Geofoam – Structural EPS Insulation

The Leader in Engineered Light Weight Fill Material

InsulFoam® GF (EPS Geofoam) is a lightweight, geo-synthetic foam fill material used  as an alternative to various fill-materials, as a soil stabilizer, and in various engineered applications.

Geofoam Advantages:

  • Superior stability
  • Long-term R-value
  • Lighter than most fill materials
  • Cost-effective
  • Meets or exceeds the requirements of ASTM D6817
  • Does not typically require surcharging, preloading, and staging
  • Environmentally friendly, 100% recyclable
  • Contains no HCFCs or formaldehyde
  • Resists insects, mold, decomposition and severe weather conditions (freeze-thaw cycles, moisture)

Design Considerations

  • For InsulFoam GF applications, design should not exceed 1% strain for combined live loads
  • In conditions where InsulFoam GF is periodically subjected to submergence from fluctuating ground water, add 1.87 lb/ft3 (30 kg/m3) to the InsulFoam GF design density.
  • In conditions where InsulFoam GF is continually below ground water, add 5.00 lb/ft3 (80 kg/m3) to the InsulFoam GF design density.
  • In earth work applications such as le- vees, dikes, and berms, uplift buoyancy forces must be considered. The buoy- ancy force must be counteracted with overburden or restraint devices with geogrids or geomembranes.
