    Sledgehammers (or similar) and lots and lots of manpower I’d guess. It’s how they made it watertight before they drained it I’m interested in

      The weight of the water will push wooden pilings together. The flow of water though the gaps will also bring mud and debris into the cracks.

      It’s not perfect, and would need a lot of pumping/water removal, but it’s just a case of manpower, at that point.
