China manufacturer good quality concrete project water expanding bar
Water expanding waterstop, is the general name of PN waterstop and PZ waterstop, both having the features of water expanding, water absorbent.
It is made from water expanding rubber, bentonite rubber, which has better sealing performance than common rubber.
When meet with water, the waterstop strip will deform, expanding, swelling and fill in the surface, gaps, holes and generate big contact pressure. So it can prevent seepage completely.
Expansion rate:
150%--600%
Popular sizes:
12x12mm, 15x15mm, 10x20mm, 15x20mm, 20z30mm, 20x50mm, 50x50mm etc.
Customized sizes are available.
