The duration of the waterproofing depends on several factors, including the amount of waterproofing product used, the weather and the severity of the initial damage. With all the different components, there is no fixed date, but most professionals will guarantee it for about ten years. When building a basement today, building codes require wood floor boards and sometimes wall studs to be made of pressure-treated wood to help resist water damage, but pressure treatment isn't a cure for everything. Stagnant water will eventually deform the treated wood members, causing them to swell, disfigure and even rot.

Treated wood takes longer to rot, but in the end it will. Basement waterproofing repairs are usually expensive and, depending on the cause of the dampness, could cost quite a lot. If a DIY repair is not suitable, a larger repair project may be necessary, but in most situations, the cost of basement repairs is an investment in the value of the home. Prices will vary depending on the scope of repairs and the current cost of labor.

Exterior waterproofing of the basement with drainage tiles also requires the installation of a sump pit where water will accumulate before being pumped to the surface through a sump pump. You can choose to install a sump pit inside, under the basement floor or outside the house, usually under a window well. Even if you don't need to completely waterproof your basement, you should at least take steps to protect your base from water. Install gutters and downspouts, and install downspout extensions that keep rain away from your home.

If your yard is not yet tilted away from the foundation with a minimum slope of 2 percent, incorporate topsoil to raise the ground level around the foundation. Relocate foundation plantations that require frequent watering, and install waterproof covers for window wells on basement windows that cannot be used for exit. Most waterproofing coatings dry in about three hours to allow additional layers. Waterproof coatings are the last line of defense for damp or leaking walls.

Most coatings have a nominal water pressure of 10 to 15 psi. These coatings are effective for handling wet walls of basement foundations. Do your socks get wet every time you go downstairs, do your children complain about the odd smell, or are there mold stains on the walls? Water in the basement is not always a cause for panic, but it can lead to serious structural problems if ignored. If your problems with leaks in the basement cannot be solved with a simple step, such as cleaning or repairing the gutters, you will have to consider a waterproofing solution for the basement.

There is no one-size-fits-all approach, it depends on what is causing the problem and the damage already caused. There is often a combination of factors at play and you'll need to employ more than one waterproofing technique for long-term effectiveness. If the foil test showed that water soaks into the basement walls and leaves them damp, seal the inside of the walls with a high-quality waterproof paint, such as DRYLOK White Extreme Waterproof (available from Home Depot).
