Excavating questions, answered by experts

Most residential basements are 8 to 10 feet deep. You can dig deeper depending on building codes, but it does become more difficult. You’ll likely need to install stronger foundation walls and additional supports to handle the increased load. Depending on the water table, you may also need a water management system. Clay soil can support a deeper foundation than sandy soil. A structural engineer will be able to tell you the maximum, feasible depth.

To locate an underground downspout, you should start by identifying where the above ground gutter drains. Look for an entry point, such as a pipe or elbow leading into the ground. Follow the surface path for signs like depressions, landscaping disruptions, or wet areas after rain. You can use a metal detector or plumber’s snake to trace the pipe underground. For deeper pipes, a professional locator tool or camera inspection may be necessary. Visual markers or utility maps can also guide the search.

Preparation involves site assessment, clearing debris, grading surfaces, and compacting soil to support stable construction.

Prior to excavation, you should prepare the dig site and call 311 before you sign anything.

To get your site ready for excavation, you should move anything in the area that isn’t affixed to the land. You can save money on the excavation by removing hardscaping, including walkways, decks, concrete patios, and paver patios.

Before you carry out any digging, you should call 311 to confirm that there are no utility lines running through your excavation site. Skipping this step could lead to severe injury and property damage if your excavator hits a water, sewage, or gas line.

Chipmunks dig their burrows about three feet deep and up to 30 feet long. The entrances can be two inches wide or more. Chipmunks are fiercely protective of their burrows and use them to protect the nuts and seeds they gather for the long winters.
