Perform Guard® EPS Geofoam

 

Perform Guard® EPS Geofoam is used in ground fill applications where a lightweight fill material is required to reduce stresses on underlying soils. It has been used in applications worldwide for over 30 years. Perform Guard EPS Geofoam is a cellular plastic material that is strong but has a very low density - 1 % of traditional earth materials. It is produced in block form and is easily positioned at the work site. Perform Guard EPS Geofoam is unaffected by normally occurring weather at the time of installation and will retain its physical properties under engineered conditions of use.

Traditional earth materials are heavy and can cause settlement or instability of underlying soils. Other fill materials such as foamed concrete, waste tires, soil, wood chips, wood fiber, etc., have higher densities, are variable in their makeup and are not engineered due to field execution variables. They also have limitations in handling and can be weather sensitive, thus requiring staged construction and/or pre-loading, surcharging and draining, etc.
