Erosion Control Blankets, Excelsior
|
Straw Blanket
Straw blankets were for moderate to steep slopes and low-flow channels where erosion protection is required for only a short period during vegetation development. The blankets are reinforced by a light weight photodegradable net with a uniform wheat straw filler for soil erosion control and seed bed mulching. Straw blankets offer an economic advantage over excelsior blankets.
Standard Straw Blanket: This straw blanket has only one side of netting stitched on 1.5" centers with an average shear stress of 1.60 lb./ft.
High Velocity Straw Blanket: This straw blanket has two sides of netting stitched on 1.5" centers with an average shear stress of 2.25 lb./ft. |

Standard color is a natural brown with an option for green on most products.

Make sure the blanket is in contact with the soil over the entire area, and secured with staples. Normally, it is not necessary to overlap, dig check slots, anchor ditches or bury ends of the blanket when using XCEL Temporary ECB's. It may be necessary to dig check slots, anchor ditches or bury ends of the blanket on long slopes or high flow channel conditions.
