Rubber and PVC Waterstop
Divided by material, there are usually rubber waterstop and PVC waterstop. Some buildings cannot be poured continuously, or the ground is deformed or affected by the temperature environment. These phenomena can cause thermal expansion and contraction of concrete elements. Therefore, deformation joints need to be left, and waterstops need to be left in these gaps. It prevents water leakage and acts as a shock absorber. This can ensure the service life of engineering buildings.
