"Eric was right on point and identified the solution and scope of work very promptly. He is a very good communicator via text and in person. I thought his pricing was very fair. He worked to install gutter on my roof, drainage piping, and a trench drain on the side of my driveway to mitigate erosion. He rototilled, fertilized, and installed sod on my formerly eroded front lawn. The work came out fantastic and my neighbors keep complementing me on how nice my house looks now."

"Tree stumps have been removed and the areas look like the stumps had never been there. It was done professionally. The proprietor called me shortly after I posted the project Sunday evening. We agreed that he would call me early Monday afternoon. He did so and asked if he could bring his equipment should we agree on a price. That did happen and I am very satisfied!"

Excavating questions, answered by experts

A joint utility trench, or joint trench, is a long, buried ditch on a property that contains two or more utility lines rather than running the lines in multiple trenches. Some utilities, like gas and electric or electric and communication lines, are better suited to joint trenching, while others, like water and sewer, are not allowed to be in the same trench.

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.

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.

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.
