Terrafoam EPE
Rebounding Polyethylene Void Fill for Specialized Geotechnical Applications
Terrafoam EPE is a closed-cell polyethylene compressible fill that absorbs strain from frost heave and swelling soils while maintaining its shape through elastic recovery.
- Non-Collapsing Void Fill
- Elastic Compression & Recovery
- Suitable Select for Hydrocarbon Exposures
- Low Water Absorption
What is Terrafoam EPE?
Terrafoam EPE is a foamed polyethylene void form designed to protect structural concrete elements such as grade beams, structural slabs, and pile caps from subgrade movement. Unlike crushable void forms, Terrafoam EPE compresses elastically and rebounds after loading, helping prevent water accumulation and ice formation beneath concrete elements. The material is manufactured from low-density closed-cell extruded polyethylene, providing excellent freeze/thaw durability, low water absorption, and long-term buoyancy characteristics.
Terrafoam EPE Applications
- Grade Beams
- Structural Slabs
- Pile Caps
- Select hydrocarbon exposure conditions
- Cold-climate geotechnical applications
