A TerraTex Geotextile silt fence structure acts as a temporary storm water retention pond. The fence serves as a retaining berm and as a porous release structure. TerraTex SC geotextiles are a tough woven fabric designed specifically for silt fences with maximum outdoor life expectancy and minimum risk of damage during installation and service. As with any sediment control method, the required length and specific location of a TerraTex SC silt fence is dependent on the size and slope of the site and the expected peak rainfall

Sediment run-off from construction sites is more than an environmental hazard; it is also a hazard to the profitability of the contractor and owner. Uncontrolled silt flows during heavy or prolonged rainfall can choke vegetation in nearby waterways, cause serious damage to adjacent property, create slick road surfaces and clog storm water drains. TerraTex SC fabric was designed to prevent this environmental damage and eliminate costly clean up operations. Low cost, east-to-install silt fences using TerraTex SC offer an effective and economical solution to controlling sediment run-off.

A TerraTex Geotextile silt fence controls sediment runoff by:
slowing the velocity of the run-off stream and causing the separation of suspended soil and water (precipitation) behind the structure.
Filtering the suspended soil from the water as the run-off stream is discharged through the fabric
reducing the potential of downstream erosion by slowly releasing the run-off stream

Construction
1. Dig a trench for fabric toe-in where the fence is to be installed (6 inches deep by 6 inches wide is adequate). If the alternate toe-in method shown above is used, ensure a supply of soil is available.
2. Set posts securely in the ground within a few inches of the trench and attach support material to posts. (The type and spacing of the materials should comply with project or regulatory specifications.) A fence constructed from light weight materials is more than adequate in areas where run-off is low in velocity and volume. High velocity or volume run-off areas will require a more substantial structure (i.e., metal posts, close pole spacing, and hog wire support).
3. Attach fabric to fence structure allowing 6 inches to lay in the toe-in trench. Hog nose rings, nails and wire have all been effectively used in attaching fabric to fence.
4. Fill toe-in trench with soil and compact. If alternate method is used, lay 6 inches of fabric flat on the ground and cover with a minimum of 4 inches of soil and compact. Soil compaction is critical to eliminate channeling under the fence.

Location
1. The fence should be located to intercept all silt/water run-off from the site.
2. Sufficient extension of each fence section should be installed (preferably uphill) to ensure run-off will not go around the ends.
3. A series of silt fences may be required if there is a possibility that the volume of runoff could fill the retention area and flow over the fence.
