Key features

Automatic Gap Filling: Traditional waterstops may leave leakage paths after structural movement or cracking; the water-swellable rubber expands upon water contact, actively filling gaps to help reduce

Water-Activated Self-Sealing: No additional grouting or coating is required; the material gradually expands upon water contact, generating sustained sealing pressure to help improve joint waterproofin

Wet-Site Suitability: Ideal for underground structures, tunnels, and water tanks where continuous moisture or water contact exists; the material swells when exposed to ambient water, helping lower lon

Product Q&A

Q:What is the working principle of water-swellable sealing strips?

Water-swellable sealing strips gradually increase in volume when exposed to water, filling gaps in concrete construction joints, pipe joints, and other areas to form a physical water-blocking layer and thus stop water from entering the site.

Q:What is the difference between finished product type (Blue red) and putty type (black)?

The pre-formed type (Blue red) is a pre-made material with a certain degree of hardness and elasticity. It maintains its shape after expansion and is suitable for regular and flat construction joints. The putty type (black) is a soft and sticky material that can adhere to irregular surfaces and is suitable for pipe joints, complex joints, and other similar areas.

Q:What products do you specialize in?

We specialize in high-quality rubber and plastic products for infrastructure projects, including: Bridge Bearings: Plate rubber bearings , spherical bearings , seismic isolation bearings Bridge.
