"Konnaugh and his team were a pleasure to work with. They showed up on time, and after demolishing and removing a hot tub and a chicken coop, they left my yard practically spotless! They did such a great job, I would highly recommend them to anyone looking for junk removal or yard cleanup ??"

""ABSOLUTELY SUPERB" - Ken and Rowen were contracted to install Round River Rock Stone along approximately 180 feet (both sides) of my driveway. Ken promptly answered my request for an estimate. The next day he arrived to view the job and was very thorough about understanding my expectations for the project, He offered advice and is very knowledgeable about how to do top quality work. After my reviewing other estimates my decision was to go with McAdams Excavating, Ken and Rowen arrived as promised and quickly began meticulous work. Material was excavated to provided a 3 inch depth of stone, landscape fabric was installed, finally the stone. The duo were meticulous in all facets of this project and it looks absolutely gorgeous! Do not hesitate to hire this company!!!"

"We hired Tyler and his crew from Quantum Contracting LLC to build a 10 x 12 pool deck and they did an awesome job. Hardworking, pleasant and professional. They cleaned up the area every night when they left and when the project was completed. Very skilled in their detail and carpentry work. We are so pleased with the end result and look forward to using it this summer. We would hire them again for any project and we highly recommend them. Paula and Stephen Russell"

Excavating questions, answered by experts

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.

Hardscaping often requires preparation of the ground in the area where the feature is being installed. This can include digging, compacting, and leveling the soil, ensuring adequate drainage, and removing any existing plants. The extent of preparation needed will depend on the type and size of the hardscaping feature being installed.

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.

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. 

You should dig 3 to 6 inches deep for plastic edging. Dig as wide as you need to fit your plastic edging into it—2 inches is usually sufficient.
