"The attention to detail of the work was top rate. We had three sink holes in our yard that they took care of for us, as well as spreading loam for us to start a lawn in the spring. I very highly recommend McAdams Excavation."

"We just moved into our home and wanted to get our backyard graded. Kyle came by right after I talked with him and gave us a great quote. He had his crew there shortly after. He frequently checked in while the project was going on, and addressed any questions and concerns I had. Tony did a fantastic job with the grading, and was extremely knowledgeable and professional. After this we were so pleased that we had them also spread loom and put in some steps. Leo did a great job spreading and smoothing out the loom. All had great work ethic, and it was obvious they knew what they were doing. After the job was done they still checked in to make sure everything was good, and anytime I had a question they were quick to respond. Would highly recommend K&J. 5 stars!"

Excavating questions, answered by experts

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.

A mini excavator can dig between 5 and 11 feet deep, depending on the type and size of the mini excavator. Mini hydraulic excavators are more powerful and can reach deeper into the earth, but electric models have a more limited range. Mini excavators over two tons in size are also more powerful and able to dig as deep as 11 feet.

Yes. A metal detector is one of the quickest and easiest ways to find your septic tank. However, metal detectors can be too expensive (costing upward of $300 in some cases), and not everyone has a metal detector just lying around. If that’s the case for you, you can also take a long metal rod and poke it into the ground at regular intervals until you hit something—likely your septic tank lid.

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.

No, you typically cannot use metal detectors to find your sewer line. Most sewer lines are made of non-metallic materials such as PVC, clay, or cast iron, which are not detectable by standard metal detectors. Metal detectors are designed to locate metallic objects, so they won't be effective for identifying the path of a non-metallic sewer line. To locate your sewer line accurately, it's best to use other methods.
