A float module that can be combined with other float modules to form a floating dock apparatus with the float module being constructed with a flat concrete deck bonded with a construction grade adhesive to a closed-cell foam pontoon, the exposed surfaces of the pontoon being covered with a protective coating, particularly one having anti-fouling properties.

A peripherally weighted floating platform system comprising a peripheral frame with side portions and end portions and formed of a hollow plastic structure with a heavy material therewithin. There is a plurality of stringers which are parallel with each other and parallel with the side portions of the peripheral frame and secured to the end portions of the frame. A plurality of plank members are located parallel with each other and parallel with the end portions of the frame and secured to the stringers.

A floating dock system which comprises a plurality of locatable floats and interlockable deck sections overlying and supported by the floats. For interlock, the deck sections are arranged with interlapping ends for over or underlying next longitudinally adjacent sections with attachment receiving passages along such edges for positive connection therebetween. The deck sections are connectable to the floats to provide a dock of various, desired configurations. The float sections and the deck sections are hollow with the deck sections selectively fillable with expanded foam material. Selectively spaced and located connective passages are provided in the float and deck sections for combining the same into desired configurations and to meet various flotation requirements. Spanning and supporting members to extend between floats are available for particular installations. The variable positioning between deck sections and deck and float sections allows development of docks of various configurations including fingers or arms for slip areas and enlarged platform areas with the completed dock requiring only minimal, if any, water bottom connective devices.

A float which may be utilized individually or which may be joined to other such floats or used with other elements to provide flotation for a deck or dock unit. Though the particular shapes and attributes of the float may vary for the particular use, the basic float consists of a hollow, preferably rotocast, unit which combines an exterior skin with attachment accommodations having a selectable top surface and a first and second flotation concept. The first flotation is provided by the buoyancy of the hollow structure with the second achieved through a plurality of selectively shaped and positioned cavities extending upwardly from the bottom surface of the float to a location at or adjacent the upper surface of the float. With this dual flotation provision, should the exterior skin of the float be pierced, allowing water to fill the interior thereof, flotation is provided by air entrapment within the formed cavities. The float provides for selective upper surface arrangements dependent upon the desire of the user and may include a flat, or otherwise formed surface.

A floating dock assembly comprising a plurality of interconnected concrete float sections is disclosed. Each float section comprises a concrete shell having a deck portion, opposing side walls, opposing end walls, and an open bottom which together define a flotation container. A self-centering flotation core is disposed in the flotation container and has a bottom portion that extends outside thereof to increase the freeboard of the float section. The concrete shell further includes a pair of opposing, horizontally projecting concrete structural side flanges extending along the length of each side wall and a pair of opposing, horizontally projecting concrete end flanges extending along the length of each end wall. Each flange is of sufficient thickness to permit direct attachment of mooring accessories and dock hinges for interconnecting adjacent float sections without additional structural components such as conventional timber wales.
