Erosion control blankets

D6459 Erosion control blanket performance in protecting hillslopes from rainfall-induced erosion... 

Erosion control blankets are used on slopes and disturbed soils where mulch must be anchored and other methods such as crimping or tackifying are neither feasible nor adequate. They are used on steep slopes, generally steeper than 3 1, and slopes where erosion hazard is high their use is especially appropriate for critical slopes adjacent to sensitive areas, such as streams and wetlands, and disturbed soil areas, where planting is likely to be slow in providing adequate protective cover. 

Erosion control blankets Low to moderate cost easy to install good moisture absorption very low sediment yield very good vegetative density Temporary (1—3 years) low to moderate flows Netting may interfere with maintenance (if improperly inadequately anchored)...
