MATERIAL SPECIFICATION
AMER CAN C350
GREEN°
•
The composite turf reinforcement mat (C-TRNl) shall be amachine-produced mat of 100% coconut 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 a super heavy
duty UV stabilized bottom net with 0.50 x 0.50 inch (1.27 x 1.27 cm) openings, anultra-heavy duty UV stabilized,
dramatically corrugated (crimped) intermediate netting with 0.50 x 0.50 inch (1.27 x 1.27 cm) openings, and covered
by a super heavy duty UV 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 UV stabilized polypropylene thread to form a permanent three-
dimensional turf reinforcement matting.
The C350 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, B, and C
Permanent Turf Reinforcement Mat.
Installation staple patterns shall be clearly marked on the turf reinforcement matting with environmentally safe paint.
All mats shall be manufactured with a colored thread stitched along both outer edges (approximately 2-5 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 Green C350, or equivalent.
composite turf reinforcement mat shall have the following physical properties:
