"Called for a estimate to repair a private rd with two houses on it. He came out in a timely matter and took the time to share what would be the best solution based on his experience. We hired him to build up and grate the driveway/private rd. He showed up during the time frame he said he would and built up and graded the driveway/private rd as well as pitched it so that water wouldnâ t pool. He is just a great guy with a ton of experience to help the customer make the best informed decision. Will use Faulkner for any needs we have in the future hands down."

Excavating questions, answered by experts

Trenches are typically 12 to 24 inches deep and 8 inches wide. However, the required depth depends on the specific project and local ordinances. For example, a French drain may need to be 18 inches deep, while a water pipe might require a depth of 24 inches and a drainage pipe 36 inches. Your city or county may have specific regulations, so it's wise to consult with an excavation professional to determine the correct depth for your project.

Call 811 to locate and mark the gas lines at least three days before digging. In many areas, you can dig within 18 inches of the lines, though in some locations, the distance may be further. Check local regulations, as you may need a utility company representative onsite when digging. Document your calls to 811 and precautions taken to avoid gas lines. A homeowner can be held liable for hitting a gas line in some cases, but contacting the proper authorities and following all guidelines can offer protection.

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.

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.

A joint utility trench, or joint trench, is a long, buried ditch on a property that contains two or more utility lines rather than running the lines in multiple trenches. Some utilities, like gas and electric or electric and communication lines, are better suited to joint trenching, while others, like water and sewer, are not allowed to be in the same trench.
