OK so I'm finally undertaking my permanent dock project, after procrastinating for 3 years now. My old floating dock is in dire need of repair and after 10 years I've decided to just retire it and start over.

I'm building this in the water so I have some of the standard issues with support installation...I have an idea.

I have a plethora of 8" heavy duty PVC conduit sections, 20' long. I was thinking that I'd drive these into the pond bottom at appropriate distances, pump the water out of the pipe, use a pressure washer with an extension to blast the mud out of the bottom, then set some rebar in and pour concrete in the pipe. Voila, solid, permanent pillars for my dock. The pipe stays obviously.

Yes I know getting the concrete in the pipe is gonna be a challenge....but where I'm building the dock off of my levee I have power, and I was going to use a cement mixer and split one of the conduits in half for a funnel of sorts to the pillars.

Sounds like a ton of work right? I was going to test out the process on shore - I need 4 pillars on the bank before I get to the water's edge. If it just sucks too bad to accomplish when I'm on terra-firma then I'll scratch the idea and just go with 4" galvanized pipe driven into the pond bottom.

What do y'all think?
