Permanent Turf Reinforcement Mat : Vmax3 P550
North American Green’s P550 is made of a permanent, ultra-high-strength, three-dimensional matting structure incorporated with a permanent 100% polypropylene fibre matrix. The 100% polypropylene fibre matrix enhances the permanent matting structure ’s initial mulching and erosion control properties, as well as its permanent vegetation reinforcement capabilities.
P550 is designed to provide long-term, pre-vegetated erosion protection and permanent turf reinforcement in an extensive range of severe applications that include extreme-flow channels, spillways, stream banks, and shorelines. P550 is proven to drive the shear resistance of vegetation to over 672 Pascal—a new maximum for vegetation reinforcement.

P550 Performance Profile
Phase 1
(unvegetated)
Unprotected seed and soil are highly susceptible to erosion. Upon installation, the P550’s polypropylene fibre 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 191 Pascal or up to 3.8 m/s flow velocity!
Phase 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 29 Pascal.* The P550 continues providing erosion protection between, and structural support for, developing plants – increasing the permissible shear stress of new vegetation up to 576 Pascal.
Phase 3
(vegetation maturity)
Under flow-induced shear stress of only 48 Pascal, un-reinforced mature vegetation may allow significant soil loss and experience physical damage.** The P550 reinforces soils and anchors vegetation roots and stems – increasing the permissible shear stress of the permanent vegetative stand up to 672 Pascal or flow velocities up to 7.6 m/s!
