Excavating questions, answered by experts

A perc test takes an average of around two hours, but it can range from one hour up to around six hours. Perc tests that require wider or deeper holes and those that require multiple holes dug throughout your property will take longer because there’s more excavation involved. The actual filling of the hole and monitoring to gauge the rate of percolation should take under an hour per hole.

A mini excavator can dig between 5 and 11 feet deep, depending on the type and size of the mini excavator. Mini hydraulic excavators are more powerful and can reach deeper into the earth, but electric models have a more limited range. Mini excavators over two tons in size are also more powerful and able to dig as deep as 11 feet.

You can dig 60 to 80 linear feet by hand per day depending on the depth. Digging a 100-foot trench by hand will take you two work days, but it can take longer if you have heavy or rocky soil. If you’re digging a deep trench or one that’s over 100 feet, consider renting a mechanical trencher, such as a walk-behind or ride-on, or calling a pro for help. 

Trenches are 12 to 24 inches deep and 8 inches wide. However, the right depth for your trench will depend on the nature of your project. For example, if you’re digging a trench as part of a French drain installation, it should be 18 inches deep. An excavation professional can explain how deep your trench should be.

A walk-behind trencher can cut through roots as long as they’re not too thick, making a project much easier than digging with a shovel and other hand tools. Assess your terrain and the number of trees in the surrounding area to determine if a walk-behind trencher will ease the job. Digging a trench by hand is much more time-consuming and labor-intensive.
