The Benefits of Waterproofing Concrete

We all have heard that concrete is like a sponge and soaks up everything, for example motor oil in a driveway. Stain/Waterproofing concrete to prevent motor oil from soaking into concrete is obvious because you don’t want to see a big dark stain, but what about waterproofing concrete to prevent water from soaking in? Water doesn’t leave a big ugly spot like oil does, so what is the benefit of waterproofing concrete. It turns out that water can damage concrete in more ways oil can, sure oil leaves an ugly stain, but water will soak deep down and begin to corrode the rebar causing areas of the concrete to spall off. Another reason why it is good to waterproof concrete, especially when areas are prone to have freezing rain, is that when water soaks into the concrete and then freezes it expands and will pit the concrete eventually the concrete will need to be replaced. So be sure to have your concrete waterproofed to prevent stains and also water damage.

Removing Tar Roofing & Installing Cementitious Waterproofing

Posted below is a recent video clip of some pictures of a recent concrete waterproofing job we completed. Our client had a concrete building with a built-up tar and gravel roof that he wanted to remove. They were planning on using the roof as a useable space consisting of a sitting area and areas that will be converted into a garden.

Stage one was to remove all of the tar from the roof, and install membrane c waterproofing cement. This is to get the general roof top waterproofed. The next stage will be to build cinder block planters and then add another coat of membrane c to the planters.
