Geofoam – Lightweight Fill for Geotechnical Use
Benchmark Foam, Inc. manufactures Geofoam, a closed-cell engineered, expanded polystyrene (EPS) product used as a lightweight fill material in efficient and multi-purpose applications in geotechnical operations.
Geofoam Applications and Benefits
Geofoam is used to solve subgrade instability and unpredictable load-bearing scenarios. It provides an exceptionally light weight of 50-100 times compared to conventional fill materials, making Geofoam perfect for several applications, including:
- Reduction of Settlements: Geofoam reduces settlements under different soil and rock conditions; it is, therefore, very important in works whose major concern is the mitigation of ground settlement.
- Minimizing Lateral Pressures on Retaining Walls: The lightweight reduces some of the lateral pressures that impact retaining walls, improving overall stability and performance.
- Slope Stability: Geofoam helps stabilize slopes by providing a solid base that prevents slope failure, especially in undesirable terrain.
- Embankments on Unstable Soils: Geofoam enables the safe construction of embankments on unstable soil conditions by providing structural support and reducing overall weight.
- Highway Insulation and Bridge Abutments: Geofoam’s insulating properties allow It to be effectively used in highway construction and bridge abutments, ensuring longevity and durability in such crucial infrastructure works.
- Frost Protection: Geofoam is a very good insulating material against frost damage that occurs due to frosting in various construction applications.
- Lightweight Void Fill: Due to its light weight and ease of installation, Geofoam is irreplaceable when filling voids and spaces in construction projects of any kind.
- Tunnel Projects and Underpasses: Geofoam provides reliable support in underground construction projects for improved stability and safety.

Environmental Considerations
Apart from its excellent performance attributes, Geofoam also addresses environmental concerns. Geofoam contains no CFCs, HCFCs, or other known ozone-depleting substances, making it an environmentally friendly and sustainable material.
Since it is inert and non-nutritive, it does not decompose, decay, or produce unwanted gases or leachates. More importantly, Geofoam can be recycled—meaning that it fits into environmentally sensitive construction.
