The North American Green P300 permanent turf reinforcement mat shall be constructed of 100% UV stabilized
565 denier polypropylene fiber sewn between a black UV stabilized 0.50 x 0.50 inch (1.27 x 1.27 cm) mesh
polypropylene netting on the top (5 lbs /1,000 frl) and a black UV stabilized 0.625 x 0.625 inch (1.59 x 1.59 cm)
mesh polypropylene netting on the bottom (3 lbs /1,000 f°). The P300 is sewn together using UV stable
polypropylene thread stitched on 1.50 inch (3.81 cm) centers. The mat is highly resistant to ultraviolet and
biological degradation. The following list contains further physical properties of the P300 erosion control/turf
reinforcement mat.

tBench Scale Performance Testing
Bench scale tests are index property tests. These tests are not indicative of field performance and therefore should
not be used in design to establish performance levels for rolled erosion control products. Bench scale tests are
• performed according to methods developed by the Erosion Control Technology Council (ECTC).
