nl P55O
The composite turf reinforcement mat (C-TRM) shall be a Wtachine-produced mat of 100% UV stabilized polypropylene
fiber matrix incorporated into a permanent three-dimensional turf reinforcement matting.
The matrix shall be evenly distributed across the entire width of the matting and stitch bonded between the bottom and
middle uhra heavy duty UV stabilized Wettings with 0.50 x O.SO inch (1.27 x 1.27 cm) openings and then covered by an
ultm heavy duty UV stabilized Wettings with O.SO x 0.50 inch (1.27 x 1.27 cm) openings. The middle, dramatically
corrugated (crimped) netting shall form prominent closely spaced ridges across the entire width of the mat The three
Wettings shall be stitched together on 1.50 inch (3.81 cm) centers with UV stabilized polypropylene thread to form a
