    Waterstops are static seals installed between joints of a concrete structures in order to avoid the passage of water or another fluids. The waterstop is baked into the concrete or across and/or over the joint. To be able to select the best waterstop for the application there are several items to consider. For instance ,, the structure type, joint type, joint movement type, chemical containment requirements, as well as the means for securing the waterstop available (hog rings, grommets, etc.)

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

    Features

    Waterstops utilize techniques during installation that force seals to embed into the concrete. In a few applications, it is vital to repel water and liquids entirely. Special circumstances require prevention of liquids from moving at night barrier produced by the waterstop. This selection is assigned to needing to keep solvents, hot petroleum oils and chemicals from making its well past the seal itself. Characteristics include alternative physical forms including strips. A strip is capable of doing covering a vast area when purchased in large rolls or pastes.

    Applications

    Waterstops are crucial for construction projects where concrete is utilized to retain water or exclude it. These types of applications in residential, industrial and commercial 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 also other types of refineries

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

    Basements and concrete foundations for houses along with other buildings

    Specifications

    Specifications are created available in the next four areas:

    Structure type

    Joint type application

    Joint movement requirements

    Chemical containment requirements
