About this detail

A cast-in-place concrete structural slab supports a layered waterproofing and insulation assembly, topped with a sloped cast-in-place concrete topping slab. A three-inch PVC perforated pipe collects subsurface drainage within a bed of one to two-inch river rock beneath the sculpture and surrounding stone boulders. A recessed light fixture integrates into the cast-in-place concrete paving at the edge of the assembly. The sculpture is installed by others and anchored through the drainage layer.
