"Outstanding work, respectful and professional crew, easy to work with, very fair pricing. They did a lot of excavating and spreading of dirt & gravel, built a beautiful rock wall along with site prep for a shop spot. We would hire them again, we highly recommended this company,"

"They put in new drains and a dry well for our driveway, carport, and front yard. When the first dry well wasn't large enough to hold all the runoff from a heavy storm, they came back and added a second for free. Excellent customer service, very responsive, good work."

"When choosing a general contractor, we were looking for someone to complete multiple jobs in a timely manner, with a solid work history and good reviews. Eric's Quality Building checked all our boxes. Eric provided a fair quote for both a concrete patio extension and a patio cover. Both of our projects were completed in a fast and efficient manner, with the quality of work and customer service provided being stellar. Eric is a younger guy, but he and his crew do a great job. I will use Eric for future projects, and I suggest you hire him for your next project big or small."

"Holmes Concrete & Excavation designed and installed a stamped, colored concrete walkway around 75% of our house. The walkway passed through our front and rear gardens and also covered the south end of our house where we keep our trash bins and air conditioner unit. The walkway was well designed and helped tie together the exterior of our house in a functional, aesthetically appealing way. James Holmes helped us choose a color for the concrete that matched the exterior of our house. Overall, the final product exceeded our expectations. James and his team were professional, timely, and did a great job communicating the stages of the project. We have 2 dogs and they also did a good job temporarily closing off a portion of our yard to allow the dogs to use the yard without it negatively impacting the project. We are very happy with the work and would highly recommend Holmes Concrete for a variety of concrete related work. We would definitely hire them again."

FAQs for excavation major grading or resloping projects in Portland, OR

The time required to dig a 100-foot trench varies significantly depending on soil conditions and the type of equipment used. Most residential projects using walk-behind trenchers take between two and four hours for this length. Soft soil allows for faster progress, while rocky or clay-heavy ground requires more time. If you're new to operating trenching equipment, allow for additional time to learn the controls and work at a comfortable pace.

Standard trenches measure between 12 and 24 inches deep and approximately eight inches wide, which is within the capability of most walk-behind trenchers. The exact depth capacity varies by model and manufacturer. For specialized projects, such as French drain installation, an 18-inch depth is standard. Always confirm the specific depth capabilities of your rental equipment before beginning your project.

While formal certification isn't always required, basic training is highly recommended before operating trenching equipment. Most rental companies provide operational instructions and safety guidelines when you pick up the equipment. If you're uncomfortable with heavy machinery or have a particularly challenging site, consider hiring professionals. For those proceeding with DIY trenching, start slowly and practice in an open area before tackling your actual project.

For typical residential irrigation systems, a walk-behind trencher is generally sufficient. These systems require trenches between six and 12 inches deep, depending on your local frost line and system specifications. The narrow trenches produced by walk-behind models are ideal for installing standard irrigation pipes. For larger properties or particularly challenging soil conditions, consider a more powerful model.

Contact your local utility marking service before any digging project to identify underground hazards. Remove obstacles, rocks, and lawn furniture from your work area and planned trench path. Mark your intended trench line using stakes or marking paint to ensure straight, properly aligned trenches. Having a plan for soil disposal and eventual backfilling will also streamline your project and minimize rental time.

First-time operators often encounter issues with blade clogging in wet or clay-heavy soil. Hitting unmarked underground utilities can cause service disruptions and create safety hazards. Many DIYers underestimate project timelines, resulting in rushed work or additional rental days. Trench wall collapse can occur in unstable soil conditions. Following manufacturer guidelines, maintaining appropriate speeds, and thoroughly preparing your site can help avoid these common complications.
