The P300 permanent turf reinforcement mat shall be amachine-produced mat of 100% UV stable polypropylene fiber.
The matting shall be of consistent thickness with synthetic fibers evenly distributed over the entire area of the mat. The
matting shall be covered on the top with black heavyweight UV stabilized polypropylene netting having ultraviolet
additives to prevent breakdown and an approximate 0.50 x 0.50 inch (1.27 x 1.27 cm) mesh size. The bottom net shall
also be UV stabilized polypropylene, with a 0.625 x 0.625 inch (1.57 x 1.57 cm) mesh size. The matting shall be sewn
together on 1.50 inch (3.81 cm) centers with UV stabilized polypropylene thread.
The P300 shall meet requirements established by the Erosion Control Technology Council (ECTC) Specification and
the U.S. Department of Transportation, Federal Highway Administration's (FHWA) Standard Specifications For
Construction of Roads and Bridges on Federal Highway Projects, FP-03 2003 Section 713.18 as a Type SA or B

The P300 is also available upon request with the DOT SystemTM. The DOT SystemTM consists of installation staple
patterns clearly marked on the erosion control blanket with environmentally safe paint. The blanket shall be
manufactured with a colored line or thread stitched along both outer edges (approximately 2-5 inches [5-12.5 cm] from
the edge) to ensure proper material overlapping.
The turf reinforcement mat shall be P300 as manufactured by North American Green, or equivalent.
