1. A floor covering tile comprising:
a top surface of the floor covering tile;
a bottom surface of the floor covering tile;
a planar backing layer comprising:
a first surface;
a second surface opposite the first surface;
a length; and
a width perpendicular to the length, the length and width defining an area of the first surface of the planar backing layer, wherein the first surface of the planar backing layer faces the bottom surface of the floor covering tile; and
a fibrous textile face layer having top face and a bottom face, wherein the bottom face of the fibrous textile face layer is attached to the second surface of the planar backing layer and the top face of the fibrous textile layer faces the top surface of the floor covering tile; and
an adhesive layer disposed between the fibrous textile face layer and the planar backing layer,
wherein a plurality of zones are disposed across the area of the first surface of the planar layer, each zone occupying a portion of the area and comprising a variation in at least one physical property along the length or the width of the planar backing layer to counteract warping due to changes in temperature and humidity of the face layer and the planar layer, and
wherein each zone occupies an equal portion of the area of the first surface of the planar backing layer and comprises an identical shape.
