Resistance to Termites, Mold and Meldew

Geofoam has been around for over 40 years. Manufacturers offer a warranty that can insure performance.

Size and Shape

Geofoam is produced in a block form and is easily positioned at the worksite.

  • Standard sizes:

    • 4' (1.2m) widths

    • 8' (2.4m) up to 16' (4.8m) lengths

    • 3" (75mm) to 30" (760mm) thickness.

  • Custom sizes and fabrication are available to meet any project requirement.

​​​​​Applications and Uses

In the construction industry, geofoam is the most adaptable lightweight material to work with. Common earth materials are heavy and can cause settlement, instability or lateral pressures. Some other fill materials such as formed concrete, waste tires, soils, wood fiber etc., have higher densities , are variable in their makeup and are not engineered, due to field execution variables. They also have limitations in handling and can be weather sensitive. 

Geofoam can be easily installed. It can arrive at a job site prefabricated and ready to place. Can be easily handled and installation is not weather sensitive.

Geofoam Properties

Exposure to Water and Water Vapor

Mechanical properties of geofoam are NOT affected by moisture. Exposure to water or water vapor does NOT cause the foam to swell.

Geofoam is made to give the best possible control for a project application: from design to material, cost and most importantly having control over the results. 

 Below are some advantages of using Geofoam:

  • Very lightweight compared to other fills.
  • Variety of types to meet different kinds of projects.
  • ​Cost efficient and effective
  • ​Long lasting, strong and stable
  • ​Easily shaped in field or can be supplied fabricated.
  • ​Protection against termites available.​

Geofoam stands up well to short term weather conditions during the installation process. The longer it sits in the sunlight, it can cause the color to change to yellow and can cause damage to the surface due to the ultraviolet light.

It is recommended to cover geofoam with opaque polyethylene film, tarps or similar material if it is stored outdoors.

Geofoam should be ballasted to prevent the product to be displaced by high water or wind conditions, both when being stored or during the installation process.

Foam plastics have been shown to become termite infested under certain exposure conditions. However, geofoam can be provided with resistance to termite infestation. Geofoam will not destroy and will not support mold or mildew growth.

Temperature Exposure / Flame Retardants

Geofoam is able to withstand rigors of temperature cycling, assuring long-term performance. Although flame retardants are used in the manufacture of geofoam to provide an important margin of safety, geofoam must be considered combustible. 

The maximum recommended long-term exposure for geofoam is 165 degrees fahrenheit (74 degrees celsius)
