Whether you are constructing a house, a tunnel, a dam, a wastewater treatment plant or any other liquid retaining structure, it is important that you get the right waterstop material. In addition to the popular PVC waterstops, there are several other options that you may consider.

Metallic

Made from steel, bronze, lead and copper, metal-based waterstops are embedded the same way as PVC stops. However, metallic stops are much stronger and are therefore suitable for heavy construction projects, such as dams. They are likewise ideal for applications where the construction materials will be exposed to extreme chemicals or temperatures.

Urethane

Upon exposure to water, this hydrophilic compound swells up to 350 percent of its original volume, forming a compression which seals a concrete joint. This waterstop solution requires being kept completely dry prior to its application. Additionally, it needs to be left dry for at least 24 hours after application for it to cure. In the past, urethane application has been made easier using a caulking gun or strips.

PVC

This is available in various thicknesses, widths and sizes to suit the requirements of any construction project. The primary advantage of this category is the fact that they can be used in any weather condition, including wet and rainy days. They likewise last longer than other options.

Regardless of the type that you go for, the efficiency and durability of the waterstop will be determined on its installation. Most waterstops fail at the installation level where they are either not installed correctly or the concrete is poured too soon or carelessly. Hire a professional to fix it, so you can ensure absolute protection for your building.
