Sammamish Plateau Concrete Work
Sammamish and the Plateau are a regular fit for Kevin when route and scope make sense. The area east of Redmond has grown quickly, with many newer homes built from the 2000s through the 2020s on larger lots, sloped yards, and significant Douglas fir and cedar canopy.
Newer homes here often have builder-grade concrete that homeowners are already upgrading or replacing after one or two wet seasons reveal drainage issues. A patio that looked acceptable at closing can start holding water once the landscape settles, roof runoff patterns change, or a shaded yard keeps the slab damp through winter.
“Our newer Plateau home had a builder-poured patio that was already holding water and starting to grow moss after two wet seasons. Kevin replaced it with corrected drainage pitch and exposed aggregate. The finish was clean, and the drainage issue did not come back the following season.”

Why Plateau Elevation Changes the Concrete Plan
The Sammamish Plateau sits higher than the lower Eastside corridor communities. It gets slightly more rainfall, stays cooler, and often stays wetter longer in spring. Wet-season saturation lingers, which makes base prep and drainage even more important on the Plateau than on lower Redmond or Kirkland properties.
On large lots and sloped yards, Kevin looks closely at runoff direction before forms are set. Water should not collect at the patio edge, hold against the house, or run across a driveway in a way that creates winter slick spots. Broom finish and exposed aggregate both help with traction, but pitch and base support are what keep the slab usable through wet months.

Why does concrete fail quickly on the Sammamish Plateau?
