EXPOL GeoFoam (EPS – Expanded Polystyrene) is a lightweight expanded polystyrene fill that eliminates lateral pressure and vertical movement. It is an ideal solution for sites with challenging ground conditions.

A multi-functional foam product, EXPOL GeoFoam (EPS – Expanded Polystyrene) is suitable for a wide range of applications, including construction on soft ground, slope stablisation and civil infrastructure work such as bridge abutments, airfield pavements and railway track systems.

EXPOL GeoFoam (EPS – Expanded Polystyrene) is preferred by specifiers and engineers because it reduces construction costs and timeframes, is easy to handle, can be cut on site, and is unaffected by weather conditions.

EXPOL GeoFoam (EPS – Expanded Polystyrene) is supplied in a range of densities and sizes to suit the engineering design.

Choosing the correct density of EXPOL GeoFoam (EPS – Expanded Polystyrene)  will depend on the compressive loads applied during its service life. All blocks can be cut to suit different project specifications, including angles and two dimensional profiles.
