Description
InsulFoam® GF (Geofoam) is a high-performance, lightweight, geosynthetic fill material consisting of clised cell expanded polystyrene (EPS). Geofoam is the common industry term for InsulFoam GF and similar produts.
InsulFoam GF is manufactured from the same high-quality blocks as our InsulFoam brand insulations and meets or exceeds the requirements of ASTM D6817, Standard Specification for Rigid Cellular Polystyrene Geofoam. InsulFoam GF is manufactured in a common density range between .70 to 2.85 lb/ft³ (11.2-45.7 kg/m³) and is an ideal, lightweight fill alternative for many construction applications.
Uses
InsulFoam GF is commonly used in areas where unstable soil conditions exist and as an alternative to various fill materials. The unique load disbursement and lightweight characteristics of InsulFoam GF help to minimize any post-construction settling. InsulFoam GF is also used as backfill to reduce lateral earth pressure behind adjacent structures such as retaining walls. InsulFoam GF is successfully used in the following Engineered applications:
• Roads & Highways
• Bridge Approaches
• Retaining Walls
• Berms & Embankments
• Loading Docks & Ramps
• Landscaping
Advantages
Lightweight. With typical densities from .70 to 2.85 lb/ft³ (11.2 45.7 kg/m³ ), InsulFoam GF is significantly lighter than soil (approximately 120 lb/ft³). Cost-Effective. The lightweight nature of InsulFoam GF can reduce or eliminate the need for heavy earthmoving and compaction equipment. The InsulFoam GF blocks can be easily picked up and placed manually. At sites with rough terrains or poor access, InsulFoam GF blocks can be transported, handled, and placed faster than soil and other fills. Environmentally Safe. InsulFoam GF contains no ozone-depleting CFCs, HCFCs, or formaldehyde. It is an inert and highly stable product that will not decompose, decay, or produce undesirable gasses or leachates. InsulFoam GF is recyclable and saves for waste-to-energy (WTE) systems and landfills. Insect and Mold Resistant. InsulFoam GF can be manufactured with an inert additive that repels termites and carpenter ants. InsulFoam GF does not sustain mold and mildew growth. Proven Performer. For over 40 years engineers have been successfully using Geofoam worldwide. It’s currently approved for use by the Federal Highway Administration (FHWA), many state Departments of Transportation (DOT), and other government and private entities. Weather Resistant. InsulFoam GF can be transported, handled, and installed in most weather conditions and is unaffected by freeze-thaw cycling, moisture, and road salts. Other fill materials such as wood chips, sawdust, lightweight concrete, and soil can be weather-sensitive during installation. Maintenance Free. Under normal conditions, InsulFoam GF requires no maintenance for the life of the fill system. Homogenous Make-up. InsulFoam GF is manufactured with consistent properties throughout individual blocks. Other lightweight fill materials (such as used tires, wood chips, and fibers) can be varied and inconsistent in their make-up. Such inconsistencies can result in non-uniform load transfer and differential settlement. No Preloading. Unlike other fill materials, InsulFoam GF does not require surcharging, preloading, or staged construction.
Product Features
Job Specific Sizes. InsulFoam GF is manufactured to meet job-specific requirements. With varying maximum block sizes available from the Insulfoam facilities, it is important the designer contact the local Insulfoam Representative to determine maximum block sizes for each project. Adaptable. If job site block size adjustments are needed, InsulFoam GF can easily be cut on-site with hot wire tooling or saws. Clear Product Marketings. Each InsulFoam GF block is marked with the manufacture date, location, ASTM designation, and density.
