- Foundation walls are constructed out of several materials such as poured concrete, cinder block, stone, and occasionally wood. The most common problem associated with foundation walls is moisture penetration.
- Approximately 60 percent of all basements and crawlspaces in this country suffer from some form of below ground wetness. Block foundations are especially vulnerable, with an 80 to 90 percent chance of leakage within the first 20 years”. It is estimated that 98 percent of all foundation walls will leak at some point during their life. It is rare that water penetration will cause structural damage, but a wet basement or crawlspace can be a major inconvenience causing damage to interior finishes, personal items and can lead to mold.
- Moisture problems in a home can be intermittent – leaking after every rain or, occurring only after heavy rain. Still, some homes may only leak during wind driven rains or during a spring thaw. In most cases, the damage that is caused gives no indication of frequency.
- It is estimated that 90 percent of all wet basement and crawlspace problems are caused by surface water (rain or snow) collecting around the building. Before investing thousands of dollars on a waterproofing system, it makes sense to get the water flowing away from the home first.
KEEP YOUR BASEMENT & CRAWLSPACE DRY!
Gutters and downspouts play an important role in diverting water away from the building.
- Clean the gutters and downspouts in the spring and fall (or as needed).
- Make sure that the gutters drain and are sloped towards the downspouts.
- Be sure the downspouts are extended well away from the foundation (4 to 6 feet is usually adequate).
- Improper grading around a home can be another factor in a wet basement. Re-grading the exterior landscaping to direct water away from the building rather than towards it, can be another effective solution to moisture problems. Ideally, the ground should slope down and away from the home at a rate of one inch per foot for the first six feet.
- Periodically inspect the soil around the perimeter of your home making sure that water is sloped away from the foundation.
- Any abnormal slanting, sloping or leaning of your floors, walls, or ceilings should be promptly investigated by a professional Contractor, A Foundation Contractor, or a Structural Engineer.
