Abstract (en)
[origin: EP0269871A2] The floor covering according to the invention is intended for industrial warehouses, especially large-area storage depots, and is intended, on the one hand, to be capable of supporting high loads from vehicles, machines and stock and, on the other hand, to guarantee reliable protection against the undesirable escape of environmentally harmful fluids into the ground (5). It consists of a plurality of covering elements (11) which can be welded together and which have an upper board (1), a lower board (2) and a gap (8) arranged between these two boards and of a width defined by a layer of expanded metal (3). The gaps (8) can be evacuated and are connected via a measuring line (16) to a leakage monitoring unit (17). <IMAGE>
