Silt Fencing: Cost Effective and Good for the Environment

Because of its effectiveness in trapping sediments that could otherwise enter and contaminate nearby water sources, silt fencing is an essential part of erosion control on construction sites.  Wire-backed silt fences are cost-effective and require virtually no maintenance. They are known for their durability, resistance to wind damage, and the ability to handle large amounts are water and silt.
    Proper installation is crucial in order for the fence to perform it's intended job optimally. Use the following guidelines for fence installation:

• Establish a position for the fence. The location should be on the downhill edge of bare soil areas.
• Dig a trench along the line that is 6" deep and 6" wide.
• Install fence stakes by hammering them into the ground on the opposite side of the fence from where the runoff is originating. Stakes should be at least 12" into the ground and approximately 6' apart.
• Unroll fabric and attach to stakes with staples or purchase pre-pocketed fence in which stakes can be inserted directly into the material.
• Fill trench with soil and pack down using a compacting machine or iron hand tamper.

Some government jurisdictions in the U.S. recommend or require the use of a reinforced or  "super" silt fence which is reinforced by wire mesh or a chain link fence. The metal backing serves to both enhance the fence's ability to resist the weight of soil/water, while also helping to prevent potential damage to the fence from construction vehicles.
