The invention relates to a support sheet (10) for ground or wall coverings which are exposed to the weather. The inventive support sheet comprises stiff plastic sheeting (12) with a pattern of cup-like projections (14; 16) projecting out of the sheeting plane at a distance from one another. The ground or cover walls (18; 20) have an essentially level surface and run parallel to the sheeting plane. The cup-like projections (14; 16) project alternately from opposite sides of the plastic sheeting (12). According to a preferred configuration, a highly resistant lattice fabric (22) which is permeable to gaseous, vaporous, liquid and paste-like media is provided on the outside of the cover walls of the projections (14) which project from the sheeting plane on the covering side. |
