Our Legacy
Building the backbone of Washington, Idaho, and Oregon since 1982
Built on Grit. Driven by Values.
Over the decades, what began as a single paving crew has grown into a vertically integrated regional power—delivering premier asphalt and aggregates, supported by a family of companies providing full-scale heavy civil, ready-mix concrete, and traffic management solutions.
Family Owned. Deeply Rooted.
Central Washington Asphalt was founded with a simple belief: do the job right, take care of your people, and stand behind your work. Those values came straight from the Maiers family—a name already rooted deep in the Northwest’s construction history—and from early leaders like Elwyn “Sonny” Walker, whose integrity and steady leadership helped shape our foundation.
Earned, Not Given.
Where others chased shortcuts, Central Washington Asphalt built a reputation the long way—through early mornings, tough jobs, and craftsmanship that lasts. Over the decades, our crews—backed by our unified family of companies—have paved highways, strengthened communities, and delivered projects for contractors, municipalities, and commercial clients who know they can count on us when it matters.
Independent Scale. Local Accountability.
Central Washington Asphalt stands apart in an industry dominated by national corporations — independent, local, and accountable to the communities we serve across Central and Eastern Washington, Idaho, and Oregon. Our independence means faster decisions, flexible solutions, and a crew that shows up because this is our home. We build relationships the same way we build roads: with grit, integrity, and a commitment built to last.
What We Do.
From major roadway paving to site development—and turnkey concrete structures delivered through our family of companies—we handle projects of any scale with pride and precision.
Every job is powered by our own aggregate pits, asphalt production, and on-site quality-control labs to ensure dependable performance from the ground up.
The Team Behind the Work
Central Washington Asphalt is more than a construction company. We’re a team of operators, laborers, drivers, estimators, and leaders who take pride in building the backbone of our region. Many of our people have spent decades here, growing their skills, mentoring the next generation, and proving that hard work still means something.
Build it right. Build it strong. Build it to last.
Since 1982, that core mission hasn’t changed. That’s Central Washington Asphalt.
Behind every project is a dedication to lasting performance. Our Quality Management team designs every mix with sustainability in mind, monitoring Reclaimed Asphalt Pavement (RAP) production across all locations to optimize efficiency without sacrificing strength.
