Concrete Built for the Pacific Northwest
Seattle’s climate, soils, and code make this region different.
Concrete in Seattle has to handle 37–50 inches of annual rain, glacial-till and expansive clay soils, mild freeze-thaw cycles, and one of the more rigorous permit environments in the country. Construction methods that work in dry climates don’t all translate — we design every project for the conditions actually present on the property.
Drainage is structural design, not an afterthought
The most common cause of premature concrete failure in Seattle isn’t the concrete — it’s the water moving around and under it. A driveway sloped wrong toward the garage, a patio with no positive runoff, a retaining wall without gravel backfill and weep drains — all fail within a few years regardless of slab thickness. Every project starts with grading and drainage planning. Control joints, French drains, channel drains, and proper slope are specified before forms are set.
Soil-appropriate foundations and slabs
Seattle neighborhoods vary dramatically in soil bearing capacity: glacial till that supports spread footings well across much of the city, fill soils that need deeper systems in SoDo and Interbay, and steep hillside lots that may require engineered grade beams or drilled piers. Geotechnical reports drive the engineering, not guesswork. We build to stamped plans and coordinate with SDCI inspectors through each phase of structural work.
Climate-resilient finishes and sealing
Surfaces left unsealed in Seattle’s wet winters scale, stain, and grow moss far faster than in drier climates. We seal new pours with penetrating siloxane or silane, recommend resealing every 2–3 years on high-exposure surfaces, and match finish (broom, exposed aggregate, integral color, stamped) to traffic and sun exposure. See our concrete sealer comparison and moss and mildew removal guide for maintenance context.
Permits and SDOT/SDCI coordination
Right-of-way work (public sidewalks, curb cuts, driveway approaches) needs an SDOT Street Use permit. Structural concrete (foundations, retaining walls over 4 feet) needs an SDCI building permit and engineering. Properties in steep-slope or wetland Environmentally Critical Areas trigger ECA review. We coordinate the applications, inspection holds, and as-built documentation as part of project scope.

How much does a concrete driveway or patio cost in Seattle?
Cost depends on size, access, base prep, reinforcement, and finish. We provide on-site estimates and options for standard broom finishes or decorative upgrades. See our Seattle concrete cost guide for pricing factors.
How long does a driveway or patio project take?
Most residential projects take several days for prep and pour, plus curing time. We'll outline a schedule based on scope, weather, and access.
Do I need a permit for a driveway or patio in Seattle?
Permits can be required when projects impact drainage, utilities, or right-of-way. We confirm requirements and help coordinate inspections. Learn more in our Seattle concrete permits and inspections guide.
How do you prevent cracking and drainage issues?
We evaluate grading, build a compacted base, install reinforcement, cut control joints, and set the right slope to move water away from structures.
When should a driveway or patio be sealed?
Sealing improves stain resistance and protects against moisture. We recommend a maintenance plan based on finish, sun exposure, and traffic after installation or repairs.
