1. A method of making a carpet tile, comprising:
(a) extruding an adhesive composition onto a back surface of a primary backing component of a greige good, the greige good further comprising a plurality of fibers attached to the primary backing component and extending from a face surface of the primary backing component; and
(b) laminating a reinforcement material onto the adhesive composition, wherein the reinforcement material has an open structure and opposed first and second sides that are spaced apart relative to a vertical axis, the open structure comprising a porous structure, a plurality of through-openings, or an open-mesh structure;
(c) allowing the adhesive composition to flow through the open structure of the reinforcement material from the first side of the reinforcement material to the second side of the reinforcement material; and
(d) cooling the adhesive composition to define an adhesive layer comprising the adhesive composition and the reinforcement material, wherein the reinforcement material is at least partially embedded within the adhesive composition,
wherein the adhesive composition is applied to the back surface of the primary backing component and defines at least a portion of a first side of the adhesive layer, and wherein the reinforcement material and the adhesive composition each define respective portions of a second side of the adhesive layer opposite the first side of the adhesive layer.
