BW water stop strip that swells when exposed to water

--d ---dd ! ->
() Waterstop strip is a new type of building waterproofing material with self-adhesive properties, which is synthesized from polymers, inorganic water-absorbing swelling materials, rubber and additives. When exposed to water, it can absorb water and expand in volume to squeeze the gaps between new and old concrete to form a water-impermeable plastic colloid. This product passed the ministerial appraisal in Beijing in June 1988 and won the 1991 Science and Technology Achievement Award and was issued a certificate to become a nationally recognized qualified product. This product creates a new way to solve the leakage problem of concrete construction gaps and fills a gap in waterproofing in my country. Product quality has reached the world's leading level.

< --d ---d --d ---dd ! Main uses
< --d ---d --d ---dd ! () Water stop strips are various The latest and most ideal material for anti-seepage and leakage prevention in construction joints of concrete engineering projects such as underground building construction projects, water conservancy projects, traffic tunnel projects, power plant cooling towers, municipal water supply and drainage, etc. completely solves the problem of rubber and steel plate waterstops. Friction can easily cause leakage problems.
< --d ---d --d ---dd ! Features of the water stop strip:
< --d ---d --d ---dd ! This product has It has the effect of water-stopping when immersed in water. It has a slow expansion speed. Its expansion rate is % of the maximum expansion rate when immersed in water. This product is easy to install and construct, is non-toxic and non-polluting. There is no precipitation of dissolved matter under long-term immersion in water, unlike other hydrophilic swelling water-stops. The biggest difference is that its hydrophilic swelling properties have not been lost after long-term repeated expansion.
