man installing PVC water stopAsk any construction expert and they'll tell you that concrete joints are vulnerable spots to cracks and leaks due to the interference of water on a concrete structure. When water penetrates a structure, the moist conditions favour the growth of mold and can compromise integrity. 

Fortunately, as formdirect.com.au and other experts noted, you can get water stops for your concrete joints to minimise the occurrence of such cracks. Here are the common types:

Urethane

When this compound is exposed to water, it swells to form a tight seal in the joints. You can apply this water stop using a gun or strips. However, they should be dry before application and require extra time to cure before you pour concrete.

Metallic

These water stops are mostly made of copper, steel, or bronze. Due to the nature of the constituent materials, these water stops are strong and useful in big construction projects. You can also use these water stops in applications that involve harsh chemicals and extreme temperatures.

Bentonite

This material is a clay compound and hence, qualifies to be a hydrophilic water stop. It's useful in sealing joints and fills even the tiniest of areas in concrete. You should ensure, however, that your compound is dry before application or else you'll compromise the strength of the joint. These water stops wear out fast when in areas with high moisture exposure and are suitable for areas that do not experience moisture.

PVC

You need to embed these water stops on both sides of concrete to create a barrier in the cracks. They come in different sizes, thicknesses, and widths to suit various applications. The greatest advantage of these water stops is that they're useful in multiple applications regardless of the prevailing conditions.

When building a concrete structure, the last thing you want is to experience cracks in its joints and affect the state of the entirety of the structure. Ensure that you use the most suitable water stops for your application for maximum protection.
