Special Characteristics

Good water-stopping effect: it has the elastic sealing water of rubber and the double sealing water stopping mechanism of its own volume expansion and water stop after water, and can resist water pressure of 2.5Mpa.

Good expansion: high expansion rate, reaching more than 220% or 400%.

Convenient construction: single component, glue, standard caulking gun can be used.

Construction tight & close: It can be firmly attached to the concrete surface regardless of whether the base surface is wet, smooth or rough.

Safe and environmentally friendly: safe, non-toxic, it is an environmentally friendly product in contact with drinking water.

Cost-effective: The performance is better than the traditional construction joint waterproof material, such as steel edge rubber water-stop glue or tape, the price is reasonable.
