Geofoam for Seismic Protection

How Geofoam Enhances Seismic Resilience

In seismic zones, reducing lateral and dynamic forces on structures is critical. Traditional soil fill adds unnecessary weight that amplifies seismic load. EPS Geofoam offers a lightweight, engineered solution that helps mitigate seismic risk by reducing earth pressures and enhancing stability.

Lightweight Load Reduction

Because EPS Geofoam is 95–98% air, it drastically reduces the static and dynamic loads exerted on retaining structures and embankments during an earthquake.

Geofoam’s low density results in lower horizontal loads, helping engineers design walls and slopes that are more resistant to seismic failure.

Geofoam acts as a compressible buffer that can help absorb and distribute seismic energy—especially effective when used behind retaining walls or beneath pavements.

Geofoam is ideal for sites with weak or liquefiable soils, where heavy fill would otherwise amplify ground motion and compromise structural integrity.
