    Waterstops are static seals installed between joints of the concrete structures to avoid the passage of water or other fluids. The waterstop is baked into the concrete or across and/or along the joint. As a way to pick the right waterstop for that application there are several things to consider. These include, the structure type, joint type, joint movement type, chemical containment requirements, and also the way of securing the waterstop set up (hog rings, grommets, etc.)

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


    Waterstops utilize techniques during installation that force seals to embed in the concrete. In most applications, it is vital to repel water and liquids entirely. Special circumstances need the prevention of liquids still beyond the barrier created by the waterstop. This feature is assigned to the need to keep solvents, hot petroleum oils and chemicals from making its well beyond the seal itself. Capabilities include alternative physical forms for example strips. A strip is capable of covering an enormous area when ordered in large rolls or pastes.


    Waterstops are necessary for construction projects where concrete is utilized to retain water or exclude it. Most of these 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 forms of refineries

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

    Basements and concrete foundations for homes as well as other buildings


    Specifications are produced accessible in these four areas:

    Structure type

    Joint type application

    Joint movement requirements

    Chemical containment requirements
