Erosion & Sediment Control
Construction Entrance Installation
Tracked sediment on public roadways is one of the most common and most visible NPDES compliance failures on a construction site — and one of the easiest to prevent. LES installs stabilized construction entrances using graded aggregate over a geotextile fabric base at every vehicle access point, sized to the entrance width and traffic load of the site.
What’s Included
- Geotextile fabric base installation beneath aggregate
- Graded aggregate placement sized to entrance width and traffic load
- Full-width coverage at every vehicle access and egress point
- Periodic top-dressing and regrading as aggregate becomes embedded with site soil
- Coordination with wash rack or tire-wash systems on high-traffic sites
Technical Notes
A properly built construction entrance uses a geotextile separation layer beneath the aggregate to prevent the rock from migrating into the subgrade, with aggregate depth and entrance length sized to the site's traffic and soil conditions — not a token strip of gravel at the gate.
Frequently Asked Questions
Why does a construction entrance need fabric underneath the rock?
Without a geotextile separation layer, the aggregate works its way down into the native soil under traffic load and stops functioning — the rock disappears into the mud instead of stabilizing the surface.
How long does a construction entrance last?
It depends on traffic volume and site soil, but entrances require periodic inspection and top-dressing throughout construction — they are a maintained BMP, not a one-time installation.
