What do builders typically use to create foundations in flood-prone areas?

Builders typically use piers or stilts to create foundations in flood-prone areas because this elevates the structure above potential floodwaters. By raising the living space and critical utilities above the expected flood elevation, the risk of water damage is significantly reduced. This method helps ensure that homes remain safe and intact during flood events.

Piers or stilts provide a sturdy, elevated foundation that can withstand water flow and pressure, making it a preferable choice in areas where flooding is a concern. This technique also allows for better drainage and can be advantageous for maintaining the structural integrity of a building over time, especially in regions prone to heavy rains and rising water levels.
