EPS29 geofoam blocks were used to help level this mountain slope in Crested Bute, Colorado. Because the remote area was only accessible from switchback roads the geofoam blocks were first delivered to a staging area away from the site and then shuttled to the site using a small flatbed truck.
701 cubic yards of EPS29 geofoam in 4 foot x 8 foot blocks of varying thicknesses were used to fill a 40’ x 80’ patio area. The EPS 29 geofoam has a compression strength of 1,570 pounds per square foot (10.6 psi) at 1% deformation. The largest blocks measuring 3’ x 4’ x 8’ weighed just 173 pounds making them easily manageable with 2 people. After the 4 layers of geofoam were set in place a 4” concrete slab was installed.
EPS geofoam is often used for applications similar to this. Due the light weight of the geofoam it does not require any heavy earth moving equipment to set it in place. Any terracing of the slope can be done in tiers with lightweight equipment like a Bobcat. The lightweight blocks can be transported and installed by hand if necessary, and the different density of available blocks provide a compression strength suitable for any application.
