Waterstops are static seals installed between joints of the concrete structures to avoid the passage water and other fluids. The waterstop is a part of the concrete or across and/or over the joint. To be able to select the best waterstop for your application there are numerous facts to consider. For instance ,, the structure type, joint type, joint movement type, chemical containment requirements, along with the means for securing the waterstop in position (hog rings, grommets, etc.)

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

Features



Waterstops utilize techniques during installation that force seals to embed to the concrete. In some applications, it is necessary to repel water and liquids entirely. Special circumstances require protection against liquids from moving after dark barrier produced by the waterstop. This feature is a member of needing to keep solvents, hot petroleum oils and chemicals from making its way past the seal itself. Additional features include alternative physical forms such as strips. A strip is capable of covering a massive 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 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 as well as other kinds of refineries
Storage tanks, both above and underground, for liquids like fuel or chemicals
Basements and concrete foundations for houses along with other buildings
