An underlayment includes a base layer having a base elevation and a series of individual supports extending upwardly from the base layer and being configured to create voids in a layer of bonding material used to adhere the veneer material to the underlayment. Each of the individual supports includes: at least one outer wall extending upwardly from the base layer and terminating at an upper lip, a bowl area defined adjacent a center of each of the individual supports and having a foot support defined at a bottom of the bowl area; and an internal wall extending downwardly and inwardly from the upper lip toward the foot support. An elevation of the foot support is substantially the same as an elevation of the base layer immediately adjacent the outer wall of each of the individual supports.
