Silt Fence Product
Types and Requirements
Question about silt fence types. Are there different kinds of silt fence? Can they be used to control water flowing around my site? I need to control runoff?
Answer:
Great question! I would be happy to answer it for you. The Silt Control Fence, in general, is used as a temporary perimeter erosion prevention & control device around sites where there will be a soil disturbance due to construction and land clearing activities.
The main difference between types of silt fence is the application in which they are made to accommodate. The application will determine the material of the silt fence and the backing used.
In general, we do offer a silt fence that has been rated to meet most state DOT requirements. They are normally manufactured from woven geotextile filter fabric attached to wooden stakes spaced at regular intervals along the site perimeter. The silt fence can be used to control the flow of water, but only if the water is a low level shallow flow, no greater than 5 cfs.
Fabrics used for silt fences should be a pervious sheets of geotextile material such as polypropylene, nylon or polyester. These are chosen based on minimum synthetic fabric requirements. Minimum requirements for silt fence construction (Sources: USEPA, 1992; VDCR, 1995) For example, if a standard strength geotextile is used, it can be reinforced with wire mesh behind the filter fabric.
Additional Erosion Control Options
In addition to the silt fence, we also offer a Staked Silt Barrier. This barrier uses the design and fabrics from our standard turbidity barrier, but is equipped for use with stakes. This creates a strong fabric material to help control the flow of water and direct runoff to certain locations on your site.
These staked silt barriers are used in locations that have a significant water runoff (above 5 cfs) or sheetflow.
