Concrete Overlays in Snohomish, WA

Concrete overlays in Snohomish: what to know

An overlay sits on top of the slab, so it cannot correct movement underneath. We probe the edges and the garage approach for soft ground, cut out failed concrete, and rebuild the base before any product is mixed.

The city’s permit list is where the paperwork changes. SMC 12.20.130 covers installing, removing, altering, repairing, replacing, or constructing a driveway, sidewalk, curb, or gutter, and it says the work cannot begin until a Public Works permit is issued. The state residential exemption is the starting point for the slab on private ground, so the coating scope is split at the edge of the public right-of-way, and each side is checked on its own track.

Permits and rules in Snohomish

We confirm two tracks before anything is booked. The private slab is checked against the state exemption and its height and basement conditions. The street end is checked with Public Works under SMC 12.20.130, and any right-of-way work is checked under SMC 12.12. If a soft base or a drainage fix is bundled into the job, it goes through the same review, so we look at the full scope before the quote goes out.

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

Questions from Snohomish homeowners

Does a Snohomish overlay that reaches the apron change the permit?

It can. SMC 12.20.130 covers altering, repairing, and replacing a driveway, sidewalk, curb, or gutter, so a coating that runs onto the apron goes to Public Works before any work starts. A coating held inside the private slab is measured against the state exemption instead.

Does a Snohomish overlay on a slab over a lower story need a closer look?

Yes. The state exemption for a driveway covers a slab that rises no more than 30 inches above adjacent grade and has no basement or story beneath it, so a slab over a lower level is checked against those conditions before we quote.

What happens to a lifted sidewalk panel in front of a Snohomish overlay?

A coating does not repair a lifted panel. Under SMC 12.20.010 the abutting owner carries the sidewalk’s repair, and under SMC 12.20.130 any repair or replacement needs a Public Works permit before work starts, so the panel is inspected and kept out of the coating scope.
