Magnesium Chloride Dust Suppression That Keeps the Dust Down All Season
If you live on a gravel road or have a long gravel driveway anywhere in Spokane County, you already know the summer routine: a rooster tail of dust behind every vehicle, a fine brown film on the house and the cars, and washboard ruts that get worse every week. Spokane Dust puts an end to it. We’re a locally owned dust control company specializing in magnesium chloride application for gravel roads, private lanes, and driveways throughout Spokane and the surrounding unincorporated county.
From the gravel roads of Moran Prairie and Glenrose on the South Hill, to the orchards and acreages around Green Bluff, Colbert, and Mead to the north, our region’s dry Inland Northwest summers turn untreated gravel into airborne dust by June. We treat the surface once, and it stays knocked down through the dusty months — protecting your air quality, your vehicles, and your road itself.
Locally owned and operated. We live and work in the Spokane region. We know the roads, the seasons, and the kind of basalt-and-clay gravel that’s common around here.
Licensed, insured, and bonded. Dust abatement is a chemical application on (sometimes) public and shared roads. We carry the proper licensing and insurance so you’re covered.
Magnesium chloride that actually lasts. Magnesium chloride is hygroscopic — it pulls moisture out of the air and holds it in the road surface, binding the fine particles together so they stay put. A single properly-timed application keeps the dust down through the dry season, unlike a water truck that’s dry again in an hour.
Free, no-pressure measurement and quote. We measure your road or driveway, confirm the footage, and give you an honest price before any work begins.
We work with the county. Spokane County maintains an approved dust-abatement contractors list for residents who want treatment on county-maintained gravel roads. We’ll walk you through how that process works.
Whether it’s a quarter-mile private road or a long shared lane, we apply magnesium chloride at the right rate to lock down the surface and keep your road drivable and dust-free.
Long rural driveway kicking up dust every time you come home? One treatment keeps your vehicles clean, your windows closeable, and your gravel where it belongs.
Many Spokane County acreages share a private road. We make it easy for neighbors to split a single application — one measurement, one fair price, one scheduled visit.
We set up recurring seasonal programs for subdivisions and homeowner associations so the whole community’s roads get treated on a predictable schedule.
For residents along county-maintained gravel roads, we provide the magnesium chloride application that keeps your stretch dust-free, coordinated with county requirements.
Earthwork, lots, and haul roads generate regulated dust. We help Spokane contractors stay compliant and keep neighbors happy with dependable suppression.
Riding arenas, feedlots, and ranch roads all benefit from magnesium chloride dust control — healthier air for animals and people, less dust drifting onto neighboring property.
Magnesium chloride isn’t a temporary fix like spraying water. As a deliquescent salt, it continuously draws humidity from the air down into the top layer of your gravel, keeping it slightly damp and binding the fine dust particles into a firm, stable crust. The result:
We treat gravel roads and driveways throughout Spokane and the surrounding county, including Moran Prairie, Glenrose, Five Mile Prairie, Mead, Colbert, Chattaroy, Green Bluff, Fairwood, and the rural acreages in between. We also serve the nearby West Plains communities of Cheney, Airway Heights, and Medical Lake, and north county around Deer Park.
Late spring through early summer, once the road has been graded and the surface is workable but the dry season is setting in. Treating before the worst of the summer dust gives you the longest-lasting results.
A properly-timed magnesium chloride application typically controls dust for the full dry season. Heavy traffic, fresh grading, or an unusually wet-then-dry cycle can affect longevity, and many customers re-treat annually.
Yes — this is one of our most common Spokane County jobs. We measure the shared road once and give neighbors a single price to split however they like.
Magnesium chloride is a widely used, well-established dust control product. We apply it at calibrated rates designed to control dust effectively while being mindful of roadside vegetation and runoff.

"Our long gravel driveway off Moran Prairie used to coat every car in a brown haze all summer. One treatment and the dust was gone for the whole dry season. Worth every penny."
"We share a private lane with four other families and finally went in together on dust control. The crew measured it, gave us one fair price to split, and knocked it out in an afternoon."
"I run a small contracting yard and needed to keep the dust down for the neighbors. Professional, on time, and the magnesium chloride held up far longer than the water truck ever did."

Late spring through early summer is ideal — after the surface has been graded and before the dry season peaks. A well-timed magnesium chloride application keeps the dust down for the full dry season.
Magnesium chloride is hygroscopic, meaning it pulls moisture from the air into your gravel to keep the surface bound and damp. Unlike water, which dries out within an hour, a single treatment controls dust all season while reducing gravel loss, washboarding, and maintenance.
