GeoTech TerraLite™ is the "Classic" Geofoam, with the added bonus of being manufactured from fire resistant bead and having "TIMBOR" added, which prevents insects from nesting in the material.

For the un-initiated, "Geofoam" describes large blocks (approx 3' x 4' x 8 or 16') of a synthetic material weighing from 0.75 pcf to 2 pcf, depending on the physical properties required. This extremely light weight fill material permits immediate construction over areas where the soil characteristics would normally require months of surcharging or other exotic treatments to raise it's strength. Examples of TerraLite™ Geofoam usage are:

• Highway, rail, or runway construction in areas of unstable soils
• Landscaping berms over structural slabs or unstable soils
• Backfill for building and retaining walls in areas of expansive or unstable soils
• Levys and Dams
• Large Fill-Jobs with unique requirements, such as quick turn around or low dust generation

This is a short specification for the use on projects requiring the use of TerraLite™ Geofoam.

This is a very comprehensive specification for use on projects requiring the use of TerraLite™ Geofoam. It includes more detail on the installation process and the use of a geomembrane. It can be saved as an ordinary TEXT document, and should be viewed and printed with a proportional font to preserve the formatting.
