Geofoam is the perfect material to stabilize slopes of varying degrees
Lightweight fill is favored by geotechnical engineers for mass reduction and minimizing gravitational driving forces. In the past, lightweight fills were primarily comprised of cinders, chipped bark, dried peat, sawdust, and cellular concrete. In fact, seashells, shredded tires, and slag were also used. Today, geotechnical engineers are partial to EPS geofoam. Geofoam is upwards of 50 times lighter than other options, making it perfect for slope stabilization. Geofoam’s merits in the context of slope stabilization also include its comparably clean construction near waterways, minimal traffic impact, enhancing right-of-way and comparably less labor/maintenance as time progresses. Geofoam’s density is upwards of 100 times less than that of soil. There is no need to alter the geometry of the final slope when geofoam is used.
