Different Methods Used In Concrete Waterproofing

Posted on: 30 March 2016

One of the most commonly used construction materials for both decorative as well as utilitarian applications is concrete. This material is sturdy and durable, thus making it an excellent choice for walls, driveways and more. However, concrete can acquire water damage in the form of flaking, chalking and cracking due to constant exposure to wet conditions. Since concrete is primarily used outdoors, it would be prudent to opt for concrete waterproofing to protect its structural integrity. There are various ways in which concrete contractors can waterproof your concrete for you, thus, preventing it from acquiring premature damage.

Crystalline waterproofing

This type of waterproofing becomes a permanent component of the concrete. The concrete contractors will mix the crystalline compound with water. When poured onto the concrete, there is a chemical reaction that enables the crystalline compound to create a multitude of crystals. These crystals will fill all the crevices, pores and hairline cracks present on the concrete's surface. Since the crystals produced become part of the concrete, you do not have to worry about your concrete losing its waterproofing down the road.

Sealers for concrete waterproofing

Another method that can be used for concrete waterproofing is sealers. There are two main options that your concrete contractors could choose. The first is the penetrative sealers that absorb right into the concrete by taking advantage of its pervious nature. These sealers cause a chemical reaction when they come into contact with the concrete, resulting in a barrier that will not allow any moisture through. The second type of sealers are the film sealers. As the name suggests, the concrete contractors will apply a film on the concrete that it impervious to water and any other types of liquids. Film sealers are typically used when waterproofing decorative concrete. They comes in various forms including polyurethane, acrylic and epoxy. Sealers need to be reapplied occasionally to keep the concrete waterproof. It should be noted though that penetrative sealers do not change the appearance of your concrete whereas film sealers do.

Membranes for concrete waterproofing

There are two forms of membranes that can be applied to your concrete to protect it from water damage. These are sheet-form membranes and liquid-form membranes. Sheet-form membranes are simply attached to the concrete to create a barrier against water. Liquid -form membranes can be trowelled, sprayed or rolled right onto the concrete surface. The liquid is then left to cure until it forms a rubber coating on the concrete.
