High density foam blocks by Geofoam International LLC provides the most reliable, highest level of stability for transportation or structural projects utilizing EPS Geofoam blocks. It is a clean, cost effective, lightweight material that can be used for many different applications.

  • EPS Geofoam can be factory cut to fit to size and accompanied with a detailed set of installation shop drawings showing the contractor how and where to place each block for easy installation.
  • Compressive resistance @ 1% deformation ranges from 2.2 psi to 18.6 psi.
  • EPS Geofoam blocks can be molded to virtually any size and provided at different densities depending on the requirement by the construction project.
  • EPS Geofoam is 100 times lighter than traditional fill materials like soil.
  • Maintenance following installation is not required.
  • The closed cell structure of the foam inhibits moisture absorption and the risk of mold or mildew growth.
  • Blocks can be pre-cut or field trimmed to be stacked easily in the field by the installing contractor.
  • EPS Geofoam can be provided with an EPA-approved termite and bug resistant material which meets the strictest certifications in the market.
  • Material can be delivered in a just in time method so no storage is involved.
