Publication number: 20050217175Abstract: A portable, modular water garden structure, suitable for the containment of water and adapted to be readily assembled and disassembled, is provided. The structure first comprises a base unit, formed of a lightweight sturdy material, having an exposed outer surface, a top side, perimeter walls and an underside. The base unit is further characterized as having on its top side a generally centrally located depressed area suitable for use as a tub capable of accommodating an appropriate quantity of water. A moisture-proof flexible membrane is situated directly over the exposed outer surface area of the base unit, and extending over the tub and at least a portion of the upper edge of the perimeter walls. A layer of moisture- and flex-resistant material is formed over the moisture-proof membrane, covering the membrane and at least covering the exposed outside surfaces of the perimeter walls and any exposed outer surfaces of the base, so as to give a generally natural-looking appearance to said modular structure.Type: ApplicationFiled: April 2, 2004Publication date: October 6, 2005Inventors: Larry Leone, J.
