"Variant was fantastic through the entire project. From the first phone call during bids through the completion, you knew you were working with a real professional. Adam was communicative, insightful, and thorough. Through each phase we have had Adam out, his work has been well done and beautifully finished. His dedication to his customers goals is felt. I would happily recommend him to friends and family."

"Dillon Excavation just completed a grading and drain system project for me on my horse property, and his work was exemplary. He was conscientious, punctual, thorough, and knowledgeable. The final cost was exactly what he quoted, and he was a pleasure to work with. Dillon’s integrity is top notch, and I’d absolutely hire him again and again."

"Matt was very professional, efficient with his time, competitively priced, and amicable. He avoided many things that we discovered in the ground, even after private utility location. I would absolutely hire him again for future projects and would refer him to anyone needing an excavation operator with refined skills. Thanks, Matt! Five Stars!"

"Matt and his company did through and quality work. We couldn't have been happier with the end result. He went above and beyond to ensure we were happy with the work that was done. We had several bids and he was 1/3 of the cost the others were. But more importantly he stood behind the work he did and was a man of his word which is so hard to find. If you're struggling to find someone who is reliable and does quality work look no further. You won't be dissappointed"

Excavating questions, answered by experts

There is no standard depth for burying a septic tank; they are typically buried anywhere from 4 inches to 4 feet underground. The final depth depends on several factors, including the depth of your main sewer line, the height of the bedrock, soil type, local regulations, and the property's landscape. If you plan to grow grass or plants over the tank, a depth of at least 4 to 6 inches is recommended. Deeper tanks can be more difficult to locate, but a septic professional can help find it for you.

Downspouts should be buried at least 5 to 10 feet away from your foundation. This can vary depending on your local building codes, soil type, and property slope. The main goal is to ensure water is directed away from your foundation.

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.

Slab foundations are more affordable than crawl spaces because they require minimal excavation, as the slab sits directly on the ground or on footers that only sink a few feet into the ground. Crawl spaces require excavation of the entire footprint of the home to several feet below the surface. Not only does that mean higher labor costs, but more materials are necessary for the concrete foundation walls.

The physical constraints of hand-drilling a well limit the depth you can achieve. Manually digging with picks and shovels may only lead to shallow wells of up to 60 feet in depth. To reach greater depths, you need more specialized equipment. The diameter of your well and the tools you’re using will determine how far down you can dig.
