Sediment Fence (Silt Fence): The Complete Jobsite Guide to Erosion Control & Stormwater Compliance

Sediment Fence is a proven perimeter BMP that keeps soils on-site—and out of storm sewers, streams, and wetlands. Crafted from durable woven polypropylene yarns and shipped with eleven 36" oak stakes for stable installation, it’s built to stop sediment-laden runoff at the jobsite boundary and help you pass inspections.

What Is a Sediment Fence?

Plain-English: A sediment fence (also called a silt fence) is a temporary, ground-trenched fabric barrier that slows water at the site boundary so soil drops out before reaching inlets and waterways.

Technical: A low-permeability woven polypropylene geotextile is trenched and backfilled along the upslope edge and attached to a line of 36" oak stakes on the downslope side. The trench resists undercutting, the fabric impounds and filters sheet flow, and the stake line provides structural resistance to blowouts.

Why it matters: Most construction stormwater permits require perimeter BMPs. Properly installed sediment fence is a low-cost, high-impact control that reduces cleanup and violations.

Benefits & Best-Use Scenarios

  • Effective filtration: Traps fine sediments at the boundary to protect streams and storm sewers.
  • Rugged build: Woven PP fabric + eleven 36" oak stakes per bundle for stable installation.
  • Fast deployment: Simple trench–stake–attach–backfill sequence speeds setup and inspection readiness.
  • Compliance support: Helps satisfy SWPPP intent and typical municipal BMP requirements.
  • Cost control: Reduces regrading, street sweeping, and downstream restoration.
Use it: Along down-slope perimeters of pads and lots, near swales/ditches (with inlet protection at structures), and as a buffer parallel to wetlands and creeks.
Avoid: Spanning concentrated channels without added BMPs; leaving gaps at panel joints; installing out of level (not on contour).

Placement Tips that Boost Performance

Long run of sediment fence installed on contour across a graded slope for erosion control
Install on contour and return ends upslope to prevent end-around bypass.
  • Follow the contour: Keep the top line level so flow spreads out and slows uniformly.
  • Return the ends: Curve fence ends upslope into a shallow “J” to block bypass.
  • Tie sections tightly: Overlap ≥12" and share a stake; no daylight at seams.
  • Mind spacing: Start at 6–8 ft stake spacing; tighten in high-flow or soft soils.
  • Maintain: Remove sediment when it reaches ~50% of fabric height; repair tears promptly.

How to Install Sediment Fence (Step-by-Step)

  1. Lay out on contour: Mark the down-slope perimeter; avoid channels where flow concentrates.
  2. Trench: Excavate ≈6" deep × 6" wide on the upslope side to prevent undercutting.
  3. Set stakes: Drive the 36" oak stakes on the downslope side at 6–8 ft spacing (closer in high-flow zones).
  4. Attach fabric: Fasten woven PP to stakes; seat ≥6" of fabric in the trench.
  5. Backfill & compact: Backfill the trench on the upslope side and tamp to seal against seepage.
  6. Join panels: Overlap ends by ≥12" around a shared stake; tie off tightly.
  7. Inspect after storms: Remove captured sediment at ~50% height; repair, re-tension, or re-anchor as needed.

Case Study: Commercial Pad — From Warnings to Clean Inspections

Project: 5-acre retail pad on gentle slopes draining toward a municipal inlet and a small stream.

Challenge: Two early spring storms caused sediment tracking and turbidity spikes at a curb inlet, triggering inspector warnings.

Solution: Crew installed Mainline Materials Sediment Fence on contour with eleven 36" oak stakes per bundle. Ends were returned upslope, overlaps shared a stake, and curb-box inlet protection was added.

  • Results: Subsequent 1"+ storms produced visible capture behind the fence with no off-site discharge.
  • Maintenance: Sediment removed at ~50% fabric height; minor repairs completed same day.
  • Outcome: Passed re-inspection; estimated 25–35% reduction in regrading and street sweeping.

Takeaway: Strategic placement, proper trenching, and tight seams transformed a problem area into a compliant, low-maintenance perimeter.

FAQs

Can I run sediment fence across concentrated flow?
Avoid spanning active channels without additional BMPs (e.g., check dams). Sediment fence works best on contour to intercept sheet flow.
How long should a sediment fence remain in place?
It’s a temporary BMP for the construction phase. Keep it until disturbed areas are stabilized (vegetation or hardscape), while maintaining after every storm.
How do I prevent water from going around the ends?
Return ends upslope into a shallow “J” shape and tie into grade; overlap panels around a shared stake to remove gaps.
