The waterstop can withstand tension and torsion
The waterstop can withstand greater torque and tension, so as to ensure the galvanized steel edged rubber composite water stop not using effective deformation range of the rubber sealing belt in concrete, basically can overcome these shortcomings of pure rubber waterstop bridge. Also the steel edged rubber composite sealing belt also has a dual function, on the one hand can be extended way, slow water penetration rate on the other hand, galvanized steel and concrete edge has good adhesion, which can produce loosening and shedding phenomenon, improve the sealing effect. The steel edged rubber composite sealing belt with general telescopic rubber and composite galvanized steel side with both sides are formed. This mainly depends on the waterstop in the middle.In the plastic deformation between the concrete is compressed or stretched, and to seal the sealing effect. In general, concrete and rubber adhesion is poor, in the conventional construction, because the rubber is soft and elastic body, which is not easy to be cut in the concrete pouring, the concrete expansion joints, pull off. Often the rubber sealing belt will turn loose and fall off, resulting in the condition of high head pressure will produce leakage. For large deformation joint seam, the problem is more prominent.
