Industrial floors. General term for floors with a wide variety of industrial uses, e.g. in-plant transportation routes, storage areas, floors in workshops, industrial premises, laboratories and the like. In the broadest sense industrial floors include all floors which are not used for living purposes or as outdoor roads.
In addition to adequate bearing strength, abrasion resistance and the best possible characteristics with regard to cleaning and maintenance, certain special properties are demanded of industrial floors, depending on the type of service, e.g. an extremely level and flat surface in computer-controlled high-racking warehouses, resistance to various chemicals and solvents in production halls, laboratories or tank farms, electrical conductivity in areas with a potentially explosive atmosphere or freedom from pores in clean rooms, e.g. in the pharmaceutical and electronics industries.
Industrial floors are mostly complex multi-layer structures, e.g. consisting of subgrade, sub-base, moisture barrier layer, load-bearing concrete with expansion joints and settlement joints, overlay and special wearing courses.
The latter may consist, for example, of bituminous coverings, fibrous or polymer concrete, epoxy resin-based reaction polymers, polyesters, polymethyl methacrylates or polyurethanes, plastic (e.g. PVC) or elastomers (e.g. synthetic rubber) as tiles or from the roll or ceramic coverings.
For various components of industrial floors there currently exist standards set in other contexts for composition, characteristics and testing, e.g. DIN 1045 (July 1988), amongst other standards, for concrete, DIN 18 560 T 1-5 (Aug. 1981 - Apr. 1985) for overlays, DIN 1995 T 1-5 (Oct. 1989) for bitumen and the A 80 worksheet issued by the German Working Group for Industrial Construction "Industrial Floors made from Reaction Polymers".
