    In my experience, they were either driven in by a drag line mounted pile driver or for smaller projects jetted in using water pressure. You sound like you're in a little over your head.

    just dump bags of dry cement in the water and hope it settles near the hole. :D

    sorry had to do it.

    How deep is the water? the need to be driven into the ground and it really needs to be engineered not just thrown in and hoping.

    What is the budget on the project? do you have conservation issues? Did you know what you were getting into?
