Excavating FAQs, answered by experts

Dumpsters work best on hard, study, and level surfaces made of asphalt, stone, or concrete. If the surface is uneven or too soft, the dumpster could get stuck or tip over when filled. Keep in mind that you must obtain a dumpster permit to keep it on a city street in many areas.

A trench that is less than 5 feet deep often doesn't require a protective system. Most residential trenches will not go this deep (the typical residential drainage trench is just 18 inches deep). In the event that an excavator needs to dig more than 5 feet beneath the surface, a protective system is required unless the excavation is in entirely stable rock.

Yes, chipmunk holes may have two or more entrances. Chipmunks can create an entire network of burrows. Having multiple entrances makes it easier for them when trying to escape from a predator, such as a snake, or if an entrance collapses due to flooding. Each entrance leads to the nesting chamber underground, which is where the chipmunk spends the majority of its time sleeping.

The easier way to find buried sprinkler lines is to use the plan from the professionals who installed the system. If you don’t have professional plans, listen for running water on your lawn when you turn on the system. You may also spot wet areas, giving you an idea of where the heads are. Once you find the sprinkler heads, you’ll likely be able to connect the dots between them, revealing the system below.

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.
