Repetitive flooding affects thousands of Louisiana homes and businesses. In this publication and its companion videotape, a procedure to demonstrate a non-invasive method to flood proofing is explained as it was demonstrated by a Michigan contractor. Special attention is given to adapting the technology for use in Louisiana’s floodplains.

A floodwall is a self-supporting barrier to floodwater. It may look like a garden wall or privacy fence, but it has more internal reinforcing and a more substantial foundation. This heavier construction keeps the wall from tipping or sliding. The foundation also blocks seepage of water under the wall. This publication includes information on the cost, considerations and construction of floodwalls.
