Abstract
A system and method for de-watering porous material, e.g., concrete. In select embodiments, durable, dimensionally stable anodes (DDAs), preferably configured as arrays on a strip, are impressed into the concrete and a pulsed signal is provided by a DC power supply to the DDAs and cathode rods inserted in soil. The DDAs comprise a valve metal substrate mesh having a semi-conductive coating of a precious metal, cement or ceramic. In select embodiments, conducting grout of a hydraulic cement-based mineral-aggregate may be used to emplace the DDAs. In select embodiments, a single cycle of the signal comprises a pulse train consisting of an initial positive pulse followed by a shorter duration negative pulse and ending with a short off period before re-cycling. The cycles continue until the porous material has been sufficiently treated.
