Geofoam refers to block or planar rigid cellular foam polymeric material
used in geotechnical engineering applications. Geofoam has very low
density, good insulation, low hydraulic conductivity as well as strength
and deformation properties that complement soil behavior.
Geofoam has been
used successfully in different applications over a period of more than
25 years. Unless otherwise stated, research results and application histories
presented at this web site refer to expandable polystyrene (EPS) as geofoam.
