01 · Driveways

Driveways built
for Seattle winters.

Your driveway is the single biggest slab on your property and the hardest working one. We pour driveways that handle the rain, the freeze-thaw, the delivery trucks, and 30+ years of backing in.

The pitch

A driveway is a 30-year slab.
Pour it like one.

Most cracked driveways aren't a concrete problem. They're a base problem. Proper subgrade compaction, gravel depth, reinforcement, and expansion joints — skip one and you'll see the crack a year in. We don't skip them.

02 · What we do

The full range.

Broom finish

The Seattle classic. Non-slip when wet, ages beautifully, blends with any house style.

Exposed aggregate

Pea-gravel exposed finish. Adds texture and grip. Premium look for front-of-house driveways.

Stamped concrete

Brick, stone, slate patterns. Colored integrally so chips don't show a different shade.

Tear-out & replace

Ripping out a failing slab is half the job. We remove, haul, regrade, and re-pour clean.

04 · Our standards

Non-negotiable.

  • 01

    Proper subgrade prep — 4+ inches of compacted crushed gravel, every time.

  • 02

    Fiber mesh or #4 rebar on a grid — a driveway without reinforcement is a cracked driveway in waiting.

  • 03

    Control joints cut within 24 hours of pour — the right depth, the right spacing.

  • 04

    A slope that drains. We won't pour a slab that ponds water against your garage door.

  • 05

    Curing compound or wet-cure — every slab we pour, regardless of temperature.
