Concrete Contractor in Colville, WA: Driveways, Patios, Shop Slabs & Foundations

Concrete contractor in Colville, WA, pouring driveways, patios, shop slabs and foundations built for Stevens County winters. Raven Buildings brings the same crew that pours our steel building foundations to Colville and the Colville Valley, with air-entrained mixes, compacted base and footings set below the local frost line. Inside city limits we build to the City of Colville's standards; outside them, to Stevens County's.

Concrete work we do around Colville

• Driveways and approaches: new driveways, replacements and widening, with control joints laid out before the pour
• Patios and walkways: broom-finish and stamped patios, steps and sidewalks
• Shop and garage slabs: floors for metal buildings, pole barns and detached garages, thickened where lifts or heavy equipment will sit
• Foundations and footings: for shops, garages, additions and pre-engineered metal buildings
• RV pads and equipment pads: parking for motorhomes, trailers, tractors and farm or logging equipment

Built for Colville's climate

The City of Colville's published design criteria spell out what concrete is up against here:

• Frost depth: 30 inches, measured from finished grade to the bottom of the footing. The Stevens County building ordinance sets the same 30-inch minimum for footings outside city limits
• Weathering: rated severe
• Winter design temperature: -5 degrees F
• Roof snow load: 40 psf, which matters for any shop or garage that sits on the slab we pour

In a severe weathering region, the International Residential Code (Table R402.2) calls for at least 3,500 psi concrete with 5 to 7% entrained air for garage floors, porches and carport slabs. For driveways and flatwork that see deicers, the residential concrete code ACI 332-20 calls for 4,500 psi with a maximum water-to-cement ratio of 0.45. We order mixes to match and we don't add water on site.

Driveways in Colville: what to know

• Thickness: 4 inches is the minimum for cars and pickups, and 5 to 6 inches is the better choice for delivery trucks, trailers, RVs or a loaded pickup. Our driveway thickness guide covers base, joints and rebar
• Work in the street right-of-way: per Colville Municipal Code 12.20.130, anyone building curbs, sidewalks or paving in a public right-of-way or public easement needs a permit from Colville Public Works (1044 N. Lincoln Street, 509-684-5096)
• Commercial driveways: Colville Municipal Code 12.24 limits commercial driveways to 12 to 30 feet wide, keeps them at least 5 feet from an intersecting street's property line and crosswalks, and caps total driveway width at 40% of the property's street frontage
• Outside city limits: county roads have their own approach rules, so we check with Stevens County before we form anything

Pouring before winter, or during it

Concrete can't go on frozen ground and has to be protected from freezing while it cures. Late-fall and winter pours in Colville need blankets, heated enclosures or accelerators, and sometimes the right call is to wait for spring. Our winter concrete guide explains what changes in cold weather, and our sealing guide covers deicers in a new slab's first winter.

What a concrete patio costs

Raven's current pricing for a concrete patio, including site prep and the pour:

• Broom finish: about $12 to $20 per sq ft
• Stamped: about $18 to $30 per sq ft
• What moves the price: the size of the patio and whether a pump truck is needed to reach it

Driveways, shop slabs, RV pads and foundations are priced per project after a site visit, since base work, thickness, tear-out and access change the cost. Weighing your options? See our stamped concrete vs. pavers guide.

Slab and building from one contractor

If you're putting up a shop, we can pour the footings and floor and erect the building too. See our page for metal buildings in Colville and our shop slab thickness guide.
