Silt Fence Installation
Silt fence installation puts a trenched-in sediment barrier along the downslope edge of disturbed ground so runoff drops its soil before leaving your construction site.
Silt Fence for planned site work
Silt fence is the workhorse of construction-site sediment control: a geotextile barrier installed along the downslope edge of disturbed ground that ponded runoff filters through, dropping its sediment on your site instead of in the ditch, wetland, or lake below. JL Landworx installs silt fence on construction sites across Central Minnesota and the greater Twin Cities.
Installed wrong, silt fence is decoration. A fence that isn't trenched in lets runoff flow underneath; one that isn't supported blows over in the first storm; one that follows the wrong line concentrates water until it overtops. We trench, post, and backfill silt fence the way it is supposed to be done, on the contour, so it actually holds when it rains.
Silt fence is usually one part of a broader erosion control plan — paired with inlet protection at storm drains and stabilization of bare ground — and on our projects it goes in as part of the excavation, grading, or clearing work rather than as a separate mobilization.
Problems silt fence solves
- A construction project needs sediment control in place before dirt work begins
- Runoff from a disturbed site is carrying soil toward ditches, wetlands, or neighboring property
- An existing silt fence has failed — overtopped, blown over, or undermined
- A cleared or graded site is sitting bare and the first hard rain will wash it
- A project inspector or reviewer has flagged missing or inadequate silt fence
What we do
- Silt fence installation along site perimeters and downslope boundaries
- Proper trenching-in of the fabric toe so runoff can't flow underneath
- Fence layout on the contour to pond water rather than concentrate it
- Silt fence around stockpiles, wetlands, and other sensitive areas
- Repair and replacement of damaged or failed sections during the project
- Removal of silt fence once the site is stabilized
- Sediment control integrated with excavation, grading, and clearing scopes
Our silt fence process
Site walk and layout
We walk the site to see where runoff will leave disturbed ground and lay out the fence line on the contour, protecting ditches, wetlands, and property lines downslope.
Trenching and posting
Posts are driven along the line and a trench is cut so the bottom of the fabric can be buried — the step that keeps water from short-circuiting under the fence.
Fabric installation and backfill
The fabric is fastened to the posts, the toe is set in the trench, and the trench is backfilled and compacted so the fence seals to the ground.
Maintenance through the project
The fence is checked after storms, accumulated sediment is addressed, and damaged sections are repaired so it keeps working until the site is stable.
Common projects
- Home and cabin construction sites
- Commercial construction and site development
- Land clearing and grading projects
- Driveway and road construction
- Projects near wetlands, lakes, and drainage ways
- Utility and roadwork corridors
Planning your project
What affects cost
- Linear footage of fence required
- Site conditions — slopes, rocky or hard ground, and access along the fence line
- Whether fence is installed standalone or as part of larger dirt work
- Project duration and how much maintenance the fence will need
- Whether failed existing fence must be removed and replaced
What affects timing
- How much fence the site needs and how the ground digs
- Weather — fence should be in place before forecast heavy rain
- The construction schedule, since fence goes in before or as ground is disturbed
- Growing conditions, which determine when the site is stable enough for removal
Good to know
- Many projects are required to have sediment controls like silt fence in place before ground is disturbed — confirm what applies to your project early, since it affects the schedule.
- Silt fence is a sediment control, not an erosion cure — the real fix is stabilizing the bare ground upslope with seed, mulch, or surfacing.
- Fence location matters more than fence quantity: it belongs on the contour where runoff actually leaves the site, not just along the property line.
- Plan for maintenance. Silt fence that is never inspected fails quietly, and a failed fence is the same as no fence.

FAQ
Silt Fence questions
Is my project required to have silt fence?
Many projects are required to have sediment controls in place when soil is disturbed, especially larger sites and work near waters or storm systems. What applies to your project depends on its size, location, and the authorities involved — confirm your specific requirements, and we will install to them.
Why does silt fence have to be trenched in?
Because water flows downhill and takes the path of least resistance. If the bottom of the fabric sits on the surface, runoff flows straight under it and the fence catches nothing. Burying the toe in a backfilled trench seals the fence to the ground so water has to pond and filter through the fabric.
How long does silt fence last?
The materials hold up for a season or more, but the fence's useful life is really about maintenance — fabric that is buried in sediment, torn, or blown over stops working. It stays in place, maintained, until the ground above it is stabilized, and then it comes out.
Can silt fence handle a heavy rain by itself?
Within limits. Silt fence is designed to pond runoff and let it filter through slowly — not to stop concentrated flow. Sites with big drainage areas need the fence laid out so water spreads along it, and often need other measures alongside it. Layout and stabilization matter as much as the fence itself.
Do you install silt fence by itself or only with other work?
Both. Most of our silt fence goes in alongside excavation, grading, or clearing on the same site, but we also install it as a standalone scope when a project just needs sediment control brought up to standard.
