Lift Tanks
Lift tanks are how you get a floating dock section out of the water without a crane. You attach the tanks below the section, pump them out, and the added buoyancy raises the dock enough to inspect the underside, replace floats, repair framing, or float the section to a new location.
Dock Builders Supply stocks lift tanks from Eagle, DPI, and Permafloat in a range of capacities. They are a standard tool for marinas doing their own maintenance and a smart rental-alternative purchase for contractors.
See all dock flotation options. Tell us the weight and dimensions of the section you need to lift and we will size the tanks for you.
