Slope Stabilization

Geotechnical engineers recognize the validity of using expanded polystyrene (EPS) geofoam as lightweight fill to reduce mass and associated gravitational driving forces within sloped embankments. The detail below illustrates a typical slope stabilization application using GeoSpec® lightweight fill material. GeoSpec EPS geofoam with a density from 20 to 40 kg/m3 is up to 100 times lighter than in-place soil with a typical density of 2,100 kg/m3. This means that replacing in-place soil in an unstable slope with EPS geofoam can achieve a significant net reduction in driving force within the embankment.
