TYPICAL PHYSICAL PROPERTIES OF EPS GEOFOAM
Explanation of Geofoam
EPS Geofoam is a cellular plastic material that is strong, but has very low density (1% of traditional earth materials.) It is manufactured in block form and meets ASTM D6817, "Standard Specification for Rigid, Cellular Polystyrene Geofoam." EPS Geofoam is available in a range of densities to provide control of structural integrity and cost effectiveness. The information given below is deemed to be timely, accurate, and reliable for the use of EPS Geofoam. Each project using EPS Geofoam should be designed by a professional engineer. The engineer of project specifications should be consulted to determine the ASTM D6817 Type required for your project loading conditions.
