Many types of foundations are used to elevate buildings and homes. While the main portions of elevated buildings are above the basement flood elevation (BFE), the foundation and any enclosed areas below the BFE will be exposed to floodwater.
To address this concern, the NFIP regulations require that enclosure walls contain openings that will allow for the automatic entry and exit of floodwaters. By allowing floodwaters to pass through the opening, this will even out the water level on both sides of the walls, thereby reducing the potential for damage caused by a difference in hydrostatic pressure on different sides of the wall enclosure. Contact Kennedy and Sons Structural Solutions for all of your Huntsville foundation and flood vent installation needs.
If enclosure walls are not designed with openings to relieve the pressure of standing or slow-moving water against them (called hydrostatic loads), the walls can be damaged or break during a flood. If the walls are “load-bearing” walls that support the elevated building, failure of the walls may result in damage to, or collapse of, the building.
