Waterstops are static seals installed between joints of your concrete structures to stop the passage water or another fluids. The waterstop is embedded in the concrete or across and/or across the joint. So that you can select the best waterstop for your application there are numerous facts to consider. Such as, the framework type, joint type, joint movement type, chemical containment requirements, and also the way of 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 made concrete in the 1930s, it became predominant because the most used material in new construction. Due to the porous joints created when dispensing concrete in sections, the need for waterstops was immediately apparent. PVC was the predominant option for waterstops from the 1940s and continued for many years and is still the commonest waterstop material.
Waterstops utilize techniques during installation that force seals to embed in the concrete. In a few applications, it is vital to repel water and liquids entirely. Special circumstances require protection against liquids from moving beyond the barrier produced by the waterstop. This feature is associated with needing to keep solvents, hot petroleum oils and chemicals from making its well past the seal itself. Capabilities include alternative physical forms like strips. A strip is capable of doing covering a huge area when ordered in large rolls or pastes.
Waterstops are crucial for construction projects where concrete is used 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 along with other types 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 Specifications
Specifications are manufactured available in these four areas:
Structure type Joint type application Joint movement requirements Chemical containment requirements
