ABSTRACT:
A protective lining arrangement, which is intended for use in industrial halls, especially in large-area storage halls, and, on the one hand, is to be capable of being loaded to a high degree by vehicles, machines and stored goods while, on the other hand, is to provide excellent protection against undesirable seepage of hazardous liquid substances into the ground, consists of a plurality of protective lining components which are connected to one another by welded joints. Each of such protective lining components includes an upper plate, a lower plate, and a distancing layer of expanded metal which is interposed between the upper and lower plates and keeps them apart by a predetermined distance, while simultaneously providing between the two plates a gap space having a width corresponding to the predetermined distance. The gap spaces of the protective lining components can be evacuated and are connected via a measuring conduit to a leakage monitoring device.
