External adhesive waterstop

An external rubber waterstop is a type of waterstop. It is installed on the outer surface of concrete joints in underground structures. These joints are for deformation and settlement. It can adapt to concrete’s expansion and contraction. This is due to the waterstop’s elasticity and structure.

The back-fit rubber waterstop uses natural and synthetic rubbers as its main materials. It is mixed with various additives and fillers. After plastic refining, mixing, and pressing, it has many types. These include bridge type, mountain type, P type, U type, Z type, B type, T type, H type, E type, and Q type. The back-fit rubber waterstop can be classified into two types based on use. They are the buried rubber waterstop and the back-fit rubber waterstop.

The water stop material has:

• good elasticity, abrasion, aging, and tear resistance;

• strong adaptability to deformation;

• good waterproof performance;

• a temperature range of -45℃ to +60℃.

Do not use rubber waterstop when the temperature exceeds 70 ℃. Also, do not use it if it is oxidized or eroded by organic solvents, like oil. Back-fit rubber waterstop uses high-elasticity rubber. It deforms under various loads. This seals well and prevents water leaks in buildings. It also absorbs and buffers shocks.

Many engineering building designs have expansion requirements. They are between civil engineering and soil and water structures. There are also waterproof and shockproof issues. So, using and installing rubber waterstop solves the above problems. The product is mainly for foundation work and underground facilities. It’s for tunnel culverts, aqueducts, and water-retaining dams. It integrates with concrete structures at construction and deformation joints during concrete casting. This ensures the project’s service life.
