Wholesale sealcoat for Eastern Washington.

Material west into the Spokane corridor and the Columbia Basin — delivered on volume, or loaded at the yard 35 miles from downtown Spokane.

Washington, outlined, with the yard at Rathdrum just over the Idaho line and the roads west: I-90 through Spokane to Moses Lake and on to Wenatchee, US-395 north to Colville, US-2 to Newport, US-195 south to Pullman.Rathdrum

Eastern Washington is a supply region. The Rathdrum yard sits about 35 miles from downtown Spokane, which makes it a shorter trip for a Spokane Valley contractor than most of his own jobs, and the I-90 and US-2 corridors put the rest of the region inside a delivery run once the order is a volume order.

If you order it as slurry seal, that is what this is — asphalt emulsion, sand and bentonite clay. “Sealcoat” is the Idaho word for the same tank.

Contractors working the Basin are usually fighting oxidation rather than water, and that changes what a surface needs — a thirsty, sun-burned mat drinks the first coat and the second one is what actually seals it. Worth saying out loud when you call, because it changes the volume you should be ordering.

What the pavement is up against here.

Two different pavement problems share one region. Spokane and the Palouse get the same freeze-thaw punishment as North Idaho and fail by water. Out in the Columbia Basin the winters are milder and the summers are brutally clear, so surfaces fail by ultraviolet instead — binder driven off from the top, the mat going gray and raveling under traffic long before anything cracks open.

The season.

Around Spokane the window is the North Idaho one — typically mid-April to the end of September. The Basin is the dry side of the state, and loses fewer of those days to rain.

Super Seal 100 goes down at 60°F and rising — whatever the calendar says, that is the rule that decides a working day.

Questions from Eastern Washington.

How far is the yard from Spokane?

About 35 miles from downtown, off SR-53 in Rathdrum, Idaho — a shorter trip for a Spokane Valley contractor than most of his own jobs. Will-call is at the yard.

Do you deliver sealcoat into the Columbia Basin?

Yes, on volume. Delivered loads start at 3,500 gallons and go out I-90 and US-2 — Ritzville, Moses Lake, Ephrata, Quincy, Wenatchee.

Is this slurry seal or sealcoat?

Both. The name changes at the state line; the tank does not. It is Super Seal 100 — asphalt emulsion, sand and bentonite clay, mixed at our yard.

Does a Basin lot take more material?

Often. A sun-burned, oxidized mat drinks the first coat, and coverage runs 35 to 120 square feet per gallon depending on the surface. Say what the surface is doing when you call, because it changes the volume you order.

When does the season open on this side?

The rule is 60°F and rising. Around Spokane that is the North Idaho window, typically mid-April to the end of September; the Basin is drier and loses fewer of those days to rain.

All the questions, answered by the plant →

Before you call.

Sealer is priced on volume and distance. Bring these and the quote is a conversation, not a callback.

  1. Square footage, and how many coats.

    Sets the volume. A rough measurement beats a guess by a mile.

  2. What the surface is doing now.

    Raveling, oxidised, or just dull — it changes what the surface will take.

  3. The tank you are putting it in.

    It is sold in bulk and it lives in an agitated tank. Delivered loads start at 3,500 gallons, so the tank decides pickup versus delivery.

  4. The week you need it.

    It goes down at 60°F and rising, which around here is mid-April to the end of September. The season is short.
