Outdoor spaces
built to last
a lifetime.
Three decades of driveways, patios, retaining walls, and synthetic turf for homeowners across Walnut Creek, Danville, Pleasant Hill, Concord, Pleasanton, Livermore, and the East Bay.
Four crafts. One crew.
From the first pour to the final plant, every project is handled by the same team you'll meet at the estimate.
A family business with a long memory.
Ken started A·K in 1991 with one truck and a reputation to build. A proud UC Davis graduate, he brought a builder's eye and an agriculturalist's respect for the land to every project. Three decades later, we're still answering the phone, still showing up on time, and still pouring concrete the way it's meant to be poured — by hand, by craftsmen who care.

"From start to finish, the team was professional, efficient, and committed to delivering top-notch results. Our project turned out better than we could have imagined — flawless concrete work and beautifully designed landscaping."
"Ken and his crew just installed concrete walkways in our back yard — and I mean a LOT of walkways. They did what they promised, when they promised, for the price they quoted. Our walkways look fabulous. Highly recommended."
"I've used Ken at various times for several different projects through the years. He's friendly, professional, and keeps his word. Over the 20 years I've known him, many of his crew are the same guys I first met. Highly recommend."
