Floodwalls [Image: Publication cover] 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. Wet Floodproofing [Image: Front page] The phrase “wet floodproofing” may sound like a contradiction, but it is the label used to refer to a collection of methods intended to reduce damage to a building when flooding occurs. This publication explains how wet floodproofing lets water into the building but protects the structure, contents and building systems independently.
