Excavating questions, answered by experts

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.

A perc test takes an average of around two hours, but it can range from one hour up to around six hours. Perc tests that require wider or deeper holes and those that require multiple holes dug throughout your property will take longer because there’s more excavation involved. The actual filling of the hole and monitoring to gauge the rate of percolation should take under an hour per hole.

Trenches are typically 12 inches to 24 inches deep and 8 inches wide. However, your city or county may have specific ordinances that clarify the dimensions needed for the project. For instance, a water pipe may need to be 24 inches deep, but a drainage pipe may need to be 36 inches deep.

The cost to drill a well ranges, but for a well that’s roughly 150 feet deep, you could spend approximately $5,500. However, prices can fluctuate substantially due to factors like geological conditions, local regulations, and variations in drilling methods. For a more precise quote tailored to your location, research local well-drilling professionals in your area.

Excavation and grading are both generally necessary for designing your foundation, and leveling the ground where your foundation will go. These steps can also prepare the area by removing vegetation and anything else that could interfere with your home’s foundation.
