The coating (1) comprises a matrix (11) of bituminous material in which a layer of conductor material (3) is embedded. The conductor material (3), which can be a metal net (13) obtained by knitting or weaving a conductor wire, or a thin perforated and stretched metal sheet, has portions that can be uncovered (13a, 13b, 13c) for being connected to corresponding portions of an adjacent coating (13a, 13b, 13c) or to another external conductor or to a voltage supply (53) or to ground (32,42). The coating can be used for waterproofing surfaces of buildings and shielding them from electromagnetic radiation, such as for example those generated by TV or cellular telephonic antennas, high voltage lines, etc. Furthermore, it can be used for other electrical and/or magnetic functions such as for shielding metallic structures, ducts, etc. from stray currents or for providing magnetic guides on industrial and road surfaces. <IMAGE> |
