Soil Substitute

Expanded polystyrene (EPS) foam has been used in geotechnical applications for more than 30 years. The extraordinary properties of EPS make it a great choice for use as a slope stabilizer, retaining wall backfill, road embankments, or pavement insulation, to name a few. EPS Geofoam has many specific advantages for use as a soil substitute, being only 1% the weight of soil and rock and less than 10% the weight of other lightweight fill alternatives. Lightweight, low density, thermal insulation value, compressive strength, long life performance, and low cost are all important when planning a geotechnical application, making Geofoam an optimum choice.

ICA can manufacture Geofoam in densities of .75 PCF to 2.85 PCF, with or without recycled content. Although not necessary, an insect repellent can be incorporated into the EPS foam if so specified. Generally, EPS geofoam blocks are requested in full billet sizes, i.e. 36 x 48 x 96, but can be custom cut to your specifications. ICA-GEOFOAM meets or exceeds the requirements of ASTM D6817, Standard Specification for Rigid Cellular Polystyrene Geofoam.

ICA has recognized the exceptional value of this multifunctional EPS foam product which has been used abroad for many years and is excited about its increased awareness and growing applications. Operating at the forefront, ICA worked closely with Dr. Dawit Negussey, the founding director of the Geofoam Research Center (GRC), at Syracuse University in 1997. GRC continues to be the leader in developing the standards and performance verifications of geofoam projects.
