Residential Real Estate Tips to Protect Shallow Flood

Residential Real Estate Tips to Protect Shallow Flood

Shallow flooding is defined as flooding with an average depth of one to three feet in areas where a clearly defined channel does not exist.  This can occur for a variety of natural or human-caused reasons.  Some areas of shallow flooding are identified on flood hazard maps – many are not. So it is even more important to take proactive steps to prevent damage to the property.

Even in areas where flood waters are less than few feet deep, a house can be severely damaged if water reaches the interior. The damage to walls and floors can be expensive to repair, and the house may be uninhabitable while repairs are underway.  Home owners, property owners, landlords, property managers and property management companies can protect a real estate property from shallow flooding by adding a waterproof veneer to the exterior walls and sealing all openings, including doors, to prevent the entry of water. The veneer can consist of a layer of brick backed by a waterproof membrane.

This project generally requires a licensed contractor.

  • What to expect:
    • Before the veneer is applied, the siding is removed and replaced with exterior grade plywood sheathing.
    • If necessary, the existing foundation footing is extended to support the veneer material.
    • Changes will be made to the interior walls as well so that they will resist moisture damage.
    • Standard batt insulation is replaced with washable closed-cell foam insulation
    • Any wood blocking added inside the wall cavity will be made of exterior grade lumber.
  • Is this project right for your home?
    • Adding a waterproof veneer is appropriate in areas where the flood depth is less than 2 feet.
    • Greater flood depths can put pressure on the walls and cause damage.
    • If greater flood depths are expected, consult with a licensed civil or structural engineer before using this method.
    • If your house is flooded by groundwater entering through the floor, this method will not be effective.
    • If your house is being remodeled or repaired, consider having the veneer added at that time for save money.
