Michael and his team were a god-send. Incredibly professional, efficient, extremely fair with pricing, and really worked with me when the county was giving me issues with my project to replace my gas line. I appreciated his direct communication, and throughout an unnecessarily frustrating process (all the fault of the city and my utility company) Michael always came to me with solutions and was even able to help put together a successful reimbursement claim against PGE for their errors—extra time he committed to my cause which was above and beyond. 10 out of 5 stars in my humble opinion, I would highly recommend utilizing his services for any job. The final result of my project was better than I could have expected.

Excavation & Trenching FAQs

Angelo Underground is not just an excavation company; we are a team of certified underground contractors specializing in utility trenching and excavation projects. Our commitment to professionalism, quality workmanship, and clear communication positions us as industry experts. With certifications like DPI and Avetta, we ensure safety and efficiency on every job, aiming to be the contractor you remember for making your projects run smoothly for years to come.

These certifications are not just acronyms; they represent our commitment to excellence and compliance. Being a licensed contractor and holding DBE, MBE, and ESB certifications means we meet federal and state requirements for certain projects. This can be crucial for excavating contractors looking to fulfill specific project goals. Our DPI and Avetta certifications further underscore our dedication to safety and quality in underground construction.

Our approach to utility trenching is comprehensive. We provide turn-key solutions that minimize the need for multiple subcontractors, from saw cutting to patching back. This integrated service model adds value for general contractors by simplifying project management and ensuring seamless execution and customer satisfaction. We do not offer trenching for residential retaining walls.

Electrical trenching is a complex task that requires adherence to specific codes regarding trench depths and conduit spacing. Whether it's a simple solar trenching job or a complex duct bank pour, our expertise ensures that the project is completed correctly, meeting all local agency certifications and requirements.

Safety is paramount in gas line trenching. We utilize hydro vac trailers for potholing to accurately identify utility depths before trenching, avoiding the risks associated with hand digging. This careful approach ensures the integrity of existing lines and the safety of our team and the surrounding area.

We focus on commercial needs, providing services for public works and city improvements, including sewer taps into the main. Our extensive experience with the City of Portland enables us to offer a seamless process from project initiation to completion, with a strong emphasis on commercial applications.

Hydrovac excavation is a safe, efficient alternative to traditional trenching methods, especially around live utilities. We offer both vac truck and more affordable vac trailer services, providing the same high-quality results at a reduced cost. This service is ideal for clients who need quick, cost-effective utility potholing.

Our vacuum excavation trailers are a more economical option compared to vac trucks, offering a 40% reduction in hourly rates and lower dumping fees. They are perfect for projects requiring only a few potholes, saving our clients time and money while still delivering precise results.

Angelo Underground offers a comprehensive range of residential services tailored to meet the needs of homeowners in Portland. Our residential services include installing new power and gas conduits, which may involve trenching across streets or through challenging terrain. We also specialize in solar power trenching for rural homes, where our expertise with excavators ensures a smooth installation. Whether it's for utility upgrades or new installations, our team brings the same level of professionalism and quality to residential projects as we do to our commercial endeavors. We do not offer retaining wall services.
