Applications - EPS Geofoam - Geofoam Information

EPS geofoam can be used as backfill behind retaining and buried structures to greatly reduce lateral pressures on the structure. Because the horizontal pressure acting on a retaining wall is proportional to the weight of the backfill, a less robust retaining structure is needed if the backfill soil in the active zone behind the retaining wall is replaced with EPS geofoam.Andrew Dawson's research works | University of Nottingham combining eps geofoam with geocell to reduce buried pipeThis paper reports full scale experiments, under simulated heavy traffic, of geocell and EPS (expanded polystyrene) geofoam block inclusions to mitigate the pressure on, and deformation of, shallow combining eps geofoam with geocell to reduce buried pipeAn experimental evaluation of geocell and EPS geofoam Their results confirmed the physical ones of Kim et al.
