摘要

1. Damp-proof courses, in particular bituminous damp-proof courses, which contain an impervious layer consisting of at least one plastic/metal composite foil, characterised in that they contain as the impervious layer a composite foil consisting of at least one metal foil of a thickness of 10 to 20 mu m and at least one plastic film, the composite foil having an elongation at break of 100-115% in the longitudinal direction and 30-35% in the transverse direction, measured according to DIN (German Industrial Standard) 53 455, and a tensile strength of at least 90 N/mm**2 in the longitudinal direction and 150-190 in the transverse direction measured according to DIN 53 455.
