Inlet Protection in Wilmington, NC

Stone, wire mesh, and filter protection around storm drain inlets that keeps construction sediment out of the storm system and complaints off your desk.

Guarding the Storm System

What Inlet Protection Is and Why Inspectors Look for It First

Storm drains are express lanes. Whatever washes into an unprotected curb inlet or yard drain does not get filtered along the way; it rides the pipe straight to a ditch, a stormwater pond, or one of our creeks. That is why sediment entering an inlet is one of the fastest ways to earn a violation on a Wilmington-area job site.

The right device depends on the inlet and the water it sees: curb inlets on live streets need filtering that will not flood the road, drop inlets in graded pads can take a stone and wire mesh ring, and low-flow areas may only need a staked wattle or silt sack. We install them all, match the device to the situation, service them through the life of your project, and remove everything cleanly once the site is stabilized.

In Short

Inlet protection is a temporary barrier or filter installed at storm drain inlets near disturbed soil, built from stone and wire mesh, filter fabric, silt sacks, or wattles depending on the inlet and flow. It traps sediment before runoff enters the storm system, where it would otherwise flow straight to ditches, creeks, and ponds.

The Right Device for Each Drain

Inlet Protection Services We Offer

Different inlets, different flows, different devices. Here is what we install and maintain on sites across the Cape Fear region.

Stone and Wire Mesh Barriers for Drop Inlets

The workhorse for drop and yard inlets on active sites: a ring of hardware wire wrapped with stone that lets water pass while briefly ponding it, giving sediment time to settle out before the flow enters the grate. It stands up to equipment traffic nearby and heavy summer storms better than fabric-only solutions.

We build these to hold their shape, with the wire properly formed and anchored and stone at the right size. A slumped ring with gaps at the base is just an expensive decoration around a drain that is eating your site's sediment.

  • Wire-formed stone rings for drop inlets
  • Ponds water briefly so sediment settles
  • Stands up to storms and site traffic
  • Built to spec, anchored, gap-free
  • Serviced and refreshed as sediment loads up

Silt Sacks and Under-Grate Inserts

For curb inlets and paved areas where an above-ground barrier is not practical, we install silt sacks and basin inserts that hang beneath the grate and catch sediment inside the structure itself. Traffic passes right over them, and the street keeps draining.

The catch with sacks is that they fill up, and a full sack either bypasses or backs water into the street. We monitor and empty them on a schedule that matches your site's activity, which is the difference between a functioning device and a paperwork liability.

  • Under-grate sacks for curb and street inlets
  • No obstruction to traffic or paving
  • Keeps paved-phase sediment out of the system
  • Scheduled cleanout and replacement
  • Clean removal at project close-out

Wattles, Barriers, and Whole-Site Combinations

For low-flow situations and finished-but-not-yet-vegetated areas, staked wattles around an inlet slow water and filter sediment without major installation. They also work as check structures in swales feeding an inlet, knocking sediment out of the flow before it ever arrives at the drain.

Most sites need a combination: fence at the perimeter, wattles in the swales, stone rings at the pads, sacks in the curbs. We look at the whole path water takes across your site and protect it as a system, because sediment control devices work together or they barely work at all.

  • Staked wattles for low-flow inlets
  • Check wattles in swales and ditch lines
  • Whole-site device planning, not piecemeal
  • Coordinates with silt fence and outfalls
  • One crew for your full sediment package

Straight Answers

Inlet Protection Questions From Local Job Sites

If your project falls under an approved erosion and sediment control plan, which any disturbance of an acre or more does, inlet protection will be among the required measures wherever runoff from disturbed areas can reach a storm drain. Even on smaller projects, letting sediment enter the public storm system invites complaints and enforcement, so protecting nearby inlets is cheap insurance.

There is no single best, only the best match for each inlet. Stone and wire mesh rings suit drop inlets on active dirt sites, silt sacks suit curb inlets on paved streets, and wattles suit low-flow situations. Flow volume, traffic, and flooding risk all factor in, and we will spec the right mix for your site rather than one device everywhere.

Check devices after every significant rain and on a regular schedule between storms. Sediment-loaded devices stop filtering and can cause bypassing or ponding where you do not want it. We offer maintenance on everything we install so devices keep working and your inspection log stays clean.

Yes. Curb inlets on active roads call for under-grate silt sacks or low-profile filter devices that do not block traffic or flood the lane. This is one of the more common requests we get from builders working infill lots around Wilmington, where the storm system is right at the curb.

The whole package. Silt fence perimeters, inlet protection, check wattles, construction entrances, outfall armor, and the seeding that ultimately stabilizes the site. Having one local crew responsible for all of it means devices get installed as a coordinated system and maintained by people who see the whole picture.
