Commercial Excavation Contractor in Wilson, CA | Pina Excavating

Wilson is along the CA-99 corridor north of Sacramento. This stretch sees steady commercial development. New retail pads, small industrial facilities, and agricultural processing buildings all need professional site preparation before concrete or steel goes up.Commercial site work in this area has three phases. First, the existing structure or pavement must come out. Next, the sub-base must be graded and compacted to bearing capacity. Then the drainage system must be in place before the paving or structural crew arrives.Pina Excavating does all three phases. Our C-21 demolition license covers the tearout. Our C-12 earthwork license covers sub-base grading and compaction. We have also built stormwater detention basins that satisfy Regional Water Quality Control Board permit requirements.Dos Rios Agricultural Services focuses on farm drainage work. They do not carry C-21 authority for commercial concrete demolition. We do.

Commercial Sub-Base Grading, Asphalt Tearout, and Stormwater Detention Basins in Wilson, CA

Full C-21 Authority for Commercial Demo Through to Finished Grade in the CA-99 Corridor

Asphalt and Concrete Tearout (C-21)

We mill or break out the failed asphalt and haul it to certified recycling facilities. Reinforced concrete driveways and aprons are broken with a hydraulic hammer and removed. After tearout, we proof roll the exposed subgrade to locate soft spots before the base goes back in.

Commercial Sub-Base Grading

A commercial parking lot sub-base for standard vehicle traffic needs 6 to 8 inches of Class II aggregate base compacted to 95 percent. A heavy truck yard needs 10 to 12 inches. We coordinate with your project's geotechnical engineer to meet the specified base depth and compaction. We document each compaction layer with nuclear gauge tests.

Stormwater Detention Basin Excavation

Commercial projects disturbing more than 1 acre along the CA-99 corridor need SWPPP-compliant stormwater management. We excavate basins to the dimensions on your civil engineer's drainage plan. We also grade the earthen berm and install the outlet control structure.

Common Questions About Commercial Excavation in Wilson, CA

What SWPPP requirements apply to commercial grading work in Wilson near CA-99?

Projects disturbing 1 or more acres in Yuba County must file a Notice of Intent with the State Water Board and implement a SWPPP. This includes erosion control BMPs and a stormwater detention basin sized to hold the design storm on-site. We coordinate the SWPPP document requirements with your civil engineer.

Can Pina Excavating do both the asphalt demolition and the new sub-base in Wilson?

Yes. Our C-21 license covers asphalt and concrete demolition. Our C-12 license covers sub-base preparation and compaction. We perform both in sequence under one contract. This eliminates the cost and scheduling delays of hiring a separate demolition subcontractor.

How long does a commercial parking lot sub-base last in Wilson's Yuba County climate?

A properly prepared commercial parking lot base with 6 to 8 inches of Class II aggregate compacted to 95 percent typically lasts 15 to 20 years before needing reconstruction. Base life depends heavily on drainage design. A base with good drainage outlasts one with poor drainage by 5 to 10 years.
