EPS 12 Geofoam was used as void fill between an existing slab and a raised slab for this yoga studio in Arlington, VA. There were two issues to deal with. The fill needed to be very lightweight and there was a maze of plumbing waste and supply lines to work around. Using EPS12 Geofoam, primarily in blocks 22-1/2” x 48” x 96” the contractor was able to fill the space while adding just over 1.3 lbs per square foot of Geofoam. An electric hot wire bow cutter was used to slab and trim the blocks as necessary to work around the plumbing.
