Design professionals are increasingly choosing geosynthetics like expanded polystyrene (EPS) geofoam as a lightweight fill material in infrastructure and building applications. The material is about 100 times lighter than traditional fills, yet is strong enough to support pavements carrying jumbo jets. EPS geofoam is durable, moisture-resistant, and, unlike other fills, has predictable stress/strain curves. The Federal Highway Administration (FHWA), state and local jurisdictions, and private engineering firms have frequently specified EPS geofoam for soft soil remediation, lateral load reduction upon retaining structures, slope stabilization, buried utility protection, and structural void fill.
