Pacific Northwest Driveway Requirements
Redmond driveways face specific challenges: 35+ inches of annual rain, King County soil that stays saturated for months, moss and algae on shaded concrete, and tree roots from Douglas fir and cedar canopy near older slabs.
- Rain saturation: drainage pitch is non-negotiable
- Moss and algae: broom texture and proper drainage reduce establishment
- Tree root proximity: Pacific Northwest tree canopy means root assessment matters at base prep
"Our driveway was mossy and slippery and water kept sitting near the garage after every rain. Kevin showed us the original pitch was nearly flat. He rebuilt the driveway with a proper slope toward the street, used a broom finish for traction, and the moss hasn't come back since. The garage stays dry now."

Why does concrete grow moss in the Pacific Northwest?
Concrete grows moss when moisture stays on the surface long enough for moss and algae to establish. Redmond rain, shaded Douglas fir and cedar canopy, and flat surfaces that don't drain quickly create ideal moss conditions.
When is the best time to pour a concrete driveway in Redmond?
July through September is the most reliable Redmond pour window. Spring and fall work can happen during dry weather windows but requires more scheduling flexibility.
Can concrete driveways be poured in Redmond outside the summer window?
Yes, during dry weather windows in spring and fall. The preference is July through September when Pacific Northwest summers are reliably dry. Kevin confirms timing at the estimate based on current forecast.
How long does driveway replacement take in Redmond?
Most residential driveway projects take 2-3 days for prep and pour. Plan on 7 days cure before foot traffic and 28 days for full structural cure.
