EPS Data Sheet

What Is EPS Geofoam?

EPS Geofoam is a lightweight, engineered fill material used when traditional soil or aggregate isn’t practical. It reduces load, speeds installation, and improves stability in challenging site conditions.

Road & Bridge Embankments

Lightweight support for highways and bridge approaches, reducing load and settlement in weak soils.

Foundation & Slab Insulation

Used beneath slabs and foundations to reduce structural load and improve energy efficiency.

Retaining Wall Backfill

Reduces lateral pressure and speeds installation in tight or unstable conditions.

Why Choose Geofoam Over Traditional Fill?

Geofoam blocks are engineered expanded polystyrene (EPS) products designed to provide high strength with minimal weight. Whether you need fill material for road embankments, retaining walls, building foundations, or custom landscaping designs, Geofoam blocks offer unmatched versatility and long‑lasting performance. Learn more in our FAQ below to see why Geofoam is becoming the go‑to choice for builders, engineers, and architects nationwide.

Geofoam blocks are lightweight, rigid expanded polystyrene (EPS) blocks designed for use in construction and landscaping projects. Despite their light weight, they provide excellent strength, stability, and durability for a wide range of applications.

Geofoam blocks are commonly used for road embankments, slope stabilization, retaining wall backfill, building foundations, landscaping, and even sports stadium seating. They are a cost-effective solution wherever lightweight, stable fill is needed.

Geofoam blocks are engineered to support heavy loads without significant settlement. Depending on the density selected, they can support roads, highways, airport runways, and large buildings while reducing stress on underlying soils.

Absolutely. Geofoam blocks can be cut and shaped on-site or pre-cut to match specific dimensions and designs. This makes them ideal for projects that require unique layouts or tight tolerances.

No. Geofoam is highly durable and will not decay, settle, or lose its integrity over time when properly installed. It is resistant to freeze-thaw cycles, mold, and pests.

Yes. While Geofoam itself is water-resistant, it is not a barrier to water. For projects requiring waterproofing, a protective liner or membrane may be added. The material’s closed-cell structure ensures it does not absorb significant moisture.
