SMM (Stabilized Mulch Matrix)- A hydraulically-applied matrix containing defibrated organic fibers with, at a minimum, one of the following additives: soil flocculants, crosslinked hydro-colloidal polymers, tackifiers. Utilized to provide erosion control and facilitate vegetation establishment on moderate slopes and designed to be functional for a minimum of 3 months. BFM (Bonded Fiber Matrix)- A hydraulically-applied matrix containing organic defibrated fibers and cross-linked insoluble hydro-colloidal tackifiers to provide erosion control and facilitate vegetation establishment on steep slopes and designed to be functional for a minimum of 6 months. FRM (Fiber Reinforced Matrix)- A hydraulically-applied matrix containing organic defibrated fibers, cross-linked insoluble hydro-colloidal tackifiers, and reinforcing natural and/or synthetic fibers to provide erosion control and facilitate vegetation establishment on very steep slopes and designed to be functional for a minimum of 12 months. Rolled Erosion Products RECP (Rolled Erosion Control Product) - A temporary degradable or long-term non degradable material manufactured or fabricated into rolls designed to reduce soil erosion and assist in the growth, establishment and protection of vegetation. Ultra-Short Term Products - An RECP designed to last three months or less. They are used in areas where vegetation can be quickly established and will be mowed soon after installation. The netting and bonding materials (e.g. stitching thread) on ultra-short term products degrade quickly to prevent entanglement with mowing equipment. Short-Term Products - An RECP designed to provide erosion protection for longer than three months and up to 12 months. This is basically one growing season for the establishment of vegetation. Extended-Term Products - An RECP designed to provide erosion protection for longer than 12 months and up to 24 months. These products are used in areas where vegetation establishment may take up to two full growing seasons. These products are often used in semi-arid locations. Long-Term Products - An RECP designed to provide erosion protection for longer than 24 months and up to 36 months. Long-Term Non-Degradable - An RECP composed of non-degradable materials that furnishes erosion protection and extends the erosion control limits of vegetation for the design life of a project. ECB (Erosion Control Blanket) - A temporary degradable rolled erosion control product composed of processed natural or polymer fibers mechanically, structurally or chemically bound together to form a continuous matrix to provide erosion control and facilitate vegetation establishment. Temporary Rolled Erosion Control Products - For applications where natural vegetation alone will provide sufficient permanent erosion protection, furnish a temporary rolled erosion control product with the necessary longevity and performance properties to effectively control erosion and assist in the establishment of vegetation under the anticipated immediate site conditions. Permanent Rolled Erosion Control Products - For applications where natural vegetation alone will not sustain expected flow conditions and/or provide sufficient long-term erosion protection, furnish a permanent rolled erosion control product with the necessary performance properties to effectively control erosion and reinforce vegetation under the expected long-term site conditions. TRM (Turf Reinforcement Mat) - A rolled erosion control product composed of non-degradable synthetic fibers, filaments, nets, wire mesh and/or other elements, processed into a permanent, three-dimensional matrix of sufficient thickness. TRMs, which may be supplemented with degradable components, are designed to impart immediate erosion protection, enhance vegetation establishment and provide long-term functionality by permanently reinforcing vegetation during and after maturation. Note: TRMs are typically used in hydraulic applications, such as high flow ditches and channels, steep slopes, stream banks, and shorelines, where erosive forces may exceed the limits of natural, unreinforced vegetation or in areas where limited vegetation establishment is anticipated. Miscellaneous NPDES - National Pollutant Discharge Elimination System NTPEP - National Transportation Product Evaluation Program Tensile Strength - The resistance to deformation developed for a specific material and subsequent modulus and elongation when subjected to tension by an external force. |
