Geofoam
Ultra-Lightweight EPS Fill for Geotechnical Applications
Geofoam is a rigid closed-cell EPS lightweight fill used to reduce settlement, improve stability, and lower loads on underlying soils and structures.
- Ultra-Lightweight Fill
- Reduces Settlement
- Improves Stability
- Easy to Handle On Site
What is Geofoam?
Geofoam is a rigid expanded polystyrene (EPS) lightweight fill used in geotechnical construction to reduce loads on soils and structures. Because it weighs approximately 1% as much as soil, Geofoam helps control settlement, improve stability, and reduce lateral pressure in areas where conventional fill would be too heavy.
Geofoam blocks are easy to handle, cut, and shape on site, allowing engineers to solve difficult ground conditions while accelerating construction schedules.

Geofoam Technical Data
Geofoam blocks are available in custom sizes and
fabricated shapes to meet project requirements. Typical
standard block size is approximately 50″ × 49″ × 98″ (1.27 m
× 1.24 m × 2.49 m), with lengths available up to 220″ (5.59
m). Custom fabrication is available.
Geofoam Layout & Project Design Support
For large or complex projects, Beaver can support project-specific Geofoam layouts, block planning, and custom fabrication requirements. This helps contractors visualize the install, coordinate block placement, and reduce field cutting on site.

G-Tec
G-TEC is an elasticized EPS board for geotechnical applications where controlled compressibility is needed between soil and structural elements. It helps absorb soil movement, reduce lateral earth pressures, and improve protection against freeze-thaw and seismic loading.
