"Had a backup a few days before and wanted to determine if it was a simple clog or cesspool related. They sent out a tech (Jimmy) the same day. He located both cesspools and walked me through my options. He was honest and patient, answering all my questions along the way."

"What started as a simple top soil delivery ended as a new driveway install. Initially, my husband hired Sean of Limitless Landworks to deliver some top soil. He made such a positive impression on us that we decided to have him install a much needed new gravel driveway. From the initial excavation to the final laying of the gravel, everything was handled professionally, the service was exceptional, and the final product was better than we could have imagined. Sean is very knowledgeable, a hard worker, has impeccable attention to detail, is an excellent communicator and a super nice guy! We couldn’t have been more pleased with our experience!"

"Although I do you use HomeAdvisor I must admit that this company came to us by recommendation of our neighbors. We moved in October 2019 with many difficult lawn issues and landscape issues to deal with. They have been honest andHave a wonderful friendly staff. They also consistently cut our lawn every week and are always pruning and tending to our garden as well., and itâ s beautiful. Good local find and we intend to keep them. What I also like about this company is that the owner, Santos, is always on site every week directing his staff and listening to any issues that we may have at that point."

Excavating questions, answered by experts

Septic drain lines (or leach lines) are typically buried between 18 and 36 inches underground, and should be at least 6 inches below the surface. These pipes are perforated and surrounded by filtering materials like sand or gravel. Burying the lines at this depth helps minimize odors and allows bacteria and other biological processes in the soil to effectively treat the wastewater. Burying lines too close to the surface can cause issues unless the soil is very compact and stable.

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.

Call 811 to locate and mark the gas lines at least three days before digging. In many areas, you can dig within 18 inches of the lines, though in some locations, the distance may be further. Check local regulations, as you may need a utility company representative onsite when digging. Document your calls to 811 and precautions taken to avoid gas lines. A homeowner can be held liable for hitting a gas line in some cases, but contacting the proper authorities and following all guidelines can offer protection.

Directional drilling is complex and requires training to use the advanced machinery. It can be challenging to monitor the position of the drill since there’s no direct line of sight. Directional drilling can also be more expensive with a cost of $10 to $30 per linear foot compared to $5 to $12 per linear foot for trenching.
