Hydroseeding & Erosion Control Hydroseeding is known in the industry to be a viable solution for erosion problems during grass establishment. Hydroseeding uses a BFM mulch mix. What is a BFM? A BFM (Bonded Fiber Matrix) is a hydraulically applied product which is designed, tested and proven to match or exceed the performance of erosion control blankets. Once applied, it forms a continuous layer of elongated fiber strands held together by a water-resistant bonding agent. It eliminates direct rain drop impact on soil (it has no holes greater than one millimeter in size), it allows no gaps between the product and the soil and it has a high water-holding capacity. A bonded fiber matrix will not form a water-insensitive crust that can inhibit plant growth and it biodegrades completely into materials known to be beneficial to plant growth. The benefits of hydroseeding with a BFM are unsurpassed.
