ABSTRACT:
Secondary leak containment for petroleum dispensing stations utilizes a rigid container mounted in the foundation beneath the station. The container has an outwardly directed flange positioned at the midplane of the upper concrete slab. A removable cover and panel are used to prevent concrete from entering the container when the concrete slab is poured and formed. The container rests upon a first depth of compacted soil used to cover the petroleum supply tanks and is surrounded and supported laterally by a second depth of soil and or gravel that extends upwardly to support the concrete slab.
