"I hired Brad Riddle to do a clearing , hauling, ground prep and laying rocks job . The front yard area was massively overgrown and several sections needed to be addressed. Brad was cooperative, helpful and had to work around my unusual schedule, my grandkids schedules and then rain delays. This took a number of months to coordinate.! We are all pleased with the clean results, and Brad has agreed to return to assist with locating the irrigation lines in order to add some plants. I would highly recommend Brad for his hard work, flexibility and collaborative efforts!"

"We thoroughly enjoyed working with this company for our turf repair project. They got us in weeks ahead of schedule as they knew time was an issue for our busy daycare. They came up with a plan to fix the seams and clumping issues in our turf that we just had installed by another company. They made the most of a tough project and were able to provide us with a playground surface our littles will be able to use for years to come. The guys are fun to work with and Dawn is a problem solver. I can’t recommend them enough."

Excavating questions, answered by experts

A joint utility trench, or joint trench, is a long, buried ditch on a property that contains two or more utility lines rather than running the lines in multiple trenches. Some utilities, like gas and electric or electric and communication lines, are better suited to joint trenching, while others, like water and sewer, are not allowed to be in the same trench.

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.

Excavations take a few days or up to a few weeks. The time it takes to excavate an area depends on the size of the area, the type of soil, the type of excavator, and even the time of year, since winter can make digging up the ground more difficult.

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.

Depth is not a qualifying component of evacuation. Any human-made cut, cavity, or depression in the earth’s surface is considered excavation. The hole from excavation can be any size, shape, or depth. Excavation is used to create foundations, reservoirs, drainage ditches, and roads. Long, narrow excavations are called trenches and are often used for underground utilities.
