EPS Geofoam Applications: Retaining and Buried Wall Backfill

Expanded Polystyrene (EPS) Geofoam has many building and construction applications. Some of the common uses include road projects, bridge construction, and rail embankment build-up. Another common use for EPS Geofoam is backfilling behind retaining walls and buried structures. Using it as backfill in these structures greatly reduces lateral pressures because it is so lightweight. However, although it is lightweight, the compressive resistance is naturally high. 

Cost-Effective Retaining Wall Backfill

Horizontal pressure acting on a retaining wall is directly proportional to the weight of the backfill being used. While traditional, heavier backfill options require a more robust structure to compensate, structures using EPS Geofoam in the backfill soil do not require such a robust retaining wall. This naturally reduces the time and cost of a project.

Safer Retaining Wall Backfill Alternative 

At the same time, the use of EPS Geofoam backfills behind retaining and buried structures also limits the horizontal forces that might develop during catastrophes such as earthquakes. This makes it an ideal choice of fill material for these sorts of environments. That means it’s not only cost-effective, it’s also safer, too.

No matter the type of construction application it is used in, EPS Geofoam saves a tremendous amount on cost, time, and labor when used in lieu of other traditional offerings.
