C350 In Action!
Phase 1Phase 1
Unvegetated

Unprotected seed and soil are highly susceptible to erosion. Upon installation, the C350’s coconut fiber matrix and corrugated matting structure provide a uniform mulch layer and effective erosion protection for seed and soil under flow-induced shear stresses up to 3.2 lbs / ft2 (153 Pa). 		Phase 2Phase 2
Vegetation Establishment

The tender stems and undeveloped root systems of immature vegetation provide little protection for the soil surface and are prone to damage or removal at shear stresses of only 0.6 lb / ft2 (29 Pa).* The C350 continues providing erosion protection between, and structural support for, developing plants – increasing the permissible shear stress of new vegetation up to 10 lbs / ft2 (480 Pa).		 Phase 3Phase 3
Vegetation Maturity

Under flow-induced shear stress of only 1.0 lb / ft2 (48 Pa), unreinforced mature vegetation may allow significant soil loss and experience physical damage.** The C350’s corrugated matting structure reinforces soils and anchors vegetation roots and stems – increasing the permissible shear stress of the permanent vegetative stand up to 12 lbs / ft2 (576 Pa).

* Based on FHWA HEC#15 Permissible Shear Stress for Class D Vegetation [2 – 6” tall (5 – 15 cm), fair stand].
** Based on FHWA HEC#15 Permissible Shear Stress for Class C Vegetation [6” tall (15 cm), good stand].
