Excavation Contractor in Colusa Junction, CA | Pina Excavating

Colusa Junction sits at the CA-20 and I-5 interchange. This location draws commercial truck stops, agricultural processing operations, and industrial yards. Every one of these properties eventually needs site work done. That includes old building teardown, concrete slab demolition, new pad grading, and stormwater management.Most general excavating contractors do not carry a CSLB C-21 demolition license. Without it, they cannot legally tear down concrete block structures, break out reinforced slabs, or demo old commercial buildings. They have to hire a subcontractor to do that part. This adds cost and creates scheduling problems.Pina Excavating holds the C-21 license. We also hold the C-12 earthwork license. This means we can demo the old structure, grade the new pad, and dig the retention basin all under one contract, one crew, and one project manager.Dos Rios Gas focuses on pipeline maintenance. They are not a demolition and earthwork contractor. We are.

Licensed Demolition and Industrial Site Work at the CA-20 and I-5 Interchange

Commercial Demolition

Our C-21 license covers structural demolition of CMU buildings, reinforced concrete tilt-up panels, steel-framed industrial buildings, and large concrete slab foundations. We use a hydraulic breaker to break concrete and a demolition grapple to sort and load debris. Concrete and masonry go to a recycled aggregate facility.

Industrial Concrete Slab Preparation

Industrial slabs at Colusa Junction support heavy forklifts, loaded semi-trucks, and agricultural processing equipment. Our slab prep: demolish and remove existing deteriorated slab (C-21), excavate and replace soft subgrade with engineered fill, compact to 95 percent density, place 6 to 8 inches of Class II base, laser grade to plus or minus one-eighth inch.

Stormwater Retention Basin Excavation

Commercial sites disturbing more than 1 acre need a SWPPP-compliant stormwater detention basin. We dig basins to the size and depth 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 Colusa Junction, CA

What does a C-21 demolition license allow Pina Excavating to do in Colusa Junction?

A CSLB C-21 license authorizes us to demolish structural buildings, break out reinforced concrete slabs, remove concrete masonry unit walls, and clear all below-grade footings and foundations. Without this license, a contractor can only do earthwork. With it, we can do the full scope from structure teardown to finished grade under one contract.

Does commercial demolition near Colusa Junction require an asbestos inspection?

Yes. Colusa County requires asbestos survey documentation for commercial structures built before 1980 before demolition permits are issued. If asbestos-containing materials are found, a licensed abatement contractor must complete removal before our demolition work begins. We coordinate with your project team to sequence this correctly.

What size retention basin does a 3-acre commercial site need at Colusa Junction?

For a typical 3-acre commercial site in Colusa County, a detention basin of 0.3 to 0.6 acre-feet of storage is a common range. We dig to the dimensions on your approved civil engineering plan.
