"he arrived on time went straight to work after i showed him what I had imagined. The work he performed exceeded the original description but he still managed to give me a driveway at near 8 degree to 12 degree and cleared a nice parking area out as well."

"Knew how to anticipate unusual problems with system. When rock was encountered they rolled with it and did not charge extra. Great job of cleanup afterward - burned brush after clearing, then carefully buried remains of the fire. The TN environmental inspector obviously knew them well and had approved their work before. OnSite also guided me through the permitting process. They were easy to work with and seemed to have a lot of experience. They did a good job of explaining why the new installation had to be done the way it was done."

"I had an old raggedy 2500 square foot house I needed tore down and the ground completely leveled and MGT Enterprise were life savers. When I called and asked for a quote they were there with bells on to give me my free estimate. I called several other excavation companies to get other quotes and opinions. MGT Enterprise was definitely not the cheapest estimate I received but it was well worth the price. The owner, Shaun, informed me the quote was a ball park estimate but the price for whatever reason would not go up. He then called several places for all the materials to be hauled to and from for the best prices and shortest distance to save me as much money as possible. My final price was almost $3000 less than the price I was quoted. WOW! When choosing who to hire I looked for quality not quantity and they were the best. Everyone had great personalities and attitudes, very punctual and just all around a great team. Their honesty and integrity was very important to me. I will most definitely be calling them again."

FAQs for excavation projects in Erwin, TN

Depth depends on the type of installation and the regulations in your area. Water supply lines typically require 24 inches, while drainage pipes are often installed 36 inches below grade. For most general projects, a depth of 12 to 24 inches and a width of about eight inches is sufficient. Sticking to these specs keeps your utilities safe, code-compliant, and easier to maintain later.

When you need to run utilities underground, you’ve got two main options: boring or trenching. Boring employs directional drilling to install utilities without exposing a continuous channel, while trenching requires excavating an open channel to place utilities securely. Directional drilling preserves landscape integrity, whereas trenching provides direct access for installation, albeit with greater surface disruption. This clear comparison helps you select the method best suited to your project.

Plan on 12 hours to dig 100 linear feet when the soil is cooperative and you can work continuously. This timeframe applies when work is performed consistently and methodically. Factors such as rocky soil, tree roots, obstructions, and frozen ground increase the overall duration, demanding extra planning and effort. Comprehensive operational planning ensures that every challenge is managed efficiently and the project is completed on schedule.

If you want your yard to look untouched, laying fresh sod over the trench is the quickest fix. New sod needs 30 to 45 days to root and blend with the rest of your lawn. A local sod pro can provide you with a firm timeline and tips to ensure the grass takes hold and maintains your curb appeal.
