Foam-Control® Geofoam is a geotechnical product used in fill applications where a lightweight material is required to reduce stresses on underlying soils or lateral pressures to retaining walls, abutments or foundations. 

Overview of Geofoam

Geofoam has been used in engineering and geotechnical applications, specifically Geofoam transportation applications, worldwide for more than 30 years. Foam-Control® Geofoam is a cellular plastic material that is strong, but has a very low weight - 1 percent of traditional earth fill materials. Geofoam is produced in block form and is easily positioned at the work site. Foam-Control® Geofoam is unaffected by normally occurring weather at the time of installation and will retain its physical properties under engineered conditions of use.

Benefits of Geofoam

  • Predictable material behavior
  • Manufactured to meet ASTM D6817
  • Variety of Types to meet specific project requirements
  • Super lightweight compared to other fills
  • Inert in long-term burial conditions, no leachates

Geofoam can quite literally be the essential building blocks for construction projects requiring embankment fill.  Often available in 1 x 1.2 x 2.4 to 5-m (3 x 4 x 8 to 16-ft) blocks, the material can be used to reduce loads on underlying soils, or to build highways quickly without staged construction.  It has been employed to repair slope failures, lower lateral loads behind retaining structures, reduce vertical pressure on below-grade structures, accelerate construction and minimize differential settlement at bridge abutments. Read More.
