Concrete Overlays in Auburn, WA

Concrete overlays in Auburn: what to know

The first question here is whether the slab has stopped moving. Much of Auburn’s flat ground is river alluvium, which King County’s review of a nearby valley site called prone to settling under load. A driveway that dropped at one corner will carry that drop through a new surface. A slab that is flat, with cracks that have stopped growing, is a fair candidate.

The public side is different. Auburn requires sidewalks on public streets to be concrete and at least four feet wide, and the code lets a sidewalk that falls short of its standards be removed and replaced at the abutting owner’s cost. A surface coat does not change that. Prep slurry and wash water need care too, because the city’s storm drains run to the nearest creek or river.

Permits and rules in Auburn

A resurfaced private slab keeps its footprint and grade, which generally keeps it outside building permit review. The apron and sidewalk are in the public way, and construction or excavation there takes a construction permit from the city engineer under Title 12 of the city code. Auburn’s stormwater program treats dumping into a street drain as dumping into the waterway. We confirm with the Permit Center how the city treats resurfacing at the apron before we quote.

Rules change and vary by parcel, so we confirm the current requirements with the city before we start.

How we approach it

Sound the slab for settlement before choosing an overlay on valley ground
Stop at the property line unless the city approves work on the apron
Contain slurry and wash water so none reaches a street drain
Choose a gripping texture for shaded or sloped driveways

Questions from Auburn homeowners

Will an overlay fix the cracked sidewalk in front of my Auburn house?

No. The code requires public-street sidewalks to be concrete and at least four feet wide, and a sidewalk that falls short can be ordered removed and replaced at the abutting owner’s cost. Repair in the public way needs a city permit, so we ask before touching one.

Can my driveway on the Auburn valley floor be resurfaced if one corner has sunk?

Not yet. Valley alluvium can settle, and in a strong earthquake it can liquefy, so a slab that dropped carries the drop into a new surface. We replace the sunken section and fix the base first, then resurface the rest if it is sound.

Where does overlay wash water go in Auburn?

Not into the street. Auburn’s storm drains run to the nearest creek or river, and the city treats dumping in a drain as dumping in the waterway. We contain slurry and rinse water on the job.
