Electro-osmosis is a modern execution of an ancient principle to cure rising damp. John Geraghty, an expert in this treatment, explains. 'Essentially, electro-osmosis creates a means of repelling moisture. We install a series of platinised titanium anodes into the affected masonry at one meter http://construction2.vacau.com intervals and introduce a very small, regulated and perfectly safe electrical charge into the wall just above ground level.' This 'constantly-on' system prevents water from rising, thus avoiding any recurrence of rising damp.
