Deep Dive Systems imports a wide range of Poralu Marine floats. They are manufactured by centrifugal casting, and the moulded forms are filled with expanded polystyrene. All floats are waterproof, with identical strength and uniform fastening systems. The special Poralu Marine foaming technique makes them unsinkable and resistant to frost and impact.

Besides being resistant to hydrocarbons and other pollutants common for ports, these floats do not pollute in any way the surrounding aquatic environment.
