For more than 30 years, geotechnical engineers have specified Expanded Polystyrene (EPS) Geofoam for numerous geotechnical applications worldwide. Engineers have long recognized the utility of lightweight fill to reduce mass and associated gravitational driving forces.

Geofoam EPS is a closed cell, light weight, low density foamed plastic fill material. Geofoam is used where soil and construction conditions do not allow for heavier conventional fill materials such as soil, sand, gravel etc. The density of Geofoam is 50 to 100 times lower than soils.

Geofoam EPS is an inert, organic material produced from petroleum and natural gas byproducts. EPS does not contain ozone depleting chloroflurorocarbons (CFC’s) or hydrochloroflurorocarbons (HCFC’s). EPS provides no nutritive value to plants, animals, or microorganisms. It will not rot, and is highly resistant to mold and mildew.

ABT Foam, LLC manufactures Geofoam EPS billet sizes ranging from a maximum of 36” thick x 48” wide x 192” long trimmed, and half billets 36” thick x 48” wide x 96” long trimmed. Other sizes and shapes are available to meet the demand of today’s construction needs and specifications. Full size billets can be provided untrimmed leaving the natural molding skin in place.

ABT Foam produces Geofoam EPS from the light density EPS 12 at 0.70 density minimum, to the heavier EPS 29 with a density of 1.80 minimum. For additional physical properties please see chart “Physical Property Requirements of RCPS Geofoam".

Typical Uses for Geofoam

  • Highway construction where unstable soil conditions prevent heavier fill materials
  • Highway embankments
  • Bridge abutments
  • Slope stabilization
  • Stadium seating fill
  • Theater and auditorium fill
  • Retaining wall structures and back fill
  • Planter and green roof top fill
