Excavating FAQs, answered by experts

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.

The best method for digging a trench depends on the scope of the project. For a short, shallow trench (less than 2 feet deep) in light, soft soil, digging by hand may be sufficient. However, digging by hand is labor-intensive, so consider the effort required. A machine trencher is the better option for longer trenches (over 100 feet), deeper ones, or when dealing with difficult soil conditions, such as rocky or hard ground, or obstructions like tree roots. A machine can save significant time and energy in these situations.

Water lines are buried at various depths, depending on the type of line. For example, most sprinkler lines are buried between four and 12 inches underground. On the other hand, water mains usually sit between one and 3 feet below ground. However, they can go even deeper in cold climates to prevent freezing.

Almost any kind of home can have a wine cellar or cabinet installed. You’ll need an area where a concrete floor can be put in, along with the necessary insulation, climate control, and ventilation systems. If you think of yourself as an aspiring sommelier, an underground wine cellar may be ideal, but it will cost significantly more. 

What you choose to install really depends on your budget and how many bottles you’re looking to store.

To locate an underground downspout, you should start by identifying where the above ground gutter drains. Look for an entry point, such as a pipe or elbow leading into the ground. Follow the surface path for signs like depressions, landscaping disruptions, or wet areas after rain. You can use a metal detector or plumber’s snake to trace the pipe underground. For deeper pipes, a professional locator tool or camera inspection may be necessary. Visual markers or utility maps can also guide the search.
