Abstract
Electro-osmosis, in the form of Electro-osmotic Pulses (EOP) can be used as a means to prevent water intrusion in below grade spaces. This technique has been evaluated in a test basement, and at implemented at several field locations. The testing within the scope of this work looked at the effectiveness of EOP with two different backfills, and in conjunction with conventional repair techniques. EOP was found to control moisture in a concrete wall effectively with both a clay and a gravel backfill, with the clay performing slightly better than the gravel. When the EOP configuration was changed from four cathodes surrounding the test basement to two cathodes, no significant change in EOP effectiveness was observed.
