PN (BW) waterstop strip is a new type of waterproof building material with self-adhesive property synthesized by polymer, inorganic water-swelling material, rubber and additives. It could absorb water and expand volume, compact the gaps between new and old concrete, to form watertight plasticity colloid. This product passed ministry-level appraisal in Beijing in June 1988, won the 1991 Technology Achievement Award, was given the certificates of qualified products and recognized nationally. This kind of product opens up a new road for solving the gap leakage problem in concrete construction. Product quality has reached world leading level.

Characteristics: Gray putty-like gel, weather resistant, anti-aging, anti-leaking, erosion resistant, simple operation amd low cost etc. 

Features: This product has the effect of “prevent water by water”. Slow expansion speed, the expansion rate after soaking 186h ≤ 50% of the max expansion rate. Convenient for construction, competitive price, and non-toxic,non-pollution, no dissolved matter separating out in long time soaking. The biggest difference with other waterstop strips is its hydrophilic expansion property won’t lose after long-term repeated expansion.  
   

Main usages: PN (BW) waterstop strip is a kind of newest, best anti-seeping material used in underground construction works, waters, traffic tunnel, power plant cooling towers, municipal water supply and drainage etc concrete construction projects, which completely resolves the around seepage problems caused by friction between rubber and steel waterstop belt.
