What is a back mounted rubber waterstop? In short, it is a waterstop made of rubber material, usually used with reinforced concrete structures. Its innovative feature is that its back has a bonding performance, which can be directly attached to the surface of concrete or other walls during construction, forming an effective watertight barrier. Compared with the traditional caulking or grouting waterstop, the back sticking rubber waterstop is easier and faster to install, especially suitable for complex structural gaps or large area waterproof needs. When designing and selecting the rubber waterstop with back sticking, its material should be considered first. Common rubber materials include natural rubber and synthetic rubber ..

1、 The basic concept and structure of the steel edge waterstop is a waterproof sealing belt made of rubber or elastic materials, usually with steel edges on one or both sides of the belt. Its core function is to prevent groundwater seepage and prevent water pressure from eroding the structure. The addition of steel edges not only enhances the overall rigidity of the waterstop, but also improves its durability and construction convenience. Generally speaking, steel edge waterstop consists of the following parts: main elastic sealing materials, steel edge structure and necessary connecting devices. The main elastic materials are mostly high-performance rubber or polymer materials with good elasticity and aging resistance ..
