Black color bentonite strip waterstop.
Bentonite waterstop is a kind of hydrophilic water sealing product coming with incomparable durability and higher water absorption no less than 300%. Unlike traditional clay based waterstops, this one utilizes rubber as base material to form a controlled, moisture active sealant - that means the bentonite waterstop will not expand to point losing much of integrity even being washed away by water during continually expansion.

Other bentonite waterstops for specific applications are also available in our company as shown follow:
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.
15 mm × 20 mm, 20 mm × 30 mm, 20 mm × 50 mm, 30 mm × 50 mm, 10 mm × 40 mm or others as your request.
