Our main products include:Waterproofing products as rubber waterstops,pvc water stops, Bentonite Waterstop; Bridge and road construction products as various Elastomeric bearings, bridge pot bearings, spherical bearings, bridge flexible equipment; Seismic isolation as lead rubber bearings, high damping rubber bearings, steel type seismic bearings and bridge expansion joint, Inflatable pipe plugs, etc.

The water expansion rubber gasket is mainly used for the waterproof of the bolt holes in the installation process of shield pipe.Using the water expansion rubber, it is used to strengthen the waterproof by using the double action of bolt compaction and rubber expansion.

Rubber water-stop rubber water stop is a natural rubber and various synthetic rubber as the main raw material, mixed with various additives and fillers, classics plasticate, mixing, pressing molding, the varieties and specifications, with bridge, mountain, p, u, z, b, t, h, e, q, etc.The water stop material has good flexibility, abrasion resistance, aging resistance and tear resistance, ability to adapt to the deformation, good waterproof performance, temperature range - 45 ¡æ ~ + 60 ¡æ.When the temperature exceeds 70 ¡æ, and rubber water-stop with strong oxidation or corroded by oil and other organic solvents, shall not use rubber water-stop.
