EPS geofoam is available in different material types. Thorough knowledge and understanding of the type being used on a EPS geofoam project is essential.
ASTM International has three standards pertaining to EPS geofoam.
- ASTM D6817 Standard Specification for Rigid Cellular Polystyrene Geofoam provides information on the physical properties and dimensions of expanded polystyrene intended for use as geofoam.
- ASTM D7180 Standard Guide for use of Expanded Polystyrene (EPS) Geofoam in Geotechnical Projects covers design considerations for the use of EPS in geotechnical applications.
- ASTM D7557 Standard Practice for Sampling of EPS Geofoam Specimens can be used for quality assurance.
