"We had the worst weather possible for clearing trees, excavating, installing drainage, and prepping for a barn build on two and half acres, but Dave stuck with it and delivered the project as we had discussed. He provided updates regularly, and communicated well when issues arose by providing options that helped to stay on budget."

"Mike was great. I got two spots in my backyard that I wanted patio pavers, around one side of the pool and underneath my second floor deck. By the pool was approx. 250sqft with a walkway and below the deck 256sqft as well. Along with 3ft x 15ft concrete patch. I needed this project competed before the weekend and him and his crew was able to get the job in three days. Both patios look great and my wife can finally see my vision and she loves it as well."

Excavating FAQs, answered by experts

Drilled wells have a pipe sticking up that’s covered in a plastic or metal casing. On the other hand, a dug well will look like a big hole in the ground and is more similar to what you’d see in a fantasy or Western movie. If you want to be sure, contact the city for documentation on your property’s construction and excavation history. 

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.

Digging out a basement takes anywhere from a few days to a few months. Most projects take at least two to five weeks, but it could take several months if you encounter obstacles. This project takes longer if you need to brace or raise your home before the excavation. Digging out a basement in new construction can take as little as three days.

There are many ways to cut through roots when digging, especially if your trencher doesn’t seem to be removing the roots. First, use a shovel to expose the roots. Then, use gardening shears to clear out smaller roots or a reciprocating saw to remove larger plant roots. If you plan on keeping the plant, avoid cutting any roots over 2 inches thick.

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.
