EPS is not soluble in water.
EPS is resistant, at ambient temperature, to:
- alkalis
- dilute inorganic acids
- gypsum plaster
- most alcohols
- portland cement
- silicone oil
- solvent-free bitumen
EPS can be damaged by, and shouldnot come in contact with the materials below. Protect EPS geofoam from contact with these materials both
during construction and after project completion using an appropriate hydrocarbon-resistant geomembrane or other physical barrier:
- hydrocarbons
- chlorinated hydrocarbons
- organic solvents
- ketones
- ethers
- esters
- diesel and gasoline
- concentrated acids
- vegetable oils
- animal fats and oils
- paraffin
If using EPS geofoam in a location ofcontaminated soils, laboratory testing should be performed to determine the nature of the contaminants, e.g.
methane, and their possible impact on the EPS geofoam.
