"Toby cleared 50 years of deadfall branches and established a driveway on a 1/4 acre lot in one day. Amazing. Brought him back for stump removal, grading and to establish a surface drain. Artist with an excavator. Perfect grade and solved erosion and drainage problems. Worked with B.C.X. gravel and prepared a perfect pad and safe driveway for our trailer. I trust him for anything else I need in the future. Reasonable rates. Doesn't waste your time. Extremely responsive to short notice schedule changes. A joy to work with someone so professional."

"Ray is very personable and a professional demo expert. He demolished two structures, a shed and a giant stick-built outdoor playhouse. All work that was agreed to was completed on time, all waste hauled away, and the area left better than when he started. Iâ  ll be adding Ray to my personal list of trusted contractors and would easily hire him in the future and recommend him to anyone I know thatâ  s in need of demolition. Thank you, Ray, and crew, I'm very happy with the results!"

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.

The digging depth will depend on the size of the trencher you use. Even smaller units can dig up to 4 feet deep, which is plenty for a DIY job. However, much larger trenchers can reach a depth of 18 feet and are better used by a team of pro contractors, not a single DIYer. As with all home improvement projects, use the right tool for the job and proceed with caution.

Septic drain lines (or leach lines) are typically buried between 18 and 36 inches underground, and should be at least 6 inches below the surface. These pipes are perforated and surrounded by filtering materials like sand or gravel. Burying the lines at this depth helps minimize odors and allows bacteria and other biological processes in the soil to effectively treat the wastewater. Burying lines too close to the surface can cause issues unless the soil is very compact and stable.

How deep your septic system needs to be into the ground depends on several factors. In extremely cold environments, the tank needs to rest below the maximum frost line, which can be up to six or eight feet deep. The standard burying depth for most systems is between a few inches and four feet below ground level. Depth can also depend on the slope of the landscaping and other property variables. 

Whether you grind or dig up and remove your tree stump depends on your landscaping goals. Using a stump grinder leaves the root system in place for it to decompose over time, whereas digging up the tree stump removes the roots and the stump. Overall, stump grinding is a far simpler process since you won’t need to deal with the roots. Stump removal will make your yard look like a demolition site, but you’ll have an easier time replanting in the same place as your former tree.
