Abstract (en)
[origin: EP0111306A2] 1. Method for drying and protection of masonry from recurring dampness, in which the drying process is carried out by means of an electromotive apparatus and the seal is formed by means of a hydrophobic medium introduced into holes bored at an angle to the ground surface, characterized in that the upper row of electrodes is set into the masonry spaced from the negative electrodes by up 1 metre, and preferably in the neighbourhood of the earth surface, and in order to achieve even drying the spacing between the positive electrodes in a row is determined depending on the size of the dampened area and the electrodes are divided into groups which are supplied from separate sources, in that the holes for the hydrophobic medium are bored outside the zone of influence of the electrical field above the upper row of electrodes, and in that the hydrophobic medium is continuously introduced into these holes during the flow of current which, following the principal of continuity of current as well as capilliary and gravitational transport and convenyance, penetrates into the capilliaries and pores where it spreads out, where the electrokinetically downwardly-transported water is removed, so that a seal against dampness is formed.
