Basement Waterproofing FAQs
Hydrostatic pressure is caused when water pressure builds up outside a foundation. The weight of the water pushes downward until it finds the path of least resistance, and since a basement is nothing but a hole in the ground it is easy to see why it would come in the small seam at the floor / wall seam. It is usually recommended to discharge the water at least 10 feet or more away from the foundation. We accomplish this by installing an anti-freeze device and a solid pipe out to a yard drain. This pipe is buried underneath the sod and is hardly noticeable.
It depends on different factors such as the size of your basement, the type of foundation and the type of water problem you are experiencing. Generally the average 32ft x 24 ft basement will cost anywhere from $5000.00 to $10,000 depending on what type of equipment, battery backup system, etc. Financing options are available, and several things can be done to keep the cost down. For example some people will install just the sump pump system to start.
GrateDrain™ is a dual chamber system that is designed to accept ground water faster than any other drainage pipe on the market, yet it is placed just under the floor in front of the footer. This design allows ground water to only be pumped if water is going to come on the basement floor and doing so quickly when called upon to work.
GrateSump™ is our specially designed sump pump collection system. It was designed by someone who installed thousands of sump pump systems over the years. It is not as deep as other sump liners on the market and it will not encourage undermining of the foundation. We use our FastSump to pump the ground water out and away from the foundation.
