What is geofoam used for?
EPS (Expanded Polystyrene) or “Geofoam” is gaining popularity as a widely acceptable and cost efficient construction insulation material. It 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.
What is geofoam insulation?
Geofoam – Structural Insulation InsulFoam® GF (EPS Geofoam) is a lightweight, geo-synthetic fill material used as an alternative to various fill-materials, as a soil stabilizer, and in various engineered applications.
Is geofoam water resistant?
EPS is popular for roofing and foundation applications because it will absorb very little water, which is an advantage in geofoam applications as well. It will continue to insulate and protect even when completely submerged.
How much does geofoam cost?
$55 to $100 per cubic yard
Recent cost estimates of geofoam vary from $55 to $100 per cubic yard, depending on a project’s required physical properties.
How strong is geofoam?
Specifications
| TYPE – ASTM D6817 | EPS12 | EPS29 |
|---|---|---|
| Compressive Strength, min., kPa at 1% | 15 | 75 |
| Compressive Strength min., kPa at 5% | 35 | 170 |
| Compressive Strength min., kPa at 10% | 40 | 200 |
| Flexural Strength, min., kpa | 69 | 345 |
What is geofoam made of?
What is it made from? EPS Geofoam 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.
Is geofoam eco friendly?
Under normal conditions, EPS geofoam is virtually maintenance-free. Because it is 98% to 99% air by volume, EPS geofoam is also a highly efficient thermal insulator. Unlike Styrofoam, however, EPS geofoam is 100% recyclable and environmentally friendly.
What weight can Geofoam support?
Q: How much weight can EPS Carry? ASTM C578 standard for EPS type I is 10psi or 1,440 pounds per square ft (1 square foot is equal to 144 square inches). One square inch of Type I EPS can support 10 pounds; however, set a one square foot board on the foam and it can support 1,440 pounds.
Is Geofoam biodegradable?
And, since using EPS geofoam can shorten construction time significantly, there’s less impact to the environment surrounding the project. In addition, EPS geofoam is not biodegradable. It will not leach into the ground over time, adversely effecting soil and groundwater quality.
What is Geofoam made of?
Is Geofoam porous?
Geofoam is a new porous light geo-material (e.g. cement treated soil with air foam) and has been widely employed to improve soft soil foundation of highway, airport and seaport, because of its light weight, low cost and high strength.
Is geofoam environmentally friendly?
EPS geofoam is one of the most environmentally responsible building materials you can use in your construction project. No potentially harmful greenhouse gases are used in the manufacturing process and the product doesn’t emit greenhouse gases.
What is geofoam and how it is useful?
What is Geofoam? According to the EPS Industry Alliance, Geofoam is defined as follows: “EPS Geofoam is used in geotechnical applications such as lightweight fill for construction on soft ground, for slope stabilization, and retaining wall or abutment backfill; as well as for roadway and runway sub-grade insulation and foundation insulation.”

Where to buy geofoam?
– Unstable Soil Substitute – Stadium Seating – Roadbeds & Runways – Retaining Walls – Highway Clover Leaves – Termite Resistance – Manufactured to meet ASTM D6817 (pg 4)
What is EPS concrete?
Expanded polystyrene (EPS) concrete (also known as EPScrete, EPS concrete or lightweight concrete) is a form of concrete known for its light weight made from cement and EPS (Expanded Polystyrene). It is a popular material for use in environmentally “green” homes. It has been used as road bedding, in soil or geo-stabilization projects and as sub-grading for railroad trackage.
