ack stick type rubber sealing strip

Back stick type rubber strip is mainly used for foundation engineering of cast-in-place concrete in construction joints when the deformation joints in concrete structure and become one of the facilities such as underground tunnel, culvert, aqueducts, dams, liquid storage structures and so on。 In the rubber waterstop, if it is found that the concrete pouring process in all or part of buried in the concrete pouring, there are many sharp stones and sharp head reinforced concrete, the tear strength of rubber and plastic tensile and low 3-5 times, once the waterstop punctured or torn, without external force gap will expand, so the waterstop positioning and concrete pouring process, should be note positioning methodAnd pouring pressure, so as to avoid the water stop is punctured。 Product of rubber seal, rubber belt, water swelling seal, two-component polysulfide sealant waterproof construction in the same industry have been gained in the assessment of the quality of an extension of the production of rubber, rubber waterstop, grouting, two-component polysulfide building waterproof sealant is widely used in water diversion process!

In the embedded rubber water stop belt is the middle of the hole in the installation of the waterstop is generally in the construction of the settlement joint, and the settlement is building the seam "deformation" distance in the event of settlement; therefore, if the sealing strip is "single" flat, the same kind of material the rubber anti deformation along the stretch of "no good round sections (because the circle with radian can be from" extending along the length to diameter difference between the semicircle "); also, the circular cross-sectional in the section of the settlement joint is double, than a" flat "layer can prevent a layer of damage" can still maintain the sealing effect.
