This document specifies a permanent Geosynthetic Turf Reinforcement Mat (TRM) with Flexible Growth Medium (FGM) infill, to prevent long-term soil and vegetation loss resulting from excessive water flow (velocity and shear stress) in which unreinforced vegetation could not resist. The FGM provides immediate and temporary protection against movement and/or loss of soil until vegetation can be established. The FGM infill also provides an ideal environment for rapid seed germination and accelerated plant and root establishment within the matrix of the TRM.
