  • Publication number: 20060029472
    Abstract: The present invention is directed to a subsurface drainage system for a playing surface. The subsurface drainage system includes a subgrade, an intermediate layer disposed over the subgrade, a layer of semi-permeable filter fabric disposed over the intermediate layer, an upper permeable layer disposed over the layer of filter fabric and on which the playing surface is disposed, and a hydronic piping network disposed in the upper layer near the layer of filter fabric. The layer of filter fabric has a permeability less than the permeability of the intermediate layer and such that the layer of filter fabric functions as a perching layer to support a perched water table above the filter fabric. The hydronic piping network is positioned within the perched water table such that the water of the perched water table functions as a heat exchanger to facilitate heating and cooling of the upper layer upon the hydronic piping network being heated or cooled.
