"The attention to detail of the work was top rate. We had three sink holes in our yard that they took care of for us, as well as spreading loam for us to start a lawn in the spring. I very highly recommend McAdams Excavation."

Excavating questions, answered by experts

Slab foundations are more affordable than crawl spaces because they require minimal excavation, as the slab sits directly on the ground or on footers that only sink a few feet into the ground. Crawl spaces require excavation of the entire footprint of the home to several feet below the surface. Not only does that mean higher labor costs, but more materials are necessary for the concrete foundation walls.

There are several different factors that influence how long it takes to excavate. For a foundation, it could take anywhere from three days to three weeks. It can take even longer if you face weather-related delays or an inaccessible site that’s riddled with boulders and rough terrain. It may also take longer if you have clay soil, which is more difficult to dig.

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.

Most residential basements are 8 to 10 feet deep. You can dig deeper depending on building codes, but it does become more difficult. You’ll likely need to install stronger foundation walls and additional supports to handle the increased load. Depending on the water table, you may also need a water management system. Clay soil can support a deeper foundation than sandy soil. A structural engineer will be able to tell you the maximum, feasible depth.

Your contractor should handle dust control during the project. It's best to speak with your contractor beforehand to check if they plan to cover your furniture, protect your vents, or use fans to redirect dust. Eliminating drywall dust is a particularly large challenge during construction, so always take this into account during your planning phase.
