Dear Sir/Madam,

I am Minny from Hengshui Jingtong Rubber, a professional manufacturer of rubber waterstop solutions for concrete and infrastructure projects.​

We are pleased to introduce our PZ Waterstop, a new hydrophilic water-sealing product made of high-grade vulcanized rubber and additives. It swells upon water contact while retaining excellent rubber properties.

 

Compared with bentonite and butyl rubber waterstops, it features the following advantages:

 

• Expands 1–5 times when in contact with water to seal concrete gaps, holes and irregular surfaces. Remains effective even with joint displacement.

• Superior strength from cross-linked structure.

• Compact size with excellent water-swelling efficiency.

• No elastic fatigue under compression.

• Outstanding water, chemical and aging resistance.

              

Kindly find our product brochure attached. We would be glad to support you with samples or technical details if needed.

 

Best Regards,

Minny
