Some ways to keep your basement dry may seem rather obvious. Ideally your basement has a good surface grading to drain surface water away from the house. Exterior waterproofing and keeping wall cracks sealed are two other first-step methods. If you have tried these methods and still have water build-up problems in your basement, you may have to resort to other methods.
A sump pump is another common method of drying out a basement. Some professionals recommend this as a last resort, do-it-yourself attempt at water removal. There are two kinds of pumps available: submersible and water-powered. The submersible pump is electrically powered and is placed underground. They are more expensive than other pumps but are much quieter and can last for two-to-three times as long. The water-powered sump pump is fueled by your home's plumbing pressure. These pumps are usually slower at draining water but require no electricity and are often used during a power failure.
Many professionals install basement-waterproofing systems. If your home is at risk for consistent or extreme water build-up, it might be wise to seek the services of a competent professional. One professionally installed basement waterproofing system helps to alleviate underground water pressure and keeps the water from leaking into the basement. Other methods include the use of a polyurethane spray or foam. The foam acts as a very strong sealant and can repair cracks and leaks around basement walls and windows. Because the foam is extremely weather resistant, the treatment can last for a decade or longer.
