Expanded polystyrene lightweight fill is used as backfill material underneath road infrastructures, bridge abutments, bridges and overpass access roads. Install the SR.EPS^TM lightweight fill blocks when soil conditions are unstable or sloped to limit settlement, shifting, sliding or compressing underlying ground or when a higher compressive strength for existing conditions is necessary.

Prevents uneven frost heave from causing cracking and premature deterioration on pavement or concrete exposed surface. Reduces the weight placed on underground structures such as roads, rail and subway underpasses, as well as culverts, ducts and pipelines.

Indicated for applications requiring a lightweight and durable filler material such as site filling around constructions and for landscape projects with considerable level variations.

Blocs are available in a wide variety of compressive strengths varying from 40 kPa to 276 kPa [5.8 PSI to 40 PSI].
