Geofoam – Slope Stabilization

Slope Stabilization, Retaining Walls, and Buried Wall Backfill

If you’re working on supporting slopes, retaining walls, or backfilling tricky terrain, EPS Geofoam is a lightweight but powerful solution that can help. Designed to reduce pressure on underlying structures and simplify even the most complex earthwork challenges, EPS geofoam can help create stronger, safer projects from the ground up.

How Is Geofoam Used in Slope Stabilization and Retaining Wall Projects?

So, whether you’re working in hilly terrain, reinforcing a hillside, or constructing a large retaining wall, EPS geofoam is used in a few key ways:

• Slope Stabilization & Erosion Control
• Retaining Wall Backfill
• Buried Wall Applications
• Bridge Abutment Fill
• Void Fill in Unstable Soil Conditions

EPS blocks are especially useful when there are poor soil conditions where traditional fill would be too heavy or unstable. The foam is engineered to reduce lateral forces on retaining structures, lowering the risk of shifting, sliding, or collapsing over time.

Why Choose Geofoam for Slope Stability and Retaining Walls?

• Extremely Lightweight: At just a fraction of the weight of soil or aggregate fill, geofoam minimizes pressure behind walls and on slopes.
• Fast Installation: No need for compaction or curing because EPS blocks can be placed quickly.
• Predictable Load Performance: Consistent and stable—geofoam resists settlement and won’t change shape over time.
• Improved Safety: EPS geofoam reduces the risk of landslides and wall failure by minimizing lateral stress.
• Weather-Resistant: It won’t break down from moisture, rot, or pests. This is even true in tough climates.

Frequently Asked Questions about Geofoam for Slope Stabilization

Can geofoam be used behind both gravity and cantilever retaining walls?

Yes! EPS geofoam can be used with a variety of retaining wall designs. The foam’s low density reduces the earth pressure exerted on the wall. This allows for slimmer or more cost-effective wall systems while maintaining strength and reliability.

How does geofoam help prevent erosion on steep slopes?

By reducing the weight load on top of a slope and filling voids in unstable areas, EPS geofoam helps stabilize the ground and prevent runoff from displacing soil. It’s an especially smart choice for regions prone to landslides or heavy rainfall.

Is geofoam a long-term solution for buried applications?

Yes. Geofoam is moisture-resistant and doesn’t degrade over time. This makes it ideal for long-term buried use. When installed with proper protective layers, it performs reliably for decades without shifting or settling.
