GEOFOAM

Soil Substitute

GEOFOAM

Soil Substitute

Expanded polystyrene foam has been used in geotechnical applications for more than 30 years.  The properties of EPS make it a good choice for use as a slope stabilizer, retaining wall backfill, road embankments, or pavement insulation.  EPS has many specific advantages for use as a soil substitute.  Light weight, low density, thermal insulation value, compressive strength, long life performance, and low cost are all important when planning a geotechnical application.

ICA can manufacture EPS Geofoam in densities of .75 PCF to 2.0 PCF, with or without recycled content.  Although not necessary, an insect repellant 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.
