Abstract
Abstract A marine float for use in conjunction with a concrete floating dock system and methods for manufacturing the same. The float consisting of a buoyant core of expanded polystyrene foam supporting a textured deck of standard aggregate concrete and surrounded by a shell of fiberglass reinforced cement. The float is fabricated as a unitary whole by pouring a layer of standard aggregate concrete in a form over a texturing mat to provide the textured deck, placing a buoyant element over the poured deck and spraying a layer of fiberglass reinforced cement around the buoyant element before any of the concrete elements has set. All concrete elements are then permitted to set to form a monolithic float.
