I II I I I I I I I I I I I I I I I I I Bonded Fiber Matrix Specification The Bonded Fiber Matrix, (BFM), shall be hydraulically applied and upon drying, adhere to the soil in the fOIm of a continuous, 100"10 coverage biodegradable erosion control blanket. Material Properties: The Bonded Fiber Matrix shall be yellow in color, comprised oflong strand, thermally defibrillated wood fibers, passing a Freeness test at a 760 cc (MLS) level or below). The wood fibers (>88% total volume by weight) shall beheld together by organic tackifiers, (10"10), and mineral bonding agents, (<2%), which upon drying, become insoluble and non-disperstble. The matrix which fonns shall be designed, tested and proven to perfOIm in a manner equal or superior to biodegradable erosion control blankets, (ECBs). Documentation of testing at an industry recognized laboratory shall be provided which demonstrates superior performance as measured by reduced water runoff; reduced soil loss, and better plant germination, as compared to erosion control blankets. The fonned matrix shall meet the following performance requirements: 1. The material, when mixed into a liquid slurry, shall pass a free liquid quality control test, Qiquids separate from fibrous solids, no greater than 1" in 1 minute's time, as measured on a standard test board). 2. The matrix, when dry, shall not dissolve or disperse upon rewetting. 3. The matrix shall have no holes> Imm in size. 4. The matrix shall have no gaps between the product and the soil. 5. The matrix shall have a minimum water holding capacity ofI,OOOg/I00b, (1.2 gal/IB matrix). 6. The matrix shall have no germination or growth inhibiting components, and shall not fOIm a crust which inhibits water infiltration. 7. The matrix shall be comprised of materials which are 100"10 biodegradable and 100"10 beneficial to plant growth. Installation: The Bonded Fiber Matrix, (BFM), shall be installed by a contractor certified by the IIIlIIlI1fiIctu and trained in the proper procedures for mixing and application of the product. The BFM shall be mixed according to lTIarnrl'acturer's recommendations, (125 gal water/50 LB bag, 48kg BFM/kl water), and contractor shall demonstrate "free liquid" test to inspector upon request. Bonded Fiber Matrix shall be spray applied at a rate of3,OOO - 3,800 LB/acre, [3,400 - 4,300 kg BFM fiber/hectare, (SI Unites)], utilizing standard hydraulically seeding equipment. The BFM shall be applied in successive layers, with sufficient BFM material as to achieve 100"10 coverage of all exposed soil. The BFM shall not be applied over standing water, nor immediately before, during, or immediately after rainfiill. The matrix shall have the opportunity to dry for 24 hours after installation, with exceptions approved by the engineer. 1 Il~A\IlllFFALO.tom<:_41AM)
