Abstract
Abstract A method of constructing an equipment pad and the resultant pad is disclosed. The method comprises the steps of providing a mold with fiberglass material laminated to the interior walls of the mold, providing a layer of polymer concrete in the base of the mold, covering the layer of concrete with a sheet of fiberglass material, covering the fiberglass material with an additional layer of polymer concrete, placing honeycomb material on the additional layer of concrete, filling selected cells of said honeycomb material with a polymer concrete, laminating a fiberglass sheet to the upper surface of the honeycomb material and sealing the upper sheet of fiberglass to the fiberglass laminated to the walls of the mold. The finished pad is then removed from the mold and inverted. If desired, an opening may be molded into the pad.
