Bonded Fibre Matrix (BFM) mulch is a type of hydroseeding erosion control product.[1]
The matrix is a continuous layer of elongated fibre strands held together by a water-resistant bonding agent. It keeps raindrops from hitting the soil because it has no holes larger than one millimetre. It allows no gaps between the product and the soil.[2] It has a high water-holding capacity. It will not form a water-insensitive crust that can inhibit plant growth. It biodegrades into materials that help plant growth.
