VIII. BONDED FIBER MATRIX (B.F.M.) SPECIFICATION

Pub 408 Section 805.2(a)MATERIAL

1.e Bonded Fiber Matrix (BFM).

Specially prepared, water soluble, biodegradable, hydraulically appliedsystem of long strand wood fibers held together by a bonding agent, which adheres to the soil surface and upon dryingforms a continuous, insoluble, three dimensional, non-dispersible protective crust-like soil covering.

1.e.1 Polymer or Hydrocolloid Binder Matrix.

1.e.1.a Wood Fiber.

Specially prepared, long strand (min. 25% 3/8-inch length), air-dried wood fibers(88% to 92% by weight) manufactured from wood chips, bark, or clean wood waste products, and conforming to thefollowing requirements:

Moisture content 15% maximum

Water holding capacity 1000 minimum

(Grams of water per 100 grams of fiber)

1.e.1.b Bonding Agent.

High-strength tackifier of powdered polysaccharide guar gum, blendedhydrocolloid-based binder, hydrophilic, or co-polymer material 5 to 12% by weight.

1.e.1.c Synthetic Fiber.

System may contain up to 5% by weight of crimped, polyester fibers or othersynthetic fibers with wetting and dispersion agents manufactured for use in mulching applications.

1.e.1.d Dye.

System may contain a nontoxic, water soluble, colored dye to aid in the visual applicationcoverage of the matrix.

1.e.1.e Activator.

System may contain up to 1% by weight of organic and mineral fertilizers

Moisture content 15% maximum

Water holding capacity 1000 minimum

(Grams of water per 100 grams of fiber)

1.e.2.b Bonding Agent.

Naturally occurring, high purity, processed hemi-hydrate gypsum withmanufacturer's system additives, which when combined with water will form a cementitious binder that will produce

a crust-like soil covering within 4 to 8 hours after application. Material that has become partially air set, lumpy, orcaked before use is not acceptable for use.

System may contain a nontoxic, water soluble, colored dye to aid in the visual applicationcoverage of the matrix.

805.3 CONSTRUCTION.

(e) Bonded Fiber Matrix.

1. General.

Prepare surfaces as specified in Section 804.3(b). Scarify all slopes greater than 3:1 to ensure a

rough texture for lodging of seed and BFM. Apply seed at twice the rate specified in Section 804.2(b)2 Table A. Apply

soil supplements as specified in Section 804.3(c).

Page 6 0f 9

2. Application.

  • Apply bonded fiber matrix components hydraulically with hydromulching (hydroseed)equipment manufactured for this

purpose. Follow manufacturer's mixing and application instructions.

  • The bonded fiber matrix components may be incorporated as an integral part of the seeding and soil supplementapplication if seeding and soil supplements are applied hydraulically.
  • Apply polymer binder or hydrocolloid binder matrixes at an application rate of 3,000 pounds per acre or asindicated to provide a uniform soil surface coverage thickness of 0.16-inch maximum after drying. Test applicationprocedures to ensure a uniform application rate. Do not apply within 24 hours of anticipated rainfall.
  • Mix gypsum binder matrix components in a homogenous slurry in the following proportions for each 100 gallonsof water: gypsum binder—150 pounds; wood fiber—40 pounds; and synthetic fiber—0.6 pounds. Apply gypsumbinder matrix at an application rate of 6,000 pounds per acre or as indicated so that the soil surface is covereduniformly. Do not apply within 12 hours of anticipated rainfall.
  • Place BFM material at least 18 inches beyond the toe and top of all slopes. Apply material indirections to provide as much uniform coverage with no gaps or spaces greater than 0.04 inch.

805.4 MEASUREMENT AND PAVEMENT
