Briefly, it is the general name of all kinds of foam materials used in geotechnical engineering applications. A further definition is a material which is obtained by means of expansion, resulting in the formation of a variety of closed and internal gas-filled cells. Cell walls are solid but permeable to gases.

Geofoam is now worldwide accepted as as a geosynthetic product, such as geotextile, geomembrane etc.

Many geofoam materials are based on polymeric (plastic) or glassy foam. There are two types of polystyrene foam:

  • EPS (Expanded polystyrene)
  • XPS (Compressed polystyrene)

EPS geofoam blocks are factory-made construction materials that can be utilized in buildings, roads, and railways. However, among structural filler materials, it is the lightest. This EPS lightweight ground filling material technology has been developed to reduce the loads on the structures and the ground, as well as the ground settlement. Today, it can be observed that a variety of projects, including decreasing earthquake risks, vibration effects, filling gaps and strengthening retaining walls can be obtained by geofoam.

What is Geofoam?

Soils with low bearing capacity, high compressibility or liquefiable soils are “problematic” soils. Before constructing structures on these problematic soils, it is a must to make the necessary improvements in the ground in line with the necessary analyzes during the design phase. With soil improvement, it is aimed to increase the bearing capacity of the ground by reducing the voids in the ground by obtaining a safer ground where settlements are minimized. This soil improvement is done with geofoam. But this filling material offers different alternatives affecting the general perspective adopted by people. With the use of lightweight filling material, it is not aimed to increase the bearing capacity and strength of the ground, but to reduce the loads on the ground.

Geofoam Usage Areas


Many geofoam suppliers carry out EPS geofoam projects and applications in many areas such as transportation applications, housing projects, industrial structures, parks and gardens, landscaping applications, etc. Thus, they produce turnkey engineering solutions, including the supply of geofoam lightweight fill material from the preliminary project stage, its transportation to the site, stocking, and application. Other geofoam lightweight fill block application areas are given below;

  • Reducing excess fill weights on infrastructure lines,
  • Reducing settlements in highway embankments resting on weak and soft soils,
  • Light filling material applications in road and railway applications,
  • Road widening applications,
  • Increasing slope safety in areas with landslide risk,
  • Applications of reducing soil fill loads and miscellaneous loads on building floors,
  • Fast construction of bridge approach ramp embankments with light fill material,
  • Reducing the foundation depths in regions with high frost depth,
  • Forming the retaining wall backfills with a light filling system,
  • Creating artificial elevations and stages in various landscape applications,
  • Gap filling and raised floor applications,
  • Applications to prevent building foundation backfill settlements,
  • Load reduction and thermal insulation applications on green roofs.

Geofoam Production and Sales

EPS geofoam, a lightweight filling material, minimizes ground and building loads, as well as ground settlements. It is made up of blocks that come in a variety of forms, sizes, and strengths to suit the needs of the related project. Geofoam also offers new solutions for earthquake protection, shock, noise, and vibration dampening. It’s a product that’s available from a variety of manufacturers these days and it is possible to reach the best geofoam blocks application with leading companies.

Geofoam Prices

As a lightweight fill application material, geofoam is sold in volume over cubic meters. Geofoam prices vary according to the carrying capacity of the lightweight filling system material. For this reason, the technical teams of companies choose more economical materials with low density in applications that do not require high compressive strength. These situations are generally applications such as filling the gap, light vehicle transition.

However, some of the leading companies prefer high-density geofoam blocks with higher bearing capacity in highway applications, in road and railway foundation fillings where heavy loads affect the ground, heavy vehicle passages. As a result, material type and shipping costs determine geofoam prices.
