PermaFloatŪ Float Drums offer durable flotation that can be easily applied to any new or existing dock system. This includes wood, steel and aluminum docks. PermaFloatŪ is rotationally molded, eliminating seams that could result in long term separation and leakage. The shell is.150 inches thick and manufactured of tough virgin polyethylene with imbedded ultraviolet inhibitors. This tough durable outer shell protects your dock system from the damaging effects of sun, saltwater and freshwater, debris, oil, gas, marine organisms and pollutants. Army Corp of Engineers approved PermaFloatŪ drums are filled with CFC/CHIC free expanded polystyrene, providing positive uniform flotation. Designed for ease of installation, the PermaFloatŪ extra wide side ribbing provides easy tool access to both mounting holes and slots and adds to the overall structural integrity. The PermaFloatŪ complete Dock Systems offer all but the lumber necessary for dock construction both for the professional and the beg
