Building a new home? Congrats! While there are a few measures you can take to protect a home that’s already built from flooding, starting from scratch on a new construction poses some advantages. Here are a few things you can consider to protect your new construction from flooding:
Don’t build on floodplains
The only thing that cannot be changed once a home is built is its location. Building on a floodplain doesn’t only represent additional risks, but you will have to be extra cautious of flood-proofing your home. Flood insurance premiums will also be higher.
Evaluate a location’s flood risk by checking out FEMA’s flood map.
Raise your home on stilts or piers
Even an inch of flood water can damage your property. If you’re building your home – especially if you are in a floodplain – elevating your house on stilts will raise the house’s flood level.
Install foundation vents or a sump pump
Once there’s water in your home or basement, these two strategies minimize possible flood damage.
Flood water can put significant pressure on walls and basement windows. A foundation vent will allow water to flow through your home, relieving this pressure by providing an outlet and minimizing damage.
Sump pumps will pump water out of the basement. Consider that you will need to dig a hole in your basement, have electricity, and run pipes through a wall to install a sump pump. Plan for a sump pump early in your construction project to avoid additional costs and rework.
Install check valves on your pipes
To prevent a flooded sewage system from backing up into your home, make sure that all pipes entering your house have valves. Prefer gate valves because they provide a better seal against water pressure.
Apply coatings and sealants
Apply coating and sealants to your foundation, walls, windows and doorways to help prevent flood water from leaking into your house.
Raise electrical outlets and switches
To prevent electrical damage in the case of a flood, install outlets, switches, sockets, and circuit breakers at least one foot above flood level.
Make space between mulch and siding
Keep a space between mulch and siding to prevent wet mulch to rot the house’s siding, which in turn can lead to leaks.
Point downspouts away from your home
This might seem like an insignificant detail but if your gutter runoff is pointed toward the house, water may pool around the corners eventually creating leaks in the basement.
