  • Patent number: 6372069
    Abstract: A method for utilizing discarded tires is disclosed which creates strong, durable, posts, beams, mats, blocks or other structures. Used tires are cut and flattened and the sidewalls are removed. The tread sections of the tires are cleaned. Vulcanizing compound is then applied to adjacent inner surfaces of the tread sections to form a flat essential building element. These building elements may be vulcanized together in alternating horizontal and perpendicular layers to form flat blocks, mats, noise or safety barriers, or other structures. The essential building elements are flat and form structures which have flat upper and lower surfaces and a rectangular cross-section. Beams may be formed by securing a number of the essential building elements together to form structures that are approximately 8 feet high and have a rectangular cross-section.
