This assembly is supported by a structural concrete slab carrying insulation and waterproofing layers beneath a concrete topping slab. Stone boulders are embedded in a one-half-inch mortar setting bed with saw-cut bottom surfaces atop the topping slab. A three-inch perforated PVC pipe runs within a bed of one-to-two-inch river rock for drainage. Dimensions vary as specified per the plan.
