a superior ultra-lightweight filling material used in building and road construction
Expanded Polystyrene (EPS) Geofoam is a geotechnical material, being used in construction activities in US, Japan and European Countries since 1970s. Its application in the construction and infrastructure industry is picking up in India.
EPS Geofoam is approximately 1% the weight of soil and less than 10% the weight of other lightweight fill alternatives, making it a superior, ultra-lightweight fill material that significantly reduces the stress on underlying and abutting subgrades.
The use of EPS Geofoam typically translates into benefits like lower construction costs and faster construction schedules because it is easy to handle during construction, often without the need for special equipment. In addition, EPS Geofoam can be easily cut and shaped on a project site, which further reduces onsite challenges.
Its service life is comparable to other construction materials and it will retain its physical properties under engineered conditions of use. EPS Geofoam is produced in blocks that can be cut into various shapes and sizes. As an engineered product, it can be produced to obtain the required compressive resistance.
Physical Properties of EPS Geofoam as per ASTM D6817
Note: The kg/sq.mt. figures have been converted based on kPa figures specified by ASTM D6817. Conversion Factor: 1 kPa = 101.97 kg/sq.mt.
