Bonded Fiber Matrix

Erosion Control BFM

What is This Treatment?

Bonded fiber matrix consists of a wood or wood/paper fiber blanket bonded together by a polymer tackifier.

The Bonded Fiber Matrix specification includes the following steps:

  1. A hydroseed truck sprays wood fiber and tackifier from one direction.
  2. A hydroseed truck sprays wood fiber and tackifier from a second direction.

When to Use This Treatment:

  • Use for cut and fill slopes and other disturbed soil areas.
  • Typically used to treat disturbed areas larger than 0.5 acres. Consider using Dry Seeding to hand-seed areas less than 0.5 acres.

Benefits:

  • Immediate protection from surface erosion due to raindrop impact (after 24-48 hour cure period).

  • Conforms closely to the soil surface which may result in less erosion due to surface rilling.

  • Vegetation provided by seed provides long-term control of erosion.

Limitations:

  • Higher application rates required for steeper slopes may inhibit germination of seed and establishment of long-term vegetation.
  • Surface treatment only - unlikely to improve compacted, nutrient depleted, or poorly draining soils as necessary to ensure vigorous long term vegetative cover.

  • Inefficient technique to treat disturbed areas less than 0.5 acres. Consider using the Dry Seeding specification instead.

Consider Using With:

To effectively treat sites where Erosion Control (Bonded Fiber Matrix) may not stay in place, consider combining this treatment with:

To effectively treat sites with poor soils (compacted, nutrient depleted, or poorly draining), consider combining this treatment with:
