Geofoam in Tunnel Construction

A Lightweight, Load-Bearing Solution for Tunnel Construction

EPS Geofoam helps manage structural loads and reduce settlement in cut-and-cover and utility tunnel projects. Its low weight and high strength make it ideal for confined or sensitive underground environments.

EPS Geofoam is used in tunnel construction to control load distribution without overburdening underlying structures. Its consistent density and compressive strength help minimize soil movement, making it a reliable choice for backfill around tunnels, utility corridors, and underpasses. Because it weighs as little as 1 lb/ft³, it can be used in areas where heavy fill would otherwise pose a risk to structural integrity.

Easy to Handle, Quick to Install

Tight jobsite access and complex staging often slow tunnel projects—but not with EPS Geofoam. Lightweight and precut to spec, Geofoam blocks are easy to maneuver in confined spaces, speeding up installation while reducing labor and equipment needs. It integrates well with drainage and waterproofing systems, helping contractors stay on schedule without compromising long-term performance.
