PRIMARY USE:
Erosion control blankets are designed to hold seed and soil in place until
vegetation is established on disturbed areas. They can be used on any
disturbed areas, but are particularly effective for slopes and embankments.
When used in combination with sediment trapping BMPs such as silt fence or wattles, blankets may be used as a perimeter control with or without vegetation
DESIGN CRITERIA:
The type and class of erosion control mat must be specified as appropriate
for the slope of the area to be protected and the anticipated length of
service.
ECBs should meet the applicable “Minimum Performance Standards for
TxDOT” as published by TxDOT in its “Erosion Control Report” and/or be
listed on the most current annual “Approved Products List for TxDOT”
applicable to TxDOT Item 169 Soil Retention Blanket and its Special
Provisions.
Prior to the installation of any erosion control matting, all rocks, dirt clods,
stumps, roots, trash and any other obstructions that would prevent the mat
from lying in direct contact with the soil shall be removed. Anchor trenching
shall be located along the entire perimeter of the installation area, except
for small areas with less than 2% slop
Installation and anchoring shall conform to the recommendations shown
within the manufacturer's published literature for the approved erosion
control blanket. Particular attention must be paid to joints and overlapping
material.
After appropriate installation, the blankets should be checked for uniform
contact with the soil; security of the lap joints, and flushness of the staples
with the ground.
