GEOFOAM

Expanded polystyrene (EPS) foam for geotechnical applications

What is Geofoam?

Expanded polystyrene (EPS) foam has been used as Geofoam in geotechnical applications for more than 30 years. The extraordinary properties of EPS make it a great choice for use as a slope stabilizer, retaining wall backfill, road embankments, or pavement insulation, to name a few. EPS foam has many specific advantages for use as a soil substitute, being only 1% the weight of soil and rock and less than 10% the weight of other lightweight fill alternatives.

There are many unique attributes that make Geofoam an optimum choice when planning geotechnical projects:

• Lightweight
• Low Density
• Thermal Insulation Value
• Compressive Strength
• Long Life Performance
• Reduced Construction Time
• Lower Construction Cost
• Stability
• Limited Water Absorption
• Ease of Handling

ICA can manufacture Geofoam blocks in densities of .75 PCF to 2.85 PCF, with or without recycled content. Although not necessary, an insect repellent can be incorporated into the EPS foam if so specified. Generally, EPS blocks are requested in full billet sizes, i.e. 36 x 48 x 96, but can be custom cut to your specifications. ICA-GEOFOAM meets or exceeds the requirements of ASTM D6817, Standard Specification for Rigid Cellular Polystyrene Geofoam.

ICA has long recognized the exceptional value of this multifunctional EPS foam product which has been used abroad for many years. We are excited about its increased awareness and growing applications. Operating at the forefront, ICA worked closely with Dr. Dawit Negussey, the founding director of the Geofoam Research Center (GRC), at Syracuse University in 1997. GRC continues to be the leader in developing the standards and performance verifications of Geofoam projects.

Geofoam in Green Roofs

The benefits of installing a green roof are both environmental and economical. Proper materials and installation are important. The lightweight and versatile characteristics of Geofoam make it a popular choice for insulation in green roof systems. Quality insulation is a critical layer in this sprouting business.

See how Geofoam makes a large green roof possible on a parking deck in Chicago – Maggie Daley Park.
