Custom Dock Floats
Dock floats are what keep your dock afloat. There are many companies that sell floats specifically designed for docks. Some floats are made of polyethylene plastic and may or may not be foam filled. Other floats are made of plastic coated Styrofoam.

The main function of the foam filling to make the float stronger, otherwise the shape of the float would cause the plastic to collapse on itself. The foam will absorb water over time so if the plastic shell is punctured, the dock should be repaired immediately as there is no way to dry the foam out once it is wet. This particular float costs about $260 not including shipping, weighs 110 lbs, and displaces 1815 lbs of water. dock builder in Bergheim, TX. dock builder in Bergheim, TX.

Standard 55 Gallon Plastic Drums
Standard 55 gallon polyethylene drums have been used as dock and houseboat floats for at least 20 years and have proven to be extremely reliable. 55 gallon plastic drums cost about $40-60 new and are used in huge quantities in the food industry. When used for food storage, the FDA typically does not allow the drums to be re-used. This is great for the dock builder in Bergheim, TX because reconditioned drums in excellent condition are available in most communities for $5-20 and with little shipping expense.
Because of their round shape, 55 gallon drums are extremely strong and do not need to be foam filled. This makes them significantly lighter than foam filled floats. And if they are ever damaged, the water can be completely drained and the drum can be repaired "as good as new" without the concern the inside foam has become waterlogged.
A typical 55 gallon drum weighs about 22 lbs and displaces about 480lbs of water. A 20 x 8 foot dock would float on 12 of these drums. Even at $20 each, the total cost of flotation would only be $240 as opposed to $900 for custom dock floats we discussed earlier.
There is at least one company that has started manufacturing aluminum dock kits that are designed to use standard 55 gallon polyethylene drums for flotation. These kits completely enclose the drums in an aluminum truss structure and are designed to work with any common decking material. The truss structure is so strong that poly dock wheels or even a highway rated axle can be added to the finished dock to make it easy to move in and out of the water. In addition, these docks can be registered and insured as U.S. Coast Guard approved boats. In some areas this can be advantageous if dock permits are difficult to acquire.
