Abstract:
1. A method of producing a static resistant synthetic inter-connectable structural mat for supporting vehicles, heavy equipment, and drilling rigs, and for resisting static charge and corrosive materials, wherein the static resistant synthetic inter-connectable structural mat is transportable using conventional trucks on conventional roadways, the method comprises: a. positioning a plurality of static resistant structural boards parallel to each other and spaced from ¼ of an inch to ¾ of an inch apart, as bottom structural boards in a first orientation, and extending alternating bottom structural boards to extend beyond an adjacent bottom structural board, forming a plurality of identical length openings between adjacent bottom structural boards opposite the extended bottom structural boards; b. positioning a plurality of static resistant structural boards parallel to each other and spaced from ¼ of an inch to ¾ of an inch apart, as middle structural boards in a second orientation over the bottom structural boards, wherein the second orientation is at a 90 degree angle to the first orientation, and wherein the middle structural boards do not extend over the extending bottom structural boards; c. positioning a plurality of static resistant structural boards parallel to each other and spaced from flush to each other to ¾ of an inch apart, as top structural boards in the first orientation over the middle structural boards, wherein the top structural boards do not extend over the extending bottom structural boards; and d. securing the top structural boards and the middle structural boards to the bottom structural boards using lag screws providing a static charge conduit from each top structural board to a ground, thereby forming a static resistant synthetic inter-connectable structural mat, wherein each of the bottom layer of structural boards, the middle layer of structural boards, and the top layer of structural boards are formed by the method:
