Abstract (en)
[origin: WO0042258A1] The invention relates to a drainage strip (10) for producing surface drainages. The drainage strip is provided with an inherently stiff plastic film that is profiled in such a way that open-end channels (22, 20) are alternately formed underneath the support plate and above the layer laying thereon. A liquid permeable and gas permeable covering strip (14) is adherently mounted on the upper side of the strip, which upper side faces the layer laying thereon. A number of through openings (24a, 24b) are provided in the strip-shaped sections (18) which laterally define the channels (22, 20). Said strip-shaped sections (18) are provided with profiles in the areas which are situated between the through openings (24a, 24b). The profiles increase the resistance against deforming when weight is put on.
