Waterstops are static seals installed between joints of an concrete structures to avoid the passage water or another fluids. The waterstop is baked into the concrete or across and/or along the joint. As a way to select the right waterstop for your application there are many items to consider. Such as, the dwelling type, joint type, joint movement type, chemical containment requirements, and the means for securing the waterstop in position (hog rings, grommets, etc.)

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

Features

Waterstops utilize techniques during installation that force seals to embed in the concrete. In some applications, it’s important to repel water and liquids entirely. Special circumstances require protection against liquids motionless at night barrier created by the waterstop. This feature is owned by being forced to keep solvents, hot petroleum oils and chemicals from making its way past the seal itself. Capabilities include alternative physical forms for example strips. A strip can perform covering a huge area when ordered in large rolls or pastes.

Applications

Waterstops are necessary for construction projects where concrete is utilized to retain water or exclude it. These kinds 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 along with other types of refineries

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

Basements and concrete foundations for homes along with other buildings

Specifications

Specifications are created available in the following four areas:

Structure type

Joint type application

Joint movement requirements

Chemical containment requirements
