Geofoams can be used for thermal insulation, lightweight fill in earthworks, compressible inclusions to reduce earth pressures, vibration and noise damping and drainage. Geofoam is the generic name of the geosynthetic product category for foam materials used in geotechnical applications. The definition of geofoam adopted is any manufactured material (not limited to plastics) created by some expansion process that results in a foam with a texture of numerous closed, gas-filled cells. The cell walls are solid material although generally permeable to gases. This report includes: (1) an overview of foam materials and standards activities; (2) the geosynthetic functions that geofoams can provide; (3) the most commonly used geofoam materials, and the products made from them; (4) the geotechnically relevant material properties of geofoams; (5) a history of geofoam applications; (6) detailed suggestions for designing with geofoam; (7) recommendations for standards development and future research. There is an extensive bibliography.
