Basement flooding can be a serious problem for some homeowners. A lot of damage can be done to your basement and its contents during a flood. However, there are steps that can be taken to minimize the potential damage. Making sure you are covered under your homeowners or other insurance policy is just one such measure.
Identify when the basement is flooding. Is your basement flooding the same time every year or at random intervals?
Identify where the water is entering the basement. If water is entering near the top of the basement in one location it could be due to an improperly sloped landscape that is angled towards the house. In order to solve the problem extend and redirect your downspouts and reshape the landscape around the home. Also, caulk any cracks where water may be entering.
If the whole wall is damp or water is coming in through multiple surfaces you may be missing a waterproofing membrane. You should probably consider hiring a contractor to install a membrane on the outside of your home. Also, you may consider using an internal sealant on the inside surface of the walls. The internal sealant is usually just painted on, making it easy to apply. However, you can not apply sealant to a finished basement. Note, these products require significant amounts of maintenance.
If water is entering near the foundation or through a floor drain you may want to consider installing a “French Drainage” system. These systems are installed at the base of the foundation. You should make sure these systems have a method for diverting water. The drain should empty into the primary storm drainage system, a retention pond, or other source. Also, install a sump pump with a battery or generator back up. Sump pumps should be tested once a year. You can test these by pouring buckets of water into the drainage hole in your basement floor until the pump turns on. If it does not turn on contact a professional for assistance.
Along with proper measures to avoid flooding, making sure your belongings are covered under your insurance policy is a good idea for people with finished basements or for people who use their basements for storage.
