Soil Moisture Control Using Intelligent Single-Well Electro-Osmotic Dewatering Systems

New designs for using single (Electro-Osmotic Pulse) EOP-driven dewatering wells and interactive arrays of EOP-driven wells can provide new capabilities for maintaining low-soil moisture conditions under and around structures.  The new approaches using single well vertical electrode arrays for structures that do allow ready access to the inside of the foundation and arrays of wells both outside and inside the space under a building when access to the space is available.  Cathodes connected to variable resistors are used to reduce the opportunity for corrosion of buried metal objects in the vicinity of the EOP system.  A pre-selected pulse train of DC voltage pulses is employed to migrate water from under the crawl space and maintain dry conditions that reduce the opportunities for corrosion of exposed or buried utilities.
