"Daniel was awesome to work with. He came out and provided a solid estimate in a timely fashion. We had an unexpected sprinkler line that was in the middle of our excavation area and he took care of that. He also provided the materials for a retaining wall that we hadn't initially planned for, and he added that to the project scope without issue. I will definitely reach out to Daniel if we have another project like this one."

"I hired Paul to help me with multiple projects. He mowed our 2 acre field property when the grass was 4-5ft tall, which gave us easy access to our whole property. He regraded our driveway with approx 20yrds of gravel, leaving it smooth enough I could easily ride my street bike on it. He also excavated a small seasonal pond on our property and removed enough dirt to triple it in size, giving us a year round pond. Very happy with the results of all his work, worth every penny. I will be using Army of One again."

Excavating FAQs, answered by experts

Depth is not a qualifying component of evacuation. Any human-made cut, cavity, or depression in the earth’s surface is considered excavation. The hole from excavation can be any size, shape, or depth. Excavation is used to create foundations, reservoirs, drainage ditches, and roads. Long, narrow excavations are called trenches and are often used for underground utilities.

You can bury underground electrical wire six inches deep—but only if you use a rigid metal electrical conduit. For rigid, non-metallic conduits, bury the wire at least 12 inches deep. If using an underground feeder cable rated for direct burial, you'll need to place it at least 18 inches deep, as it has no conduit for extra protection.

In the United States, a depth of 36 inches (three feet) for underground water lines is the accepted industry standard. This depth varies from location to location based on local conditions. In areas with colder winters, they may be buried deeper to prevent frozen well water pipes : This is usually at least six inches below the frost level. The International Plumbing Code calls for a minimum of 12 inches below grade.

Prior to excavation, you should prepare the dig site and call 311 before you sign anything.

To get your site ready for excavation, you should move anything in the area that isn’t affixed to the land. You can save money on the excavation by removing hardscaping, including walkways, decks, concrete patios, and paver patios.

Before you carry out any digging, you should call 311 to confirm that there are no utility lines running through your excavation site. Skipping this step could lead to severe injury and property damage if your excavator hits a water, sewage, or gas line.

Most residential basements are 8 to 10 feet deep. You can dig deeper depending on building codes, but it does become more difficult. You’ll likely need to install stronger foundation walls and additional supports to handle the increased load. Depending on the water table, you may also need a water management system. Clay soil can support a deeper foundation than sandy soil. A structural engineer will be able to tell you the maximum, feasible depth.
