"We hired Eric's to build a large retaining wall; approximately 100 feet long and 6 feet tall. They completed the work promptly, everyone I spoke to was professional and punctual, and the quality of the work is excellent. Fair price and great workmanship; recommend."

"Jerid Strasheim and S4 Excavation are a top-notch professional operation. We had them regrade and install Geocells on our old gravel driveway. They explained the process and costs very clearly, arrived at the time promised, worked diligently and made sure we were fully satisfied with the job before leaving. We would definitely hire them again."

"This experience was the old time quality and service you hear your grandparents talk about. The crew showed up 15 minutes ahead of time ready to start. While a fairly non-complex job of removing existing material and leveling the sloping site with crushed gravel, all material removed was redistributed around the yard. The concrete work was carefully laid out, true and square. The finish completely uniform in spite of high winds blowing leaves into site. When they finished the job, the clean up was spotless. All debris was removed and the driveway and all adjacent concrete washed down. Several times during progress, I was consulted if they had a suggestion for improvement or question. Every one of the workers was courteous, polite and thanked us before leaving. Fast, efficient and cost effective."

"Daniel was awesome to work with. He came out and provided a solid estimate in a timely fashion. We had an unexpected sprinkler line that was in the middle of our excavation area and he took care of that. He also provided the materials for a retaining wall that we hadn't initially planned for, and he added that to the project scope without issue. I will definitely reach out to Daniel if we have another project like this one."

"I hired Paul to help me with multiple projects. He mowed our 2 acre field property when the grass was 4-5ft tall, which gave us easy access to our whole property. He regraded our driveway with approx 20yrds of gravel, leaving it smooth enough I could easily ride my street bike on it. He also excavated a small seasonal pond on our property and removed enough dirt to triple it in size, giving us a year round pond. Very happy with the results of all his work, worth every penny. I will be using Army of One again."

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. 

Most residential basements are 8 to 10 feet deep. You can dig deeper depending on building codes, but it does become more difficult. You’ll likely need to install stronger foundation walls and additional supports to handle the increased load. Depending on the water table, you may also need a water management system. Clay soil can support a deeper foundation than sandy soil. A structural engineer will be able to tell you the maximum, feasible depth.

It takes one hour to dig a 10-foot trench by hand. Use a trenching shovel with a sharp tip and a long head. Plan for more time if your soil is heavy or rocky. Consider renting a trencher if you’re digging a long or deep trench or if you have challenging soil or terrain. 

In most areas, you will need a permit for excavation work, even for projects that only involve grading or yard leveling. Permit requirements depend on your local government and the scope of the project, but they are especially common for significant digging or work that could affect utilities or public property. These permits help protect the local topography and prevent drainage issues. An experienced excavation company will typically know whether permits are needed and can often handle the process of pulling and closing them for you. You can also verify permit requirements by contacting your local building department and describing your project.

The rules for trenching and excavation include setting up and following safety protocols, learning how to use tools and machines properly, and ensuring there is a safe exit for all workers. Keep heavy equipment and materials away from the edge of the hole or trench. Call the 811 dig line before starting any excavation or trenching project to ensure you don’t hit any electrical or gas lines.
