Abstract
An anti-vegetation system for retarding growth around a structure extending from the ground includes a plurality of mats. A first mat includes at least one predefined scoring pattern to accommodate the shape of the structure extending from the ground. A plurality of scoring patterns can be included to accommodate a variety of shapes and sizes. When a scoring pattern it utilized, and the corresponding portion optionally removed, the mat can be positioned on the ground and partially around the structure extending from the surface. A second mat is positioned adjacent to the first mat and effectively surrounds the structure extending from the ground. Additional mats can be placed adjacent to the first and the second mat to increase the size of the protected area. Adjacent edges can utilize corresponding outwardly extending lips to improve the sealing efficiency of the edge-to-edge regions.
