Claim 13:
14. A weed barrier mat, comprising:
an upper mat having a first upper tire section and a second upper tire section, each of the first upper tire section and second upper tire section having a pair of opposed side widths perpendicular to a pair of opposed side lengths, the first upper tire section and second upper tire section arranged such that one of the pair of opposed side lengths of the first upper tire section and one of the pair of opposed side lengths of the second upper tire section are in parallel relationship and adjacent to one another with less than about a quarter inch gap between the adjacent opposed side lengths;
an upper mat joint created by the adjacent relationship of the first upper tire section and second upper tire section;
a lower mat having a first lower tire section and a second lower tire section, each of the first lower tire section and second lower tire section having a pair of opposed lower side widths perpendicular to a pair of opposed lower side lengths, the first lower tire section and second lower tire section arranged such that one of the pair of opposed lower side lengths of the first lower tire section and one of the pair of opposed lower side lengths of the second lower tire section are in parallel relationship and adjacent to one another with less than about a quarter inch gap between the adjacent opposed lower side lengths;
a lower mat joint created by the adjacent first lower tire section and second lower tire section, the joint located at a center position of the lower mat; and
a corrosion-resistant fastener attaching the upper mat to the lower mat;
wherein the upper and lower mats are arranged such that the first upper tire section is centered over the lower mat joint with the side lengths of the first upper tire section parallel to the lower side lengths of the lower tire sections;
wherein the second upper tire section is attached to either the first lower tire section or to the second lower tire section but not to both;
wherein an unattached portion of the second upper tire section forms an upper lap;
wherein the upper mat and the lower mat are comprised of tire treads obtained from used tires; and
wherein an unattached portion of one of the first lower tire section or second lower tire section forms a lower lap.
