Abstract
Below grade fluid containment structures, which may include a foam floor and a foam wall extending upward from the floor, the foam wall being formed from foam panels. A granular material is provided for reducing hydraulic soil pressure against an exterior face of the foam wall that would otherwise be exerted by the soil, if the soil were allowed to be positioned up against the foam, particularly the foam wall. The well-draining granular material may be gravel, crushed stone, or the like, which provides better drainage as compared to the surrounding soil material. The interior face of the foam is coated with an elastomeric abrasion resistant impact resistant polymeric coating that seals the below grade interior space defined between the floor and the wall in a seamless water-tight configuration.

A below grade fluid containment structure comprising:
- a foam floor;
- a foam wall extending upward from the floor, the foam wall being formed from foam panels;
- a granular material for reducing hydraulic soil pressure against an exterior face of the foam wall, the granular material being positioned to the exterior surface of the foam wall, between the foam wall and soil, an upper surface of which soil defines the grade;
- wherein an interior face of the foam wall is coated with an elastomeric, abrasion resistant, and impact resistant polymeric coating that seals a below grade interior space defined between the floor and the wall in a seamless, water-tight configuration.
