Frost Cushion

Frost Cushion Description

Frost Cushion is manufactured from inert closed cell expanded polystyrene (EPS). It is used under concrete grade beams forming voids to compensate for frost and moisture-induced swelling of underlying soils that might otherwise lift or fracture the concrete structure. Frost Cushion will not collapse due to water absorption. It resists soil movement into the void space. Frost Cushion has excellent resistance to freeze/thaw and has low moisture absorption properties. It is not biodegradable and has no pest nutrient value.

Applications

Frost Cushion can be used under grade beams and other structural concrete members. It will support a total working load equivalent to the weight of 4 feet (1200 mm) of concrete. AMC is registered by the International Standards Organization (ISO) under the ISO 9001 Quality Assurance Program. This is a set of standards and criteria which is internationally recognized as an assurance of product quality and consistency.
