Abstract: 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.

Abstract: A drainage system for a synthetic sports field is disclosed that substantially prevents the leeching of specific contaminants from surface runoff water from entering into water tables or sewer systems associated with the drainage of the synthetic sports field. The drainage system includes a containment system and filtration system located beneath the synthetic sports field for directing rainwater through a series of drains and filters prior to being exposed to either the sewer system or water table. In this way, environmental concerns associated with the drainage of synthetic sports fields is alleviated.
