"I needed to stabilize a slope. Norberto presented a plan for a retaining wall and drainage that was both functional and attractive. He provided a detailed bid for labor and materials that was competitive with several other companies He and his crew completed the job efficiently while taking care not to damage existing shrubbery and ornamentals. Norberto is professional and easy to work with. He was very good about coordinating with me. I have and will continue to use his company for other projects."

Excavating questions, answered by experts

Call 811 to locate and mark the gas lines at least three days before digging. In many areas, you can dig within 18 inches of the lines, though in some locations, the distance may be further. Check local regulations, as you may need a utility company representative onsite when digging. Document your calls to 811 and precautions taken to avoid gas lines. A homeowner can be held liable for hitting a gas line in some cases, but contacting the proper authorities and following all guidelines can offer protection.

Excavation and grading are both generally necessary for designing your foundation, and leveling the ground where your foundation will go. These steps can also prepare the area by removing vegetation and anything else that could interfere with your home’s foundation.

You can dig 60 to 80 linear feet by hand per day depending on the depth. Digging a 100-foot trench by hand will take you two work days, but it can take longer if you have heavy or rocky soil. If you’re digging a deep trench or one that’s over 100 feet, consider renting a mechanical trencher, such as a walk-behind or ride-on, or calling a pro for help. 

The best type of soil to build on is a mixture of sand and clay, known as loam soil. Loam soil has the best combination of these soil types to build a foundation on. The clay particles help with water retention, so it won’t erode like sandy soil might, and the sandy particles help with drainage, so you won’t see unsafe soil expansion or have an increased risk of leaks from water sitting against your foundation.

A walk-behind trencher can cut through roots as long as they’re not too thick, making a project much easier than digging with a shovel and other hand tools. Assess your terrain and the number of trees in the surrounding area to determine if a walk-behind trencher will ease the job. Digging a trench by hand is much more time-consuming and labor-intensive.
