Standard Concrete Flotation System

Our management team has been designing and manufacturing this Standard Concrete Flotation System since the 1950s. Our High-strength Concrete Mix for this flotation system is 6,000 psi, far exceeding the industry standard.

Our Standard Concrete Flotation System are of a modular construction and possess the advantages of low cost, low maintenance, and extreme durability which assures a long life. They are designed and built to last for 40 years or longer.

Each concrete float module is solidly filled with polystyrene foam and surrounded by a concrete outer shell of special structural concrete, making it virtually unsinkable. After curing, these modules are then joined end-to-end with others to form floating boat moorage and other configurations. This joining of modules is either done with treated wooden walers and through rods or post tension cable and wooden bumpers at the float deck.

Standard Features:
  • Walkways from 5' to 12' wide and 10' to 12' long per module
  • Fingers 3' and 4' wide or wider, and 10' to 12' long per module
  • Standard construction is 16" freeboard
  • Greater or extra-low freeboard options are available on request

  • Standard Benefits:
  • Safe, strong and stable
  • Long lifetime and low maintenance mean better profit
  • Resistant to rot, corrosion and rusting
  • Never needs painting or protective coatings
  • Pollution free
  • This finger at Blaine Harbor is 40 feet long with no end pile.

    Utility Distribution:
  • Utility outlets can be installed in locker boxes or power pedestals
  • Planned routing can be done during the float casting process
  • Embedded PVC tubes in the float provide electrical chaseways for the float length with access to the sides by junction boxes
  • Trench covers are available in galvanized steel, concrete, aluminum or fiberglass
  • Utility outlets were installed in locker boxes at Blaine Harbor marina.

    Sub assembly can be done before the flotation system leaves our plant, which will save a considerable amount of on-site labor, on-site assembly time and equipment cost.

    Concrete floats can be secured in place with wood, concrete or steel pilings. Other sophisticated methods of holding the float in place can be engineered such as anchoring, spud anchors, or a jib attaching the float to the shore.
