Abstract
An Electro-Osmotic Pulse (EOP) system is used to dewater structure, both natural and manmade. Preferably, the system employs durable, dimensionally stable anodes affixed to structure in a configuration designed to maximize electrical contact with the structure and minimize electrode gas generation. The anodes and cathodes are attached to a DC power supply that provides a voltage potential between them. DC power is cycled until the structure has been sufficiently treated. Select embodiments employ perforated metal pipes as cathodes for the purpose of transport and drainage of fluids. In select embodiments of the present invention, the cathodes are connected to variable resistors designed to reduce opportunity for corrosion of buried metal objects in the vicinity of the EOP system. Select embodiments employ a pre-specified pulse train of DC voltage pulses to migrate water from under a crawl space while moving available cations in the soil. Select embodiments also protect large structures such as concrete dams.
