EPS15 Geofoam was used on this project for Nunez community College in Chalmette, LA. A total of 413 blocks of EPS15 Geofoam 16” x 48” x 96” were used as void fill between grade beams under a structural slab due to poor existing soil conditions. EPS Geofoam is available in different densities for use as structural and nonstructural void fill.
