"These guys were prompt, courteous, knowledgeable and skilled. â True professionalsâ showed up when they said they would for an emergency gas line repair excavation. They did not cause any unnecessary yard damage and even seamlessly replaced the grass where they dug. Top notch service and I would highly recommend!!!"

"Larry did an excellent job filling in my pool and grading the hillside to make it look seamless. He hydroseeded and now you can never tell a pool was there. He graded the yard and hillside beautifully for good drainage."

Excavating questions, answered by experts

Preparation involves site assessment, clearing debris, grading surfaces, and compacting soil to support stable construction.

No, a ditch isn’t a trench. A ditch is an open, relatively shallow channel that’s carved out of the ground and used for drainage purposes. In contrast, a trench is a deeper excavation that’s entirely underground. Trenches have many uses, including gas lines, sewage systems, and electrical wiring. Unlike trenches, ditches don’t get filled back in with dirt after they’re dug.

How deep your septic system needs to be into the ground depends on several factors. In extremely cold environments, the tank needs to rest below the maximum frost line, which can be up to six or eight feet deep. The standard burying depth for most systems is between a few inches and four feet below ground level. Depth can also depend on the slope of the landscaping and other property variables. 

The time it takes to build a pool—and dig out the area—varies based on the pool size and type. A professional excavator will take between four and eight hours to dig a pool. The process will take longer if they encounter large boulders or tree roots. Keep in mind that this is a small part of the process in the long run. You will need between eight and 12 weeks to build a pool from start to finish, including the time to apply for permits.

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.
