"Really easy to communicate with. Was able to come give an estimate and schedule work right away, which is amazing bc majority of the local excavation companies are being contracted to work the wildfires. He was helpful with decision-making and did extra things outside the scope of job expectation. Will definitely use this company again."

Excavating questions, answered by experts

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.

Above ground pools are not buried in the ground. Typically, above ground pools are semi-permanent. One reason they’re more affordable is that you don’t have to dig for an inground pool and pour concrete or another material. However, you can choose to install a semi inground pool, which is a hybrid between the two.

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.

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.

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.
