Rain, Rain, Go Away
To protect your home from flood damage there are several options that can help. First, you should assess the risk of flooding in your area and your home specifically. Then decide what best fits your needs, such as installing a flood control system and applying sealants to any cracks in your home's foundation. Finally, make sure to check with your insurance agent to see if any additional coverage is needed.
Flood-Proofing to Protect Your Home
-If you're building a house in an area prone to flooding you can choose to build it on stilts or piers. Even an inch of water can lead to substantial damage so by raising your home above the flood level; it will significantly increase the protection of your home.
-Install foundation vents or a sump pump. Foundation vents allow flood water to flow through your home, rather than collecting inside. Of course this method would still cause water damage to the areas that water flows through. A more common option is a sump pump, they are frequently used to pump water out of basements where flooding happens regularly. Keep in mind that if you loose power in your home the sump pump will not work without a backup. You can purchase a sump pump with a battery backup, so that you can still protect your home from rising water, should the power go out.
-Apply coatings and sealants to your foundation, walls, windows and doorways will help prevent flood water from seeping into your home through cracks.
