A lot of people think of basement waterproofing as putting a sealer on their basement walls. This method only tends to be helpful if you’re experiencing minor dampness on the walls and even then there’s no guarantee. Interior sealers tend to be ineffective because they are unable to handle the build-up of hydrostatic pressure that water exerts on a foundation. Ever try to push a ball into a pool of water? The pressure pushing the ball back is hydrostatic pressure. Remember how hard it is to hold the ball down? If you times that by a thousand you’ll have an idea of the stress your basement is under. So when water is under hundreds, if not thousands, of pounds of pressure, a sealer is not going to be capable of holding that water back. Getting a dry basement means doing one of two things: Exterior waterproofing or Interior Pressure Relief System.
(Note: These systems can be either full perimeter or partial depending on your needs.)
At Main Line Waterproofing we can explain the ins and outs of both these techniques and see which method, if either, is right for you.
