Excavating FAQs, answered by experts

Whether you grind or dig up and remove your tree stump depends on your landscaping goals. Using a stump grinder leaves the root system in place for it to decompose over time, whereas digging up the tree stump removes the roots and the stump. Overall, stump grinding is a far simpler process since you won’t need to deal with the roots. Stump removal will make your yard look like a demolition site, but you’ll have an easier time replanting in the same place as your former tree.

It takes one hour to dig a 10-foot trench by hand. Use a trenching shovel with a sharp tip and a long head. Plan for more time if your soil is heavy or rocky. Consider renting a trencher if you’re digging a long or deep trench or if you have challenging soil or terrain. 

You do not have to dig footers for a deck as long as it meets local code and holds up to weather in your area. If you live somewhere that experiences high winds and earthquakes, you may need to dig for your deck posts. Deck blocks, post anchors with base plates, and helical pile systems are the three no-dig deck post options you can choose from if local code permits.

Yes, professional installations include trenching or borehole drilling required for ground loops.

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.
