geofoam - expanded Polystyrene
Geofoam is commonly used for structural fill material, elevated slab applications, road construction and much more. Geofoam is extremely light weight and can withstand harsh conditions. Since Geofoam (Expanded Polystyrene) was introduced in the 1950s, it has been used in thousands upon thousands of various construction projects worldwide. EPS Geofoam has proven to be the material of choice to use in landfills, stabilizing slopes, bridge embankments, etc.

EPS is extremely light weight and can withstand harsh conditions. EPS was introduced as a building material in the 1950s, and has been used in thousands of projects worldwide.
EPS is different from the commonly known “Styrofoam” in several ways. While EPS Geofoam will mimic the physical characteristics of Extruded Polystyrene, or Styrofoam. The process of manufacturing is the key difference to create EPS a lighter and more sustainable product.
EPS is made from a material called polystyrene polymer. This polystyrene resin “bead” is delivered in large containers and fed into a hopper for manufacturing. It is essentially a thermoplastic that can be shaped and reshaped repeatedly. The Geofoam material is 100% recyclable and can be made using post consumed recycled content. Essentially, one can reheat it and reform it as many times as you’d like. Through a process called polymerization, polystyrene is created by applying heat and pressure within a mold. Depending on how much heat and pressure are added to the bead within the mold, different densities of Expanded Polystyrene or Geofoam can be produced.
