"AP Excavating installed a drinking post for our horses and replaced a water hydrant. Wonderful father and sons family business - great to work with them and their crew. I was impressed with the quality of work and their commitment to making sure they exceeded our expectations. I will be using them for our next projects: entry gate, trenching work and landscaping driveway island. Thank you AP Excavating!"

"Rich Che and the CNS Empire Landscape crew did fabulous improvements on our family home in Wheat Ridge. They corrected drainage on three sides of an addition so water flows away from the house instead of into the crawlspace; replaced 30 feet of exit pipe from the perimeter drain around the foundation of the addition; installed new sod; and removed weeds from landscaped rock areas in the front yard. The improvements look great. Shortly afterwards, I engaged an inspector to check the foundation. The inspector said he visits about 400 houses each year, and this drainage remediation is among the best he’s seen."

"Tanner and his crew were professional and thorough. They took care to minimize the impact of having a small loader in my yard, and rehung the gate to the back yard better than it was before. Well done and would recommend."

"Steve was so wonderful to work with. We needed someone to excavate and grade our side yard in preparation for laying gravel. He was very timely in getting us scheduled and his work was very well done. Overall, Steve was a clear communicator, gave a fair price, and took care to ensure we were happy with the results of his work. I would highly recommend him!"

Excavating questions, answered by experts

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.

Yes, you can technically make a crawl space liveable, but the only way to do so is by converting it into a basement. While some crawl spaces are big enough to walk through and store large items, they lack appropriate insulation and space to be liveable.

Trenching is a specific kind of digging. Trenching means digging a depression in the earth that’s deeper than it is wide, often with heavy machinery. Digging refers to any kind of removal of earth in order to create a human-made depression, hole, or cut in the earth’s surface. You can dig with big tools or even with just a hand shovel.

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.

Excavation and grading are both generally necessary for designing your foundation, and leveling the ground where your foundation will go. These steps can also prepare the area by removing vegetation and anything else that could interfere with your home’s foundation.
