A method for dehydrating a porous material using electro-osmosis, includes applying a pattern of D.C. voltage pulses to an anode system embedded in the porous material, wherein the anode system is electrically interactive with a cathode structure embedded in earth, and wherein the pattern of D.C. voltage pulses, has a pulse period T in a range from about 3 to about 60 seconds, and each pulse period T includes a positive pulse duration of T+ from about 0.7T to about 0.97 T, a negative pulse duration of T- from about 0.01T to about 0.05T, and a neutral pulse duration of Tp from about 0.02T to about 0.25T. In another embodiment, each pulse period includes two or more positive pulses separated by at least one of either a negative pulse or a neutral pulse, with the positive pulse duration being the combined duration of the two positive pulses.
