Asphalt and concrete contractor in Alameda County

Low-lying land around the Oakland Estuary, Alameda and the bay shoreline sits on soft, fine-grained bay mud. Pavement built over ground like that depends on a solid aggregate base and a subgrade that can really carry the load.

It's also where a site walk can't tell you everything. Some conditions only show up once the old pavement comes off. That's why, on removal and replacement projects near the shoreline, we talk through up front what happens if the subgrade isn't what everyone expected, so there are no surprises later.

Work in downtown Oakland happens in the public right-of-way under City of Oakland Department of Transportation requirements, with traffic, transit and pedestrians moving all around it.

At 226 13th Street, we ground and repaved four city streets totaling 35,350 SF to 2 inches and put down fresh thermoplastic markings. The key throughout was keeping public access open while meeting the City's requirements. Most of the planning went into phasing; the paving was the straightforward part.

In the Hayward and Oakland hills, grade comes into every decision. On a slope, uneven milling depth shows up right away as a rough ride and sends water running where it shouldn't.

On Arbutus Court and Quercus Court in the Hayward Hills, we milled 72,000 SF of City of Hayward streets 100% to a 2-inch depth and repaved them full width instead of patching in strips. That leaves no patchwork seams for water to get into.

At Longwood Elementary in Hayward, we removed and replaced 2,300 tons of asphalt, plus cement and lime treatment of soft subgrade we found during demolition, all inside a three-week window.

The Crossings HOA in Fremont needed a different approach: 34,500 SF of targeted 4-inch repairs and seal coat instead of a full resurface, which kept the community's spending focused where it was needed.

Bay Ship Co. in Alameda needed heavy-duty industrial pavement and new street installation on a working waterfront site. Three projects in one county, each scoped differently.
