  • Method of, and apparatus for drying damp basements
    Patent number: 4145270
    Abstract: In a method and apparatus for drying damp basements by electroosmosis, the inner surface of the basement walls are coated with a plaster or multi-layered coating of an electrically conductive non-metallic composition, which forms an electrode to which positive voltage is fed by a number of grounds arranged around the walls of the basement and embedded in the earth. These second electrodes are fed a negative voltage from the D.C. power supply, while their number is determined by a particular current density measured at the interface of the walls and the positive electrode and the building-directed face of the negative electrodes.
