Our PVC sleeve design waterstop fittings are the most cost effective solution for eliminating weeping and leaks around pipe penetrations. These waterstops are a fraction of the cost of brass waterstop fittings and non-metallic, so no grounding is needed. When encased in concrete, these waterstops will create a hydrodynamic waterstop. PVC waterstop fittings are fast and easy to install all you do is simply prime and glue in place and make sure to wire floor fittings tight and level during floor pour.
