The Flotation Modules are moulded in one piece from tough, high stress crack-resistant, thermoplastic polyethylene resin. The modules are self coloured with carbon black pigment for maximum 'ultra violet light resistance'. They are not effected by osmosis, marine organisms or chemicals normally present in the marine environment. In built mounting lugs allow direct connection of the modules to the frame work system. Floats can be filled with water or concrete to add ballast to increase stability. Ballast can also be used to raise and lower the float for different freeboard requirements. Floats can also be foam filled for extra security if required.
