Pond Boss Forums GENERAL QUESTIONS Property Projects & Construction Another Dock Question

I've never used wood posts in a BOW. I can't imagine what equipment it'd take to drive a 4x4 into the ground deep enought to be stable.

I think Menards has screw points that will bolt into 2" galv. pipe and you can just screw them into the pond bottom with a large pipe wrench. Use a "U" shaped bracket with ears on it and clamp the pier joists to the pipe. Or, they make pier fittings that will clamp a horizontal pipe to the vertical ones, and you lay the joists on top of the horizontal pipe.
