PVC Waterstops

waterproofing-1BoMetals PVC Waterstop is a conventional waterstop that can be used in a variety of applications. The main usage is to prevent the passage of liquids in concrete joints in many different projects such as Dams, Tunnels, Water & Wastewater Treatment Plants, and other liquid retaining structures. BoMetals has become one of the American Owned Company leaders in the manufacturing of Waterstop, and we look forward to help you with your current and future projects.

BoMetals categorizes Waterstops by the type of concrete joints they seal. The characteristics of the joint are used to determine the differing demands on the Waterstops and their expected performance.
