<p>A method for the concealed laying of ducting for electrical wiring systems in buildings involves the laying, directly onto a wall (1) to be plastered, of a ducting (4) having a thickness or relief less than the layer of rendering or plaster (3) intended to cover said wall, so as to be able to be contained in said layer. The method can also be applied to ready plastered walls of buildings, with the additional step of preliminary removal of the rendering (3) over a width sufficient to introduce a ducting (4). The ducting (4) is of the flexible type, consisting of at least one tubular element (5) for containing one or more cables (6), and has a relief, relative to the wall (1) on which it is mounted, of less than 10 mm. At least one tubular element (5) is already provided internally with one or more cables (6) at the time of laying so as to allow simultaneous laying of ducting (4) and cables (6).</p> |
