Floating Dock Materials

Dock Materials

In the manufacture of floating docks, several dock materials can be used.

Dock Floatation

  • Our Wahoo line of floating docks utilizes PERMAFLOATĀ® Dock Flotation Drums.
  • The Permafloat Float Drum is a one-piece rotationally molded float drum that eliminates seams that could result in separation and leakage. The .150″ thick shell is made of tough virgin polyethylene with ultraviolet inhibitors. This tough shell prevents damage from the sun, saltwater, fresh water, debris, oil, gas and marine organisms.
  • PERMAFLOAT Float Drums are foam filled with expanded polystyrene, that Does Not Contain CFC’s or HCFC’s.
  • PERMAFLOAT Float Drums have a flat top with molded-in mounting holes for easy attachment to any dock framework; whether it be wood, steel, or aluminum.
  • PERMAFLOAT Float Drums, used in the construction of floating docks, will provide long lasting and carefree encapsulated flotation, which will result in long range savings for commercial, municipal, public and recreational docks. They can be simple construction units, or large and complex marinas.
  • If you have a floating dock, or are considering building a floating dock, on a waterway that mandates encapsulated flotation, PERMAFLOAT Float Drums are the answer for you, because PERMAFLOAT meets all known current requirements for encapsulated flotation.

  • Aluminum is truly the ideal structural material for dock systems. In short, aluminum demonstrates excellent weathering characteristics as a result of its rust prohibiting properties and exceptional structural strength. This combination of properties virtually eliminates maintenance and greatly increases the dock’s longevity. Moreover, when used for decking, our in-house designed aluminum floor is cool to the touch, splinter free, seamless and water-proof. Our docks will never need sanding, sealing, staining or painting.

    Our only maintenance recommendation is periodic cleaning with a water hose to prevent dirt build-up. Spend time enjoying your dock rather than the hours of maintenance required for wood and steel docks.

    Because steel is ~3 times more stiff than aluminum, aluminum docks must be designed and manufactured significantly different than traditional steel docks to include substantial wall thickness, gusseting and bracing.
