Geofoam has been used for decades in Europe, Canada and parts of the United States and has proven not to settle or deteriorate over time.

One advantage of EPS (expanded polystyrene) has over other fill materials is its resistance to water damage. Even if the site is below ground water, the strength of the EPS Geofoam is not compromised. The integrity of the Geofoam blocks remains unchanged when buried for years beneath soil and water.

The most common uses of Geofoam are as a lightweight fill and as insulation. Some specific applications of Geofoam are outlined below.

• Unstable Soil Substitute
• Roadbeds & Runways (pavement insulation)
• Retaining Walls
• Highway Clover Leaves
• Theatre Stadium Seating
