Patent ID: 7763155

Claim:
A system for de-watering manmade structure adjacent natural structure at least part of which comprises bedrock, comprising: at least one channel bored in said natural structure, said at least one channel with a slope having a vertical component much greater than a horizontal component; at least one pipe in operable communication with a bottommost portion of at least one said channel, said at least one pipe installed with a slope having a horizontal component much greater than a vertical component, wherein said pipe facilitates draining fluid from said at least one channel; at least one first conducting screen comprising a grid of durable dimensionally stable anodes, said at least one first conducting screen in operable communication with said manmade structure; at least one first layer of cementitious material in operable communication with and at least covering said at least one first conducting screen; at least one second conducting screen comprising a cathode installed in operable communication with said natural structure, at least one second layer of cementitious material in operable communication with and at least covering said at least one second conducting screen; wherein at least part of said at least one second conducting screen is installed adjacent said at least one channel; and circuitry in operable communication with at least said at least one first conducting screen and said at least one second conducting screen, wherein said circuitry facilitates establishing a voltage differential between said at least one first conducting screen and said at least one second conducting screen; at least one moisture barrier in operable communication with and covering said second layer of cementitious material; and at least one third layer of cementitious material in operable communication with and at least covering said at least one moisture barrier.
