"Quality work. I had mulch from a couple tree trunks that needed to be taken off and top soil needed to be replaced and packed. I also had soil erosion near my sidewalk that needed extra top soil replaced and packed. They did what I asked and went an extra step with adding black top soil for the nutrients and seeded both places and put straw down to allow it to grow. They also said that if something happened and there was a problem with it that their work was guaranteed. They are a top notch landscaping company in my book and would highly recommend them."

"I have never felt so comfortable working with any other company I have ever hired for any kind of work. Fantastic people, honest, great work. We will hire BCB anytime we need excavating or land maintenance work. As a previous reviewer; we met them on-site of our land to go over the plans. A couple months later Cassie called us. They sent pictures each day of the work and we live 700 miles away. Looking forward to a long relationship."

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. 

Sewer lines can be buried anywhere from 18 inches to 8 feet deep, with a common average depth between 18 and 30 inches. The exact depth depends on local factors like climate and soil type. In colder regions, pipes must be buried deeper (below the frost line) to prevent freezing, sometimes as deep as 8 feet. The digging depth can also impact the cost of sewer line replacement. To find the specific depth for your property, you can check the building plans for your system, which should be on file with your city or local sanitation department since permits are required for installation.

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.

Trenching and boring are two distinct methods for installing underground utilities. Trenching involves digging a channel using equipment like an excavator, trencher, backhoe, or shovel. While it is a simpler process, it causes significant disruption to the surface, landscaping, and surrounding ecosystems.

Boring, also known as directional boring, is a less invasive alternative that uses a drill to create a tunnel for utility lines without disturbing the surface. This method is more precise and is ideal for installations that need to go underneath buildings, roads, or bodies of water. Although boring is less disruptive, it is generally more expensive than trenching.

You can dig 60 to 80 linear feet by hand per day depending on the depth. Digging a 100-foot trench by hand will take you two work days, but it can take longer if you have heavy or rocky soil. If you’re digging a deep trench or one that’s over 100 feet, consider renting a mechanical trencher, such as a walk-behind or ride-on, or calling a pro for help.
