Geo30 - Embankment Geofoam blocks (EPS)

Expanded polystyrene embankment FOAMCONCEPT GEO30

Blocks in various sizes made with EPS beads containing a flame retardant.

Cuts available by order

48’’ x 96’’ x 30’’
48’’ x 192’’ x 30’’

Compressive Strenght (10%)

(ASTM D1621) 210 kPa min. (30,3 lb/in2)


EPS beads should be considered flammable when subjected to a source of intense heat or a constant strong flame. They are vulnerable to petroleum-based solvents and prolonged exposure to ultraviolet radiation.

Ultraviolet Degradation

Prolonged exposure to ultraviolet rays will produce slight discoloration and crumbling of surface. Insulation properties will be reduced minimally unless exposure is long enough to reduce thickness. To avoid ultraviolet degradation, cover block as soon as possible.


  • Conforms to CAN/ULC-S701-01 standards
  • Conforms to CCDG 14301 standard (B1 MTQ insulation)
