Application Rates and Loading Procedures

Material:
The bonded fiber matrix (BFM) shall be designed for application by conventional hydroseeding
equipment and contain a blend of paper, thermally heat treated cellulosic fiber mulch (paper/soft
wood), cross linked hydrocolloid tackifier, fiber-reinforced gypsum pre-mix that upon drying, forms
a breathable, built-in-place, protective blanket that reduces water and wind induced erosion. The
gypsum content will act as a binder initially, and then slowly degrade with exposure to the
elements, gradually releasing calcium and sulfur nutrients to plants and soils. This side benefit is
not intended to be an integral part of your soil fertility program. The bonded fiber matrix product
shall be non-toxic and biodegradable.

Purpose:

• To minimize erosion and to hold soil in place temporarily
• To allow time for the establishment of grass or other plants for permanent erosion control
• To hold seed in place and optimize growth conditions


Typical Application Rate:

<3:1 slope - 3000 lbs/ac
3:1 to 2:1 - 3500 lbs/ac
