I wondered about their plans for "the big dig" - lining the walls of a large excavation with concrete to prevent the intrusion of water?..but the water percolates up from the bottom of the hole - as seen in the several cans they have sunk. Putting in a "floor" would keep out the water - and prevent digging.
The water percolates equally from the bottom and the sides. There being more area on the sides, it would be much more advantages to line the sides of the excavation!
