    Waterstops are static seals installed between joints of a concrete structures to stop the passage of water or any other fluids. The waterstop is baked into the concrete or across and/or down the joint. To be able to pick the best waterstop for the application there are numerous points to consider. Included in this are, the dwelling type, joint type, joint movement type, chemical containment requirements, and also the method for securing the waterstop available (hog rings, grommets, etc.)

    Concrete waterstops rose to prominence as concrete use took over as the standard choice in commercial and residential construction inside the mid-20th century. After concrete bridges started dotting the map in early 1900s and also the Hoover and Grand Coulee dams were produced concrete from the 1930s, it became predominant because the most used material in new construction. Due to the porous joints created when dispensing concrete in sections, the need for waterstops was immediately apparent. PVC was the predominant selection for waterstops from the 1940s and continued for several years and it is still the most typical waterstop material.


    Waterstops utilize techniques during installation that force seals to embed in the concrete. In certain applications, it is crucial to repel water and liquids entirely. Special circumstances have to have the protection against liquids from moving past the barrier created by the waterstop. This selection is assigned to having to keep solvents, hot petroleum oils and chemicals from making its well past the seal itself. Additional features include alternative physical forms such as strips. A strip is capable of doing covering a vast area when ordered in large rolls or pastes.


    Waterstops are crucial for construction projects where concrete is utilized to retain water or exclude it. These kind of applications in residential, commercial and industrial construction include:

    Dams and water reservoirs

    Canals, locks, aqueducts and culverts

    Bridges and tunnels

    Water and wastewater treatment facilities

    Sludge ponds

    Containment structures surrounding oil, chemical and other kinds of refineries

    Storage tanks, both above and underground, for liquids like fuel or chemicals

    Basements and concrete foundations for houses and also other buildings


    Specifications are made obtainable in the following four areas:

    Structure type

    Joint type application

    Joint movement requirements

    Chemical containment requirements
