A durable and wear resistant synthetic sports field having at least one strip having a plurality of fibrillated polypropylene strands tufted within a multilayer backing material. The strands are tufted in a wide variety of pile heights, patterns, gauges, and stitch patterns depending upon end use. The multiplayer backing material has a top mesh polypropylene layer at least three layers of a backing material coated with a secondary coating used to contain the ends of the plurality of strands. The strips are placed onto a fine aggregate layer placed over a coarse aggregate layer and a geotextile fabric. The geotextile fabric is placed onto a compacted and leveled subgrade. A ground rubber infill, with or without sand particles and diatomaceous earth, is introduced onto the strips. In alternative arrangements, a series of perforated drains and drain tiles may be introduced to the coarse aggregate layer to promote drainage.
