The composite turf reinforcement mat (C-TI2NI) shall be a machine produced mat of 100% coconut fiber matrix incorporated into a permanent $uee-dimensional netting structure. The matrix shall be evenly distributed across the entire width of the matturg and stitch bonded between a heavy duty iJV stabilized bottom net with 0.50 x 0.50 inch (1.27 x 1.27 cm) openings, a super heavy duty I1V stabilized, dramatically corrugated (crimped) middle netting with 0.50 x 0.50 inch (1.27 x 1.27 cm) openings, and a heavy duty W stabilized top net with 0.50 x 0.50 inch (1.27 x 1.27 cm) openings. The corrugated netting shall form prominent closely spaced ridges across the entire width of the mat. The three nettings shall be stitched together on 1.50 inch (3.81 cm) centers with L1V stabilized polypropylene thread to form a permanent three-dimensional structure. All mats shall be manufactured with a colored thread stitched along both outer edges (approximately ~5 inches [5- 12.5 cm] from the edge) as an overlap guide for adjacent mats. The composite turf reinforcement mat shall be the North American Crreen C350, or equivalent. The C350 permanent composite turf reinforcement mat shall have the following physical properties: Material Contenf Matrix 100% Coconut Fiber (0.50 lb/yd') (0.27 kg/m~ Netting Top - Heavy IJV Stabilized Polypropylene 8.00 lbs/1,000 ft' (3.91 kg/100 m~ approximate weight Mid -Super Heavy W Stabilized Polypropylene Corrugated 24 Ib/1,000 ft' (11.7 kg/100 m~ approximate weight Bottom - Heavy W Stabilized Polypropylene 8.00 Ibs/1,000 ft' (3.91 kg/100 m~ approximate weight Thread Black UV Stabilized Polypropylene Physical Specifications (per roll) En Metric Width 6.50 ft 2.00 m Length 55.50 ft 16.90 m Weight 37.00 lbs f 10% 16.80 kg Area 40.00 yd' 33.40 m' Stitch Spacing 1.50 in 3.81 cm
