Mother Nature can be unpredictable at times. Places that don’t typically flood can be subjected to freak accidents and events that devastate an area. Homes might be severely damaged or destroyed in the event of one of these once in a lifetime storms or events. Whether you are in a flood zone or not, you should take steps to make sure your home is flood-proofed because you just never know.
Flood proofing reduces repair costs and loss of property value. It also protects your family from hazards like mold, sewage, and electrical issues. Floods can be devastating, but it is possible to limit the damage.
1. Elevate Electrical Systems
Raise electrical outlets, switches, circuit breakers, and appliances above the flood level. While you can’t technically predict the flood level, if you are in a flood zone, check with FEMA. They will have information about the likely flood level. Place outlets above that by several inches. This will prevent electrical damage and reduce the risk of electrocution during flooding.
2. Install Flood Vents
Add vents to your foundation walls to allow water to flow through rather than build pressure. This reduces structural damage by equalizing water pressure on both sides of the walls.
3. Use Water-Resistant Materials
Opt for tile, concrete, or water-resistant flooring and wall materials in vulnerable areas. This minimizes damage and makes cleanup easier.
4. Slope Landscaping Away from the House
Grade the yard so water flows away from the foundation. This prevents pooling and water intrusion into the basement or crawl spaces.
5. Install Sump Pumps with Backup Power
Place a sump pump in the basement or lowest point of the property with a battery or generator backup. Sump pumps drain water quickly during flooding, even in power outages.
6. Seal Foundation Cracks
Use hydraulic cement or waterproof sealant to fill cracks in walls and foundations. Sealing the cracks prevents water seepage through small openings.
7. Elevate HVAC Equipment
Place furnaces, water heaters, and air conditioning units on platforms above the expected flood level. You can reduce repair costs and keep essential systems functional.
8. Install Backflow Valves
Add one-way valves to your sewer line to prevent sewage from backing up into your home. This will stop wastewater from entering during heavy rains or flooding.
9. Use Flood Barriers
Set up removable barriers, sandbags, or permanent flood walls around vulnerable entry points. You’ll want to block water from entering doors, windows, and garage areas if possible.
10. Raise the Building
Elevate your home or key parts of it above the base flood elevation (BFE) using stilts or pilings. This ensures the main living areas are safe from floodwaters.
11. Create a Rain Garden
Plant a depression with water-absorbent plants to catch and soak up runoff. You can reduce surface water pooling and help manage stormwater naturally.
12. Install Permeable Pavers
Replace traditional driveways and walkways with permeable materials that allow water to soak through. This minimizes runoff and reduces water pooling.
13. Construct a Retaining Wall
Build a water-resistant retaining wall around the property or specific areas. You can protect against minor flooding and channel water away from the home.
14. Maintain Gutters and Downspouts
Regularly clean gutters and ensure downspouts direct water at least 10 feet away from the foundation. Prevents roof water from pooling around the house.
15. Install Flood Sensors
Use water detection alarms in basements or low-lying areas. Provides early warning to take action and minimize damage.
