ABSTRACT:
A stabilized sand surface for tennis courts is formed of a thick, densely tufted, coarse, synthetic fiber carpet which is covered with a single layer of fine, dry, silica sand. The carpet tufts each comprise numerous, closely packed, resilient, somewhat twisted strands of substantially equal length, which are tufted to a resilient carpet base sheet so that the strands tend to intertwine, but extend generally upright from the sheet. The sand layer covers the carpet and fills the interstices from the base sheet to substantially the full height or a little below the full height of the strands. The sand covering layer is stabilized by the mat-like network formed of the closely packed, intertwined, resilient strands against substantial permanent shifting or wind loss, while being relatively yieldable under impact of the tennis ball to produce a playing surface which simulates the playing quality of a clay-type tennis court surface.
