Placement of geofoam behind retaining structures and below-grade walls can offer advantages of reduced lateral pressure, lower settlements, improved waterproofing and better insulation. The central concept of using geofoam as a retaining structure backfill is to substitute as much of the soil in the active or at rest wedge with geofoam to the extent desired.

The finished grade behind the retaining structure can be developed with or without a load distribution slab or plastic sheeting cover above the top surface of the geofoam, as desired. An application scheme for a retaining wall or abutment backfill is shown below.
