Excavating questions, answered by experts

Excavations take a few days or up to a few weeks. The time it takes to excavate an area depends on the size of the area, the type of soil, the type of excavator, and even the time of year, since winter can make digging up the ground more difficult.

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.

You should dig 3 to 6 inches deep for plastic edging. Dig as wide as you need to fit your plastic edging into it—2 inches is usually sufficient.

There are many ways to cut through roots when digging, especially if your trencher doesn’t seem to be removing the roots. First, use a shovel to expose the roots. Then, use gardening shears to clear out smaller roots or a reciprocating saw to remove larger plant roots. If you plan on keeping the plant, avoid cutting any roots over 2 inches thick.

Professional installers often include a deep layer of crushed gravel under permeable pavers to allow more runoff to soak through into the soil below. Many installations will include multiple layers of gravel, with coarser aggregate at the base and finer aggregate that sits on top of that bottom layer. Above the gravel, you’ll often find coarse sand that helps reduce paver shifting over time. Some permeable paver designs include a water collection system set into the gravel layer to route runoff to a safe area for disposal.
