Excavating questions, answered by experts

Yes, you can install a trench drain if you already have concrete in your yard or garden. While it can complicate some aspects of the job and slightly run up the cost, it is doable. Residential trench drains can be easily retrofitted to outdoor areas with concrete without having to remove excessive amounts of your patio, pool area, or decorative walkways.

Yes, trenchers can go through gravel. Gravel is made up of smaller, softer rocks that certain trenchers are able to cut through. Just be sure to use a rock wheel trencher or chain trencher, both of which are made to cut through rocky landscapes and gravel pathways without dulling the teeth or chain.

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.

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.

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.
