Paving that holds up
to Carnation weather.
Carnation is rural Snoqualmie Valley at the confluence of the Tolt and Snoqualmie rivers, with mostly farm and acreage properties. Driveways here are typically long, sometimes half a mile or more, which makes chip seal the most cost-effective surfacing choice for most owners. River valley drainage and seasonal high water table are real design constraints.
Pacific Northwest weather is hard on pavement. 150+ rain days a year, saturated subgrade through the wet months, occasional hard freezes, and moss that grows on anything that sits damp. Every one of those forces chips away at thin, poorly-installed asphalt, and you see the damage in alligator cracking, sunken edges, moss-eaten surfaces and standing water inside three to four years.
Our mix design, base depth and drainage planning are tuned for those realities. In Carnation and across Greater Seattle we run thicker lifts, compact in measured passes, crown surfaces for shed-off, and plan the subsurface drainage so water doesn't sit under the mat and eat the base. The finished pavement looks right on day one and stays tight for decades.

No. We come to your Carnation property, walk the site with you, check drainage and subgrade, and write up a real number, usually same day. Free and no obligation to book.
Western Washington paving season runs April through mid-October, with surface temps above about 50 degrees. We watch the forecast and schedule around wet windows. Chip seal needs warmer, drier conditions, May through early September is the sweet spot.
We can handle emergency patch work through the winter using cold-patch mix. Proper hot-mix repairs and full paving wait for dry weather above 50 degrees. If something needs to hold you over until spring, we'll take care of it.
