Types of Waterstops for Concrete Joints

Waterstop plays a vital role in waterproofing a concrete structure, especially the joints, the weakest part which is responsible for leakage of water or chemical liquids. Thus, waterstops are designed as a fluid-tight diaphragm embedded in or running along the joints to solve these problems. Chemical manufacturers in UAE offer various waterproofing materials in a wide range of sizes and shapes, the water stops are perfect for various types of applications including:


        Water and sewage disposal projects.
        Liquid containment.
        Dams, channels, tunnels and tanks.
        Box culverts and locks.
        Primary and secondary containment structures.
        Bridges and decks abutments.
        Wall and slabs.
        Basements and foundations

There is a wide variety of different waterstop for concrete joints which are available in the market, each with different strengths and weaknesses, which makes them appropriate for certain applications. Here’s some information on some of the most common:

PVC Waterstops
Experts say that PVC is used to waterproof concrete joints by applying it in both sides of the joint in order to create a physical barrier. There are a variety of thickness, widths, and sizes available to fit almost any construction joint. One of the main advantages waterstop pvc by Corrotech, is that they can be installed in virtually any conditions, including rainy and wet conditions. They also tend to last for a long time.

Urethane
Urethane is another hydrophilic compound. It swells to form a compression seal in concrete joints when exposed to water and grows about 350-percent its original volume. Urethane waterstops can also be embedded in strips or using a caulking gun, which makes them quicker and easier to install. They also need to be kept dry prior to application, but need an additional 24 hours to cure before the concrete is poured.

Metallic
Usually made from lead, bronze, copper or steel, metallic waterstops are applied almost the same with PVC waterstops. However, because they are stronger, they’re used in specialized applications like dams or heavy construction projects and also in projects where materials will be exposed to extreme temperatures or chemicals.


At Corrotech Construction Chemicals, they manufacture a wide range of waterstop materials including joint filler board, under their Corrostop series. Their waterproofing materials are often used at the time of casting for sealing of expansion and construction joints.
