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.Shape of water stop:

Bentonite waterstop with expanded metal
Bentonite waterstop with expanded metal is a new type water sealing product. The added expanded steel mesh (or nylon mesh as your request) effectively enhances the tensile strength of the waterstop and improves the overall construction quality.
Bentonite waterstop with grouting pipe
The perfect match of bentonite waterstops and grouting pipes extremely improve the performance of the water-proofing capability. Once the leakage of water occurs, you can plug the crack through pouring chemical grout into the pipe, instead of slotting and drilling a hole on the construction surface.
