The invention concerns a floor covering intended for industrial halls, especially large-area warehouses, which will withstand the load imposed by vehicles, machines and stored goods and provides a certain protection against the undesirable penetration of environmentally damaging fluids into the ground (5). It consists of several covering components (11) which can be welded together having an upper plate (1), a lower plate (2) and a gap (8) between them, the width of which is determined by a layer of expanded metal (3), for the connection of a leakage monitoring device (27). |
