"Ken, is awesome! He is friendly, easy to talk to, and will take care of all your needs. I hired Ken to excavate my front lawn for landscaping. He and his professional helper/excavator, Gearmo, took measurements of my front, backyard and determined the grade of my front lawn using a laser to match the grade of my residential street in front of my house. Ken, also removed some stumps in my backyard, did some grading around my septic tanks, and moved my tough shed in my backyard. Ken prices are good, you definitely get what you pay for. I most definitely would use Tannahill Construction LLC for my excavation needs and recommend him to anyone. My yard and house look amazing, thanks to both of you. Take care and God bless!"

"Perfect! Very professional estimator & project manager and the work crew was fantastic. Worked 7 days straight, very punctual and extremely tidy. They consulted with me whenever they had a question or to clarify something to make sure it was exactly how I wanted it. Very high quality- I plan to hire them again in the future to do front yard project with pathways & terracing."

Excavating questions, answered by experts

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. 

Professional installers often include a deep layer of crushed gravel under permeable pavers to allow more runoff to soak through into the soil below. Many installations will include multiple layers of gravel, with coarser aggregate at the base and finer aggregate that sits on top of that bottom layer. Above the gravel, you’ll often find coarse sand that helps reduce paver shifting over time. Some permeable paver designs include a water collection system set into the gravel layer to route runoff to a safe area for disposal.

Digging a well can cost between $20 and $25,000, depending on your needs. If you’re looking to dig a well yourself, all you need is a shovel. If you’re looking to have a well drilled by a professional, you can expect to pay around $15 to $30 per foot. The total cost of drilling a well will average to $5,500.

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.

Skunk digging looks like a series of small, cone-shaped holes on a lawn or around the perimeter of a home, porch, deck, or shed. The holes that skunks dig when searching for grubs tend to be no more than four inches in diameter and may be up to four inches deep.
