Permafloat^® Lift Tanks

Cellofoam augments its standard Permalift™ Marine Lift Tanks with a product line of lift tanks made using our Permafloat^® dock float molds.

Permafloat^® Lift Tanks are commonly used in boat lifts but can also be used to gain freeboard on existing docks, temporarily lift dock sections for repairs or to replace the flotation, or to eliminate twisting and listing to stabilize the dock. These heavy wall tanks are filled with water and submerged and then re-floated by evacuating the water with air pressure.

Permafloat^® Lift Tanks are custom made to order with customer-specified hole placements. They are available in nominal wall thicknesses of .350” and .375” and meet Association of Rotational Molders (ARM) industry standards.

Purchasers of our floats and lift tanks should engage with professional design experts to incorporate these products into their marine systems.
