Excavating questions, answered by experts

The best way to protect tree roots is to avoid the roots entirely by excavating outside the root radius of the tree. For nearby projects, it’s a good idea to construct a temporary retaining wall. But that’s not always possible, depending on the project and the root system. In these cases, consider using alternative equipment like an auger to tunnel under the ground.

Remember, tree roots can damage nearby cement foundations as they grow. If a tree is close enough to interfere with large excavations, it may be better to remove the tree than risk future problems.

Trenching is a specific kind of digging. Trenching means digging a depression in the earth that’s deeper than it is wide, often with heavy machinery. Digging refers to any kind of removal of earth in order to create a human-made depression, hole, or cut in the earth’s surface. You can dig with big tools or even with just a hand shovel.

Most states do not require excavation companies to hold specific licenses, but many require at least a contractor’s license. Additionally, heavy equipment operators require a special commercial equipment license to operate machinery required for excavation. You can use Angi’s contractor licensing tool to confirm that an excavation company you’re considering hiring is fully licensed. You should also make sure that the excavation team is fully insured before allowing them to work on your property.

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.

Yes, you can excavate in the winter, but it might make the job harder. Frozen ground is harder to dig, and snow or ice can make the work site more hazardous. A contractor may need special equipment and techniques, such as ground-thawing methods, to break through frozen soil. Although winter excavation is possible, it may take longer and be more costly than excavating during warmer months.
