Articles are disclosed for use in providing both water-proofing protection to a foundation wall, and a support system for decorative landscaping material around the perimeter of a building. The article is in the form of an open pan having a waterproof and substantially impervious bottom, a continuous back-wall; a front-wall including perforations, and a pair of side-walls. The pan is used by placing it adjacent to a foundation wall at ground level with its back-wall abutting the foundation wall, its bottom on the ground at grade level, and its perforated front-wall spaced from the foundation wall. Additional pans may be placed adjacent to the pan at one or both of its side-walls. When so placed a plurality of pan articles of the present invention provide a continuous water impermeable carrier along a foundation wall which prevent water or other liquids from entering the ground immediately adjacent the foundation, while allowing such liquids to be drained from the pan at a controlled rate and at a distance from the foundation wall through the perforations in the front-wall. Additionally, the pan provides a barrier or mulch to prevent the growth of unwanted weeds or other plants around the foundation, while also providing stable boundaries for decorative material such as rock, bark or the like. In one preferred embodiment, opposed side-walls of the same pan are respectively a U-shaped groove, and a substantially upright tongue, thus allowing easy, but substantially waterproof groove and tongue joinder of adjacent pans.
