Waterstops are static seals installed between joints of an concrete structures to avoid the passage of water and other fluids. The waterstop is baked into the concrete or across and/or across the joint. To be able to pick the right waterstop to the application there are lots of things to consider. Such as, the structure type, joint type, joint movement type, chemical containment requirements, and the way for securing the waterstop in place (hog rings, grommets, etc.)

Concrete waterstops rose to prominence as concrete use had become the standard choice in residential and commercial construction in the mid-20th century. After concrete bridges started dotting the map noisy . 1900s as well as the Hoover and Grand Coulee dams were built from concrete within the 1930s, it became predominant since the most used material in new construction. As a result of porous joints created when dispensing concrete in sections, the requirement for waterstops was immediately apparent. PVC was the predominant option for waterstops from 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 in the concrete. In certain applications, it is necessary to repel water and liquids entirely. Special circumstances require the prevention of liquids motionless beyond the barrier manufactured by the waterstop. This feature is owned by needing to keep solvents, hot petroleum oils and chemicals from making its way past the seal itself. Functions include alternative physical forms such as strips. A strip can perform covering a vast area when bought in large rolls or pastes.

Applications

Waterstops are necessary for construction projects where concrete is used to retain water or exclude it. These types 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 as well as other buildings
