1. Preparation

• Clear the Channel: Remove any debris, rocks, or vegetation from the channel bed and sides. Ensure the area is smooth and free of large obstructions.

• Grade the Channel (if necessary): If the channel isn't properly graded, ensure a consistent flow path is created, and the slope is uniform for the erosion control blanket to function properly.

• Check Soil Conditions: The soil should be firm and compacted. If it's loose or uneven, rework the soil to create a better base for the blanket.

2. Unroll the Blanket

• Position the Blanket: Begin at the upstream or uppermost point of the channel. Unroll the blanket lengthwise in the direction of the water flow.

• Ensure Proper Orientation: The blanket should be unrolled parallel to the direction of flow. Ensure it fits tightly to the channel bed and sides.

• Overlap Sections: When overlapping multiple blankets, allow a 3-6 inch overlap to prevent any gaps between sections. This ensures water doesn’t erode beneath the blanket.

3. Securing the Blanket

• Staking: Secure the blanket using stakes. Insert these at regular intervals:

  • Every 2 feet along the edges.

  • Every 3 feet across the blanket, focusing more around edges and seams.

  • Change the stake pattern based on med. to high or high flow channels seen below:​

• • Drive Stakes at an Angle: Make sure the stakes are driven at a 45-degree angle to properly anchor the blanket into the ground.

  • Anchor the Blanket at the Inlet and Outlet: Use extra stakes around the channel inlet (upstream) and outlet (downstream) areas, as these are high-stress points.
     

4. Securing the Edges

• Edge Stakes: Place stakes every 6-12 inches along the edges to ensure the blanket doesn’t lift up during water flow.

• Anchor the Blanket in the Channel Bottom: Install pins or stakes along the bottom of the channel at regular intervals to ensure the blanket stays in place during water flow.
   

5. Seam and Overlap Treatment

• Check Overlaps: Ensure that the seams where blankets meet are well overlapped (3-6 inches), ensuring no gaps are left where water could erode beneath the blanket.

• Edge Treatment: Stake the edges of the blanket every 6-12 inches to prevent any lifting or damage from water flow.
   

6. Additional Reinforcement (if necessary)

• Add Anchoring in High Flow Areas: If the channel experiences high flow velocities, consider adding additional reinforcements like anchor trenching at the upstream end of the blanket to keep it in place.

• Use Temporary Sandbags (optional): For additional protection, especially in areas with high flow, temporary sandbags may be used to hold the blanket in place until vegetation takes root or the blanket settles.
