Flooding Prevention and Restoration: What Homeowners Need to Know
While it is not possible to fully eliminate the chances of flooding in the home, there are steps that can be taken to help reduce the chances of experiencing a flood or at the very least to minimize the amount of water that could affect the home. Extend the downspouts at least 4-6 feet away from the foundation or into a subsurface drain that runs out to the edge of the property, preferably downhill. Grade the soil to slope away from the foundation, roughly ½” per foot for at least 10 feet. This will help to direct water away from the foundation.
Installation of a French drain system can also help to direct surface water away from the foundation. Proper installation of a sump pump either in the basement or in the crawlspace will also help mitigate water intrusion.
Flood repair and restoration work can be very expensive, costing up to tens of thousands of dollars. While not guaranteed to prevent flooding these simple steps will help to minimize water around the house and improve the overall quality and comfort of the home.
