To choose a waterstop that is suitable for your project&#;s waterproofing needs, it is vital to know the various product types and material compositions. Most varieties are manufactured exclusively for use in cast-in-place concrete construction joints, while some types can also be used with expansion joints. Moreover, there are some types of waterstops that must accommodate the expected lateral, transverse, and shear joint movements, as well as, the expected hydrostatic pressure.
Since the s, the most commonly used waterstop is PVC (Polyvinyl Chloride). Due to its strong and flexible features, these materials have been used due to the ease of welding and inherent resistance to groundwater and common waste water treatment chemicals. There are now myriad of metal, plastic, asphaltic, and hydrophilic materials, with differing compositions that are utilized to stop water ingress through joints in concrete structures.
More About Waterstop PVC
In general, PVC waterstop acts as a continuous watertight diaphragm to prevent any flow of liquids in constructions joints which are subject to hydrostatic pressure. These materials are designed for expansion or contraction joint. In addition to this, it can also accommodate lateral and transverse movements which make it capable to fit the moving joints.
Furthermore, waterstop PVC are extruded from an elastomeric plastic material such as high-grade polyvinyl chloride, special resin and some chemical additives including plasticizers and stabilizers. The high material makes PVC waterstops unsurpassed with a variety of features and benefits as shown follow.

Waterstop-Strip is a strip applied hydrophilic rubber swelling waterstop for use in all kinds of cast-in-place concrete construction joints, as well as steel, concrete and thick-walled PVC (minimum 1/8&#;) pipe penetrations. When exposed to water, the rubber expands, creating a compression seal within the joint or pipe penetration, blocking the passage of water.
