GeoSpec® lightweight fill material is expanded polystyrene (EPS) geofoam used in ground fill applications where a lightweight fill material is required to reduce stresses on underlying or adjoining soils/structures. Traditional earth fill materials are more than 100 times heavier than GeoSpec, and can cause settling, erosion and instability of soils over time. EPS geofoam has been used in projects involving roads, bridge approach fills, embankments, levees, berms, foundations, landscaping, etc., worldwide for over 50 years.

GeoSpec fill material can be designed to support high compressive loads, but has a density less than 1% of traditional earth materials. It can be designed to meet a wide range of geotechnical engineering specifications with a typical density range of 11 kg/m3 (0.7 pcf) to 40 kg/m3 (2.5 pcf) providing a range of compressive resistance properties.

As part of Plasti-Fab’s dedication to Quality, Service and Expertise, Design assistance can be provided in selecting the required GeoSpec fill material for specific applications.
