Excavating questions, answered by experts

It all depends on the scope of the project. A trencher can certainly save time and energy, but you might not need to dig that deep in the first place. Aside from the depth of the trench, the quality of the soil matters. If it’s light, soft soil, you might try a shovel first. However, if the soil is rocky and hard or there are obstructions in it, like tree roots, a machine trencher might be the better option.

Tree experts don’t advise against digging through tree roots, but instead encourage caution and consultation with a local arborist to make sure you don’t damage the tree’s structure or interrupt its water or nutrient intake. An arborist can recommend specific practices when digging and help prune the roots or dig a trench for utilities with a tool that can remove soil without touching the tree’s roots.

Septic tanks are typically buried between four inches and four feet deep, depending on the property, the soil, and the size of the tank. When the septic tank is buried on the deeper end of this range, it may be harder for you to locate it on your own with a soil probe or just by observing the yard for signs of the tank. However, if you have trouble finding the septic tank, a pro will be happy to help you.

It is a common belief that excavation is easier or less costly when done in the summer or when the ground is not frozen. Seasons have little effect on when excavation can occur; however, inclement weather can prolong the duration of the job and potentially increase costs. For this reason, those in rainy climates may opt for seasons with milder weather.

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.
