Expansion waterstop when encountering water-遇水膨胀止水带

Water swelling waterstop usage:

Water swelling rubber waterstops can be widely used in various types of concrete structures, such as retaining dams, reservoirs, subways, culverts, tunnels, and other underground projects. In some construction projects, due to the inability to continuously cast, deformation of the foundation, or thermal expansion and contraction of concrete components caused by temperature changes, deformation joints and construction joints are often left during casting. The leakage prevention problem of these joints needs to be solved by using rubber waterstops at the deformation joints, which can prevent groundwater or external water from leaking into the building structure, It can also prevent water leakage from the building to the outside.

Characteristics of water swelling waterstop:

(1) The water swelling rubber waterstop has an advanced waterproof line design, which expands on its own after encountering water, making it closer to the concrete and achieving better water stopping effect.

(2) The cross-section of the waterstop adopts a non equal thickness structure, which is divided into a strong zone, a waterproof zone, and an installation zone to ensure that all parts are evenly and reasonably stressed.

(3) Adding installation holes in the installation area can facilitate fixation with adjacent steel bars without displacement. Convenient construction and reliable positioning and installation.
