Features

Our water swelling rubber waterstop is a high-performance waterproof sealing material used to prevent leakage at joints of construction and civil structures. In contact with water rubber expands to 1-5 times from the initial volume, filling irregular cracks, holes and voids in the seams, creating a powerful contact pressure that provides complete leakproofness of the watertight effect.

Unlike conventional rubber materials, where structural displacement results in stitches falling outside the elastic range, this product can still continue to play a hydrocontainment role by increasing water intake, even if the structure is deformed, it can maintain stable water resistance.

The use of water expanding rubber as a water retaining material can not only reduce the use of the material, but also avoid the fatigue caused by the common elastic material due to excessive compression, which makes the watertight effect more durable and reliable and has excellent water, chemical and ageing resistance.

It is mainly used for the construction of panel stitches, deformation stitches, building stitches and watertight sealing between metal and prefabricated concrete structures. It is also widely used to seal pipeline openings, roof engineering interface, open pit design, underground interface, hydraulic and hydraulic structures and other civil works of watertight system.

Link to construction

Before filling the concrete, contact with moisture should be avoided. In order to ensure its reliable connection to concrete, the building surface must remain dry, clean and level.
