I'm going to be building a floating dock for our new cabin site on a lake. I'm going to be using blue plastic 55gal drums filled with foam as the floats. Any ideas on what type of foam and where to have it done or get it? I don't want to buy 5 cases of "stuff" spray foam and do it... any ideas?
I'm also open to any ideas any of you may have for lashing them together and attaching the planking to the drums. I plan on using pressure treated 2X6's unless someone has a better idea... plastic deck planking maybe?
