Silt fences
Your ESC Installation specialist contractor
What we use?
Our silt fences are installed using 1.35m steel Y posts, yellow safety caps, high tensile wire (with wire strainers), plastic butterfly clips and woven geotextile fabric. The fabric is made to 100gsm, UV stabilised and meets GD05 porosity and strength requirements.
Whats it for?
The purpose of a silt fence is to slow down your site's runoff flows and allow sediment to settle out of the water. In other terms, silt fences act as temporary barriers that impound (dam) sediment-laden runoff (dirty water), reducing the flow rate so that sediment can settle. It is not designed to filter sediment from the runoff and only has up to 55% efficiency.

Where is it used?
A silt fence is suitable for low-gradient sites or areas with a small contributing catchment. It is designed to intercept sheet flow, not concentrated flow, and should be installed along the ground's contour. Silt fences are particularly useful for minimizing disturbance on earthworks sites, especially near sensitive areas like bushland and wetlands.

Limitations
-
Silt fences are not effective at capturing soil particles finer than 0.02 mm in diameter, such as fine silts and clays. This is due to the short detention time of water behind the fence and the relatively large pore size of the fabric.
-
Silt fences are designed for use with sheet flows and should not be used with concentrated flows.
-
The pores in silt fence fabric can become clogged quickly with fine-textured sediments, rendering the fabric impermeable.
Our Capabilities
Our team specializes in silt fence installations, handling projects of any size—from small-scale urban developments and brownfield sites to extensive land development earthworks sites. Whether it's open fields or dense bush, we've done it all. With a team of two, we can efficiently install up to 250 meters of silt fence per day.
