Adhesive-backed flooring panel, system, and method

An adhesive-backed flooring panel comprising:

• a flooring panel body comprising a) one or more base layers containing a polymer material and a filler, wherein the polymer material comprises a thermoplastic polymer, a thermoset polymer, or blends of polymers, and said flooring panel having a top surface, a bottom surface, and a perimeter edge, and exhibiting a flexural rigidity such that the flooring panel body cannot be rolled-up and the top surface cannot contact the bottom surface and said adhesive-backed flooring panel body having a cross-sectional area;
• and
• b) a double-sided adhesive sheet adhered to and covering the bottom surface of the flooring panel body and comprising
• a base sheet having a first surface and a second surface opposite the first surface, wherein the base sheet comprises a moisture barrier material exhibiting a water vapor permeance of 1 perm or less when tested in accordance with ASTM E96,
• a first adhesive layer adhered to the bottom surface of the flooring panel body and the first surface of the base sheet, and
• a second adhesive layer having an inner surface and an outer surface opposite the inner surface, wherein the inner surface is adhered to the second surface,
• wherein the first adhesive layer, the second adhesive layer, or both, comprises a dry adhesive and wherein a thickness of the double-sided adhesive sheet is not greater than 300 microns and wherein the double-sided adhesive sheet covers at least 90% of the cross-sectional area of the bottom surface of the flooring panel body, and wherein said adhesive-backed flooring panel is in the absence of any mechanical fasteners and tongue/grooves.
