1. A laminated dry floor system comprising:
a grid having a lattice of intersecting members forming a first array of apertures, where each of the intersecting members have a tapered cross section that is triangular with an upper apex having a height (H) and sloping side surfaces extending from the upper apex to a base surface of the grid to define a base angle (θ), such that each aperture of the first array is defined by a width (W) between the upper apexes of the intersecting members; and a width (W′) between the intersecting members proximate the base surface of the grid, wherein W is greater than W′;
a support interlayer adhered at an upper surface beneath the grid to a base surface of the grid and having a second array of apertures in concentric alignment with the first array of apertures, where the first array of apertures, second array of apertures and thickness of the support interlayer configured to induce passage of a liquid, W is approximately 0.27 inches, and W′=W−(2(H/tan θ));
a wicking layer in contact with a lower surface of the support interlayer opposite the grid;
wherein the support interlayer and associated bond lines between the grid and support interlayer and between the support interlayer and wicking layer have a thickness (T) which assures contact betweent an upper surface of the wicking layer and a catenary surface of a water droplet held in the first and second array of apertures by surface tension where T≤0.030 inches;
a base layer underlying the wicking layer; and
a pan assembly configured to receive the base layer.
