Silt Fence Installation — Dallas–Fort Worth
Silt fence is the workhorse of erosion control: the perimeter of fabric that keeps disturbed soil on your site instead of in the street, the storm drain, or the neighbor's lot. Done right, it disappears into the background. Done wrong, it is the first thing a city inspector photographs and the reason a project draws a corrective action. Terradyne installs and maintains silt fence across the Dallas–Fort Worth metroplex to the standard the code actually requires, not the shortcut a tired crew reaches for at the end of a long day.
What does a code-compliant silt fence installation require in Dallas–Fort Worth?
The iSWM standard silt fence detail specifies a minimum fence height of 24 inches above existing ground. Terradyne installs to that regional standard and taller where flows demand, with wire-backed fabric, steel posts, and a trenched fabric toe, so the perimeter actually holds sediment and passes inspection the first time.
When is silt fence required?
Silt fence is one of the structural sediment controls recognized under the TPDES Construction General Permit TXR150000. On nearly every dirt-moving job in North Texas, a perimeter of silt fence is the first control installed and the last one removed. It is what keeps disturbed soil from leaving your site and becoming someone else's problem downstream, and it is what a reviewer looks for before almost anything else. Install it late and the compliance record is already behind before the first load of dirt moves.
How silt fence is built to spec
The details are what separate a fence that works from one that fails at the first storm. The iSWM silt fence detail specifies steel fence posts at a maximum 6-foot spacing with a minimum 1-foot embedment. The iSWM silt fence detail calls for wire-mesh backing support of 4x4-W1.4xW1.4 minimum. The iSWM detail buries the silt fence fabric in a compacted toe trench, with a 12-inch fabric toe-in. Terradyne trenches the toe, backs the fabric with wire, and sets posts deep enough that the fence stays standing when it is loaded with mud, instead of folding flat and letting the hillside wash straight through. Fabric merely draped on the ground, and posts spaced too far apart, are the two failures our inspectors write up most often.
Keeping silt fence working
Installation is only half the job; a silt fence that fills with sediment and is never cleaned is just a decoration. Under TXR150000, trapped sediment must be removed from perimeter controls such as silt fence before it reaches 50% of the above-ground height. Terradyne's crews watch that line and call for cleanout before it is buried, because a fence loaded to capacity stops filtering and starts steering water around its ends. Routine maintenance is far cheaper than the re-work and the violation that follow a blowout during the next storm.
Silt fence on TxDOT projects
Roadway work plays by a heavier rulebook, and the wrong fence on a state job invites a rejection you cannot afford mid-schedule. On TxDOT projects, silt fence is specified as a Temporary Sediment Control Fence: a net-reinforced fence using woven geotextile fabric. TxDOT places temporary sediment-control fence near the downstream perimeter of a disturbed area to intercept sediment from sheet flow. TxDOT does not allow logos visible to the traveling public on temporary sediment control fence. On state-highway work, Terradyne installs to that heavier standard; see our TxDOT Heavy-Duty Silt Fence page for the specifics.
Terradyne's silt fence service across Dallas–Fort Worth
Terradyne has installed and maintained erosion control across North Texas since 1988, and silt fence is the control we set more of than any other. Terradyne installs wire-backed silt fence with heavy-duty steel posts as its standard perimeter sediment control. Terradyne offers logo-printed (branded) silt fence with customer branding on the fence fabric. On private jobs, branded fence turns a required control into a moving billboard for your project: ask about our Branded Silt Fence (Logo-Printed) option. Whether it is a single pad site or a phased development, the crew that installs your fence is the crew that comes back to maintain it, so nothing falls through the cracks between visits.
Match the control to the flow
For runoff that concentrates rather than sheet-flows, pair silt fence with rock check dams or inlet protection; confirm the right control for each drainage path. City and TxDOT silt-fence details vary; confirm the governing spec for your jurisdiction before installing. Explore our Storm Drain Inlet Protection and Rock Filter Dams for the spots silt fence cannot handle, and the full Erosion Control division for everything else your site needs to stay compliant. Getting that mix right from the start is what keeps a project quietly in the clear instead of fighting the same washout storm after storm.
Frequently Asked Questions
What is silt fence?
Silt fence is a temporary sediment barrier: a run of geotextile fabric on posts, set along the downhill edge of disturbed ground to filter muddy runoff before it leaves the site. It is the most common perimeter control on construction jobs.
How tall does silt fence have to be?
Height is set by the governing detail and the job conditions. On typical commercial sites we install to the regional standard and go taller where slopes or flows are heavy, because a short fence overtops and fails.
Can I get silt fence printed with my company logo?
Yes. Terradyne offers logo-printed silt fence with your branding on the fabric for private projects. On public-road work, agency specifications may bar public-facing logos, so we keep branded fence to jobs where it is allowed.
Does silt fence work everywhere on a site?
No. Silt fence is built for sheet flow: thin, spread-out runoff. Where water concentrates into a channel or heads for an inlet, it needs check dams or inlet protection instead, or it will undercut and blow out.
