CONCRETE IN SEATTLE
Built for the rain, not just the summer
Seattle concrete surfaces must withstand months of wet weather, slow-draining soil, and the challenges of steep or uneven properties. Many cracked, sunken, or waterlogged slabs develop problems because of inadequate drainage, poor soil compaction, or insufficient base preparation.
Our team focuses on identifying these underlying issues before recommending practical improvements. We also provide concrete repair services in Central Washington, with careful site evaluation, proper grading, and suitable materials to help homeowners and businesses maintain stronger, more stable surfaces.
Drainage first
Every slab gets a planned slope so rain runs toward the yard or a drain, never toward your foundation.
A base that holds
Soft or wet soil comes out and compacted gravel goes in, so the slab doesn't settle after a few winters.
Finishes that grip
Broom finishes and anti-slip sealers keep driveways, steps and patios safer when they're wet.
Steep lots handled
Hillside driveways and sloped yards get the forms, steps and reinforcement they need.
COMMON SEATTLE PROBLEMS
Concrete problems we fix in Seattle
Rain, shade, big trees and older neighborhoods are hard on concrete. These are the repairs we’re called for most.
Cracked driveways
Older driveways crack when the base settles or tree roots push from below.
Our fix: We tear out the damaged sections, rebuild the base and pour with control joints.
Sunken or tilted slabs
Wet soil washes out under patios and walkways until they sink or tip.
Our fix: We remove the slab, add compacted gravel and repour it level.
Water pooling by the house
Flat or back-sloped slabs send rain toward your foundation.
Our fix: New slabs get a planned slope so water drains away from the house.
Slick, mossy surfaces
Shade and constant rain let moss grow on smooth concrete.
Our fix: We clean the surface and seal it with an anti-slip additive, or pour a broom finish.
Root-lifted walkways
Yard and street trees lift panels and leave trip edges.
Our fix: We replace the lifted sections and set new joints to control future cracking.
Crumbling steps
Old steps flake and lose their edges after years of wet winters.
Our fix: We repair what is sound and rebuild the rest with even, safe steps.

SEATTLE FAQ
Questions we hear from Seattle customers
Yes. We’re based in Arlington and take residential and commercial concrete work throughout Seattle and nearby cities like Shoreline, Bellevue, Kirkland and Renton.
We schedule pours around the forecast and avoid placing concrete in steady rain. If a shower comes after finishing, we cover the fresh slab to protect the surface while it sets.
It depends on the scope. Work on your own lot often needs no permit, but a new curb cut, driveway approach or sidewalk panel in the public right-of-way needs a permit from the Seattle Department of Transportation. We’ll tell you what your project needs before we quote it.
You can usually walk on it after a day or two and drive a car on it after about a week. Concrete keeps gaining strength for around four weeks, so heavy trucks should wait longer.
A sealed stamped patio can get slick in the rain, so we mix an anti-slip additive into the sealer on walkways, steps and pool decks.
