BONDED FIBER MATRIX
What is a Bonded Fiber Matrix?
Bonded Fiber Matrix is a new class of erosion control products, pioneered by Weyerhaeuser with the introduction of Soil Guard®. The term is being accepted within the erosion control industry to categorize hydraulically applied products which are designed, tested and proven to match or exceed the performance of erosion control blankets. Soil Guard® is now being manufactured by Mat, Inc., our supplier of wood fiber products. Mat has purchased the technology from Weyerhaeuser and is making this fine product.
A bonded fiber matrix is 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 does not allow 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 will biodegrade completely into materials known to be beneficial to plant growth.
Soil Guard® bonded fiber matrix is designed, tested and proven to meet these criteria. No other product currently meets these standards. In addition, Soil Guard®'s performance has been demonstrated to be superior to that of erosion control blankets.
What is Not a Bonded Fiber Matrix?
Other erosion control products can be combined to imitate a bonded fiber matrix. The resulting mixture will share some characteristics with Soil Guard®. However, no such combination currently available is designed, tested or proven as a bonded fiber matrix. None have demonstrated the same high performance standards as Soil Guard®.
