"Double M Groundworks did a fantastic job replacing an old retaining wall. They also did grading work around the foundation of my home to improve water drainage away from the house. The work was completed in two days. I am very pleased with their work and professionalism. I will use them again if a need arises."

"We had been looking for someone to repair a damaged step on a front porch. We tried about 4-5 companies and they either said no the job was too small or they had no time or they didn’t respond. Shawn Hiatts first response to us was I think it is going to warm up next week, I can get it done then. He showed up and did the work. He went above and beyond by making the step a little wider, which was very acceptable to us. Less chance of falling off as the other step was not so wide. Also we were aware of needing dirt work done around the house and rock out over it. He told us that we might want to get dirt work done to save damage layer. We told him yes we knew it needed done. He offered to do it at a very reasonable price. That evening the dirt work was done and the next morning rock was down. He is very efficient and professional. We will definitely use him again when we need more work done!!"

Excavating questions, answered by experts

Sewer lines can be buried anywhere from 18 inches to 8 feet deep, with a common average depth between 18 and 30 inches. The exact depth depends on local factors like climate and soil type. In colder regions, pipes must be buried deeper (below the frost line) to prevent freezing, sometimes as deep as 8 feet. The digging depth can also impact the cost of sewer line replacement. To find the specific depth for your property, you can check the building plans for your system, which should be on file with your city or local sanitation department since permits are required for installation.

Most professional excavation teams will charge between $8 and $15 per cubic yard. Calculate the cost by finding the volume of your pool—width x length x depth—and dividing it by 27. Then, multiply the price by the cubic yards from your equation. Budget for complications like a rocky lawn, hard-to-access pool area, or high local labor prices.

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 trench that is less than 5 feet deep often doesn't require a protective system. Most residential trenches will not go this deep (the typical residential drainage trench is just 18 inches deep). In the event that an excavator needs to dig more than 5 feet beneath the surface, a protective system is required unless the excavation is in entirely stable rock.

Trenchers can dig holes as narrow as 4 inches or as wide as 4 feet. Check the specifications of the trencher you rent or buy to determine how wide it will cut into the landscape. Better yet, let the excavation company know how wide you’d like the trench to be, and they can help you choose the right trencher for the job (or do it for you).
