Abstract

Abstract A stable artificial putting green which includes a base, an intermediate layer, an artificial putting surface including a pile fabric supported by the intermediate layer, and an edging defining its outer limits. The pile fabric extends over the upper edge and down an outer side of the edging where it is secured. Fine sand fills the interstices about the pile yarns. The intermediate layer includes a PYRACELL layer. The PYRACELL layer includes a synthetic sheet formed with a plurality of raised conically shaped hollow cells over its upper surface. A plurality of drainage holes are formed in spaces between the cells and a non-wove porous web is secured to the lower surface of the sheet. Finally, a coarse sand is laid over the sheet up to substantially top surfaces of the cells.
