Elevation ® geofoam shall be cured a minimum of 72 hours at ambient temperature prior to use to allow blowing agent and condensate dissipation. Alternately, accelerated curing under heated area conditions shall be approved. 5. All Elevation ® geofoam blocks shall be shop-trimmed (molded edges removed) to assure face trueness and tight dimensional fit with adjacent blocks. 6. Elevation ® geofoam shall be specified using the material type designations listed in ASTM D6817 “Standard Specification for Rigid Cellular Polystyrene Geofoam. 7.
