If you are building a dock or adding on to an existing dock, you can keep the dock afloat by adding flotations to it.
Flotations are typically foam filled with a polyethylene shell. You can usually get the floating drums for your dock in either white or black.
When you are ready to add floating drums to your dock, you do not need to hire a professional. In fact, you can do the work all on your own.
Here’s how to do it:
Purchase floating drums or dock floats, if you have not already done so, from a local boating or marine shop. You need to have around 30 pounds of flotation per square foot of your dock.
Attach the mounting hardware to your dock using a drill. Dock hardware is typically heavy duty steel designed for use with carriage bolts so that the dock can withstand the choppy water.
Slide the floating drums into place by lining up the mounting slots with the hardware for an air-tight fit on your dock. The flotations should encase the entire dock.
Now you have flotations on your boat dock.
