Abstract
Various embodiments for a pad that may be combined with other similar pads to form a padding layer of an athletic field, or other surface, are disclosed. The pad includes a top surface and a bottom surface. Bottom-side projections are positioned on the bottom surface of the pad. Water channels are positioned on the bottom surface of the pad defined as a recessed area between individual ones of the bottom-side projections. A drainage hole is positioned in at least one of the bottom-side projections such that the drainage hole does not connect with any of the water channels on the bottom surface. The drainage hole may be at least partially coupled to projection channels on the bottom-side projections, where the projection channels act as a water vacuum to facilitate air circulation and vertical water evacuation relative to the drainage hole.
