubber swellable waterstops:
For a period of concrete pouring, construction joint interface after hardening and table dry, clear interface scum, extended along the construction joint of water stop stick in the construction joint interface, the direction of the vertical steel nail fixed so as to avoid displacement construction joint available. When joint lateral water stop can be put together with the lead wire bundle it tightly, and then on to the next period of construction.
Advantage Rubber  swellable waterstops:
1.High tensile strength, high tear resistance.
2.High break elongation rate, Less compression set.
3.Low fragility Temp, anti-aging ,anti-corrosion.
4.Easy installation, supply with vinous joint type .
5.Customized to design and construction.
