Concrete Overlays in Maple Valley, WA

Concrete overlays in Maple Valley: what to know

Most of the city’s housing was built between 1990 and 2010, so a typical slab has been through decades of wet winters. One that has stayed flat and tight has probably kept its base, which is what an overlay depends on. A slab that dips, tilts, or has cracks that keep opening is a replacement job, because the surface coat follows whatever moves below it.

Water quality is the local catch. Lake Wilderness drains to Jenkins Creek, which the city’s stormwater plan says is on Ecology’s 303(d) list of impaired waters for fine sediment. Prep slurry and rinse water have to stay out of catch basins. At the sidewalk, the road standards call for Portland cement concrete or an approved equal, so a coating on a public walk is the city’s call.

Permits and rules in Maple Valley

Resurfacing changes neither a slab’s footprint nor its grade, which is why it usually sits outside the building permit rules. Hard-surface math can still matter: Maple Valley’s drainage review starts at 2,000 square feet of new or replaced impervious surface, and whether a resurface counts as replaced is for the city to say. The apron and sidewalk are right-of-way. Before pricing, we confirm with Public Works and Community Development how they treat your slab.

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

How we approach it

Tap-test the slab and mark cracks that still open and close
Contain prep slurry and rinse water so none reaches a catch basin or ditch
Hold the overlay at the right-of-way line unless Public Works approves the apron
Match thickness at the garage door and porch so water still drains away

Questions from Maple Valley homeowners

Can I resurface a Maple Valley driveway poured in the 1990s?

Often, if the slab is flat and the cracks have stopped moving. Most of the city’s homes date from 1990 to 2010, so many slabs fit that description. A section that sank or heaved gets replaced first, because an overlay follows whatever lies beneath.

Where does overlay wash water go in Maple Valley?

Not into the street. Stormwater here drains to Jenkins Creek, Lake Wilderness, and other waters, and the city runs its own surface water utility. Slurry and rinse water should be contained and kept away from catch basins and ditches.

Can my Maple Valley sidewalk be resurfaced instead of replaced?

That is the city’s decision. The sidewalk is public right-of-way, the road standards call for Portland cement concrete or an approved equal, and work there needs a right-of-way construction permit from the Public Works Director.
