Rubber waterstop

Product Details

Rubber waterstops and waterstop rubber are made of natural rubber and various synthetic rubbers as the main raw materials, mixed with various additives and fillers, and are molded through plasticizing, mixing, and pressing. They have many varieties and specifications, including bridge types. , mountain type, P type, U type, Z type, B type, T type, H type, E type, Q type, etc.

　　According to the usage, it can be classified into buried rubber waterstop and back-mounted rubber waterstop. This waterproof material has good elasticity, wear resistance, aging resistance and tear resistance, strong adaptability to deformation, and good waterproof performance. The temperature range is -45℃-+60℃. When the temperature exceeds 70℃, and Rubber waterstops must not be used when they are subject to strong oxidation or corrosion by solvents such as oil. It is generally used in the construction of basement exterior walls and post-pouring strips.

　　How to use:

　　Reliable fixing measures must be taken for rubber waterstops when tying steel bars and formwork. Prevent displacement when pouring concrete and ensure the correct position of the waterstop in the concrete.

　　Perforations can only be made in the permitted parts of the waterstop when fixing the waterstop. The effective waterproof part of the waterstop shall not be damaged.

　　Commonly used fixing methods include: fixing with additional steel bars; fixing with special clamps; fixing with lead wire and templates, etc. No matter what fixing method is used, the fixing method of the waterstop should be carried out according to the construction specifications required by the design and the waterstop must be accurately positioned without damaging the effective waterproof part of the waterstop to facilitate concrete pouring.

　　Classification

　　can be divided into: CB type rubber waterstop (embedded type with holes in the middle); CP type rubber waterstop (embedded type without holes in the middle); EB type rubber waterstop (externally attached type in the middle) Porous type); EP type rubber waterstop (externally attached type without holes in the middle).

　　According to the material, it can be divided into: natural rubber waterstop, neoprene waterstop, EPDM rubber waterstop.

　　According to the use situation, it can be divided into: middle-buried rubber waterstop and back-mounted rubber waterstop (external rubber waterstop), steel-edge rubber waterstop, water-expanding rubber waterstop, and flat-plate waterstop. Water hose.

　　Scope of application

　　Rubber waterstops are mainly used in foundation projects that are integrated with the concrete structure in construction joints and deformation joints when concrete is poured in place, such as underground facilities, tunnel culverts, water aqueducts, dams, liquid storage structures, etc.
