A concrete floatation module adapted for use as a floating dock, breakwater, and the like. The module includes thickened portions of concrete extending lengthwise in a concrete shell preferably in the corner portions of the shell. The shell surrounds a buoyant foam core which may be used as a molding core for the floatation module. The thickened lengthwise extending portions of concrete include integrally molded tubular liners for creating passageways through the module for the passage therethrough of an interconnecting means, such as a steel cable. The tensioned steel cables maintain the modules in compression in an end-to-end relation thereby forming a single monolithic structure. Widthwise extending liners may also be provided to facilitate the interconnecting of laterally extending branches of modules. The floatation modules may be readily formed on-site by integrally molding the buoyant foam core and tubular liners in the concrete shell.
