How to Fix a Wet Basement


Do you have a wet basement or does it flood during rainy weather? Most leaky basements could have been made watertight if good construction practices had been followed when the foundation was built.  Methods to control moisture include building an energy-efficient home with proper air-sealing, proper use of vapor barriers and vapor diffusion strategies. The entire building envelope, from the foundation to the roof, should be designed to not only prevent moisture entry, but also to allow any moisture which does enter your wet basement a means to escape.  A well-constructed basement should be just as effective in keeping out water as a swimming pool is in keeping it in! All homeowners should be knowledgeable on the current methods of how to fix a wet basement.

You can learn how to fix a wet basement by minimizing water leaks in a basement and in many cases the problem can be overcome completely. The first step to wet basement waterproofing is to locate the source of the water. There are several common places where water enters.  First is through wall cracks in your basement. Also there can be poor joint construction between the basement walls and the floor. Floor cracks are a common source of wet basements as are floor drains to the sewer. Some other wet basement solutions include using construction techniques which reduce the likelihood that warm, moist air will come in contact with cold surfaces, leading to condensation, mold growth, and rot. This includes controlling air movement and using vapor barriers on the warm side of walls and roofs.


Wet Basement Solutions

Obstructions, such as roofing gravel, leaves or other debris may block up the rain gutter, causing it to rust or leak. As a result, water will run down the side of the building and accumulate next to the wall, where it will slowly seep through into the basement. Sometimes the soil next to the wall slopes toward it, forming a pocket, where water collects after a hard rain. Gutters and downspouts for residential applications are available in various sizes which is important when implementing wet basement solutions. The larger the components, the more water the system can carry. Homes in areas subject to tropical storms often need even larger capacity systems. The appropriate size is determined by the number of inches of rain per hour expected from an intense downpour in the region where the house is located and the area and pitch of the house’s roof. A wet basement solution is to increase your gutter system’s capacity by using larger gutters and downspouts or by increasing the number of downspouts per length of gutter.

Another offender resulting in a wet basement is a clogged drain tile into which into which the downspout empties. The tile becomes clogged, causing the water to back up against the basement wall and seep through. Install protected drain tile at the footings of basement and crawl space walls, level or sloped to discharge to outside grade or to a sump pump as a good wet basement solution. The top of each drain tile pipe must always be below the bottom of the concrete slab or crawl space floor. Each pipe shall be surrounded with at least 6 in. of 1/2 to 3/4 in. washed or clean gravel. The gravel layer shall be fully wrapped with fabric cloth to prevent fouling of the drain tile. If a drain tile discharges to daylight and radon-resistant features are required, install a check valve at the drain tile outfall.
