Joints formed between adjacent concrete pours and where mechanical elements penetrate the concrete are the most likely points of water ingress into below-grade concrete structures. To prevent this from happening, waterstops are usually used and installed at every joint.
Waterstops are an essential element of the general waterproofing design to protect below-grade portions of any concrete structure. These products’ use in construction joints is a good design practice for building foundations, with or without a positive-side waterproofing membrane. In other words, the waterstop can be a belt-and-suspenders approach to provide a dry structure.
PVC waterstop, being installed in concrete joints, serves as a constant watertight diaphragm to prevent any ingress of liquids into construction joints. PVC Waterstops are flexible and designed for expansion or contraction joints; meanwhile, they can accommodate sideways and transverse movements which make it capable to suit the moving joints. Furthermore, the PVC waterstop are extruded from an elastomeric plastic material including high grade polyvinyl chloride, special resin and some chemical additives such as plasticizers and stabilizers. This engineered material makes PVC waterstops unsurpassed with a variety of features and benefits.
