What is Geofoam?

Geofoam, or Expanded Polystyrene Fill, is a high-performance rigid insulation consisting of a closed-cell, strong, but lightweight premium quality expanded polystyrene (EPS) foam.  Geofoam, a lightweight fill and soil substitute is often used for structural application to reduce the load in countless residential, commercial, and industrial applications.  Our product is approximately 100 times lighter than most soil and at least 20 to 30 times lighter than other lightweight fill alternatives. This extreme difference in unit weight compared to other materials makes Geofoam such an attractive material. The lighter load can reduce settlements and can improve stability against bearing and slope failures.

Some of  the most common uses for Poly-Foam (Geofoam) include:

  • Road construction
  • Slope Stabilization
  • Retaining wall backfill
  • Road widening
  • Stadium and Theater Seating
  • Landscaping
  • Bridge Abutments
  • Levees
  • Loading Docks
  • Bridge Under fill
  • Airport Runway
  • Compensating Foundation
  • Culverts & Pipelines
  • Ramps
  • Parking Structures
  • Rail Embankment
