When most of us think about concrete, we consider it to be an impenetrable barrier. What most of us don't realize, however, is that concrete is actually a very porous material that will allow moisture to pass through it readily. Because we use concrete and concrete products whenever we build our homes in the foundation or as a walkway or patio, it may be necessary for us to do some concrete waterproofing in order to make sure that water can not pass through. After all, the last thing that we would want to have happen is for moisture to creep into our basement and either damage the walls or cause a mold problem within our home.
The best time for concrete waterproofing to take place is whenever the home is first being built. The reason why this is the case is because the outside of the walls are exposed and it is easy to waterproof them at this time. The concrete waterproofing that goes on the outside of your foundation walls is much different than the type that goes on the inside. Typically, a membrane of some sort is spread onto the outside of the wall, such as a tar like substance. You would not want to put this on the inside of your basement walls as it would be rather messy to deal with, especially if you live in this area of your home. It may also put off some fumes that would creep up in your home and may cause you to get sick.
Concrete waterproofing on the inside of the walls is also possible if the outside was not properly taken care of. This is usually done by means of putting some waterproofing paint on the inside of the walls, after any mold or mildew has been removed. It helps to keep the moisture from coming through into the basement, although it will still come into the concrete.
Regardless of the type of concrete waterproofing that you have on your home, you may still want to run a dehumidifier in your basement or crawlspace in order to keep the moisture out of the air. Because this area of your home is underground, it naturally collects moisture and that can cause a problem in the upstairs area of your home as well. Running a dehumidifier will effectively take care of any of these moisture problems that are not corrected by the concrete waterproofing on the walls themselves.
