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

Concrete contractor in Deer Park, WA, for driveways, patios, shop slabs and foundations. Raven Buildings pours residential and light commercial concrete in the City of Deer Park and across north Spokane County, from Clayton and Loon Lake to Chattaroy, built for the colder winters north of Spokane.

Concrete work we do around Deer Park

• Driveways and approaches: new driveways, replacements and the apron where your driveway meets the street
• Patios and walkways: broom-finish and stamped concrete
• Shop and garage slabs: sized for vehicles, lifts and equipment
• Footings and foundations: for shops, pole buildings, steel buildings and additions
• RV pads and parking areas: thicker slabs for heavy loads

Built for Deer Park's climate

The City of Deer Park's building code (Deer Park Municipal Code 15.04.010) sets these local design criteria, and they drive how we pour:

• Frostline depth: 36 inches, compared with the 24-inch minimum used in the Spokane basin, so footings for shops and additions go deeper here
• Weathering: rated severe, which means freeze-thaw damage is the main threat to exterior concrete
• Winter design temperature: -5°F, with an air freezing index of 1,232
• Ground snow load: 56 to 65 lbs per sq ft, which matters for the footings under any building we pour for

For exterior flatwork we use an air-entrained mix, a compacted gravel base, slope away from the house and saw-cut control joints, so the slab moves where we want it to.

Deer Park permits for concrete work

• Driveway approaches: Deer Park requires a development or approach permit before a building permit is issued for new construction with road or drainage improvements, and a construction permit for any work in the city right-of-way (DPMC 12.04.080). We handle the approach paperwork when your job touches the street
• Flat slabs on your lot: outside city limits, Spokane County's permit exemption list includes walks and driveways not more than 30 inches above adjacent grade, not over a basement and not part of an accessible route
• Foundations: footings and slabs for a new shop, garage or home are reviewed as part of that building's permit

What a concrete patio costs

Raven's going rate for a concrete patio, including site prep and the pour, is about $12 to $20 per sq ft for broom finish and $18 to $30 per sq ft for stamped. Where your job lands in that range depends on the size and whether we need a pump to reach the spot.
