Abstract
The flooring structure of this invention controls electrostatic charges. The normal presence of moisture will not affect the flooring structure's ability to control electrostatic charges. A moisture detector circuit will, however, indicate the presence of moisture, and can activate means for drying this moisture. The resistance of the flooring structure can be adjusted so that electrostatic charges are dissipated at different rates. Multiple flooring structures with different resistance values can be placed side by side.
