StarRGeoFoam is high-quality expanded polystyrene (EPS) product used for engineering and geotechnical fill applications. It works due to its low density, compared to that of traditional soil (which is approximately 75-120lbs/ft3). Due to its lightweight and physical properties, it is unaffected by normal weather, maintains its properties over time, and is easily transported to and around the site.

**StarGeofoam, meets or exceeds ASTM D6817.
