Geofoam Fill

Geofoam Fill

Lightweight Fill

Plastic geofoams have a density that is only one percent to two percent of the density of the soil, yet can be designed to be sufficiently strong enough to support road, rail and aircraft loading. Geofoam can be used as a lightweight fill over soft ground in embankment construction - a technique that does not require pre-loading and soil removal.

Thermal Insulation

Geofoams are very efficient thermal insulators. Considerable savings can be realized when Geofoam is used in pavement applications where frost-heave conditions are present. Geofoam can also be used for frost-protected shallow foundation without the need for a basement or crawl space to meet the frost-depth requirement.

Compressable Inclusion Plastic

Geofoam can be designed to compress readily to cushion the shock of earthquakes, reduce stress from expansive soils and fulfill a variety of similar roles.


Geofoams can be manufactured to have an inherent ability to drain ground water and ground-borne gases such as radon or methane.

Noise and Small-Amplitude Vibration Damping

Geofoam can dampen ground-borne vibrations from motor vehicles and trains.


Geofoam can be used as concrete foam-work and facing panels for mechanically stabilized earth walls (MSEW).
