Geofoam Applications Case Studies, Geofoam Research Center, Syracuse University.

EPS geofoam is a lightweight, rigid foam material that has been used around the world as lightweight fill, compressible inclusions, thermal insulation, and drainage. EPS geofoam is approximately 100 times lighter than most soil and at least 20 to 30 times lighter than other lightweight fill alternatives. The following are common geofoam application concepts.

Embankment Stabilization – Jewett County, NY

After several attempts failed to halt the embankment deterioration the option of replacing the soil with EPS geofoam in the upper portion of the embankment was determined to be the best solution. The link below shows how that was accomplished.
