Geofoam
"...Plymouth Foam's EPS Geofoam is a cellular plastic produced from petroleum and natural gas by-products. Manufactured in block form, and in densities ranging from 1.00# - 2.00# per cubic foot, EPS is easily fabricated to finish dimensions at the factory and/or at the jobsite. PolyTec EPS Geofoam is third-party certified by Underwriters Laboratories and RADCO to assure product compliance with ASTM Standard C 578.
Plymouth Foam's EPS Geofoam has a very low density (1% the weight of earth fill) to provide engineered solutions in ground fill applications where weight reduction is desired to reduce the stresses exerted on poor load-bearing soils. Additionally, EPS Geofoam outperforms other alternative materials, such as foamed concrete, wood chips, waste tires, etc., is easy to handle and position during installation, and can be used year-round without weather related work stoppages...."
