Customers say: Quick response

"I really appreciated the great excavation and fill work that Roland Gagnon did for me. This was a driveway drainage project that required low spot filling and proper grading of the area. The driveway now has the proper slope and is draining properly. Roland went above and beyond my expectations, he will be my first call for any future work."

"I hired Matt to prepare a site for a shed we have ordered. He replied promptly for a request for an estimate. He explained what needed to be done and gave me a fixed date when he could do the work. Throughout the project, he kept me apprised of the progress and explained the choices that needed to be made. I was impressed with the care with which he approached every aspect of the project. Just a great guy to work with."

"We hired Waterscapes when our initial contractor abandoned the project and took our money, and they did a great job.  They were very communicative and sent regular status updates to us which we appreciated since we lived out of state.  Additionally, they finished the project in 10 days which was really impressive considering that they had to basically start from scratch  They also had competitive prices and cost-effective solutions to problems that satisfied all of our neighbors' concerns."

Excavating questions, answered by experts

You can bury underground electrical wire six inches deep—but only if you use a rigid metal electrical conduit. For rigid, non-metallic conduits, bury the wire at least 12 inches deep. If using an underground feeder cable rated for direct burial, you'll need to place it at least 18 inches deep, as it has no conduit for extra protection.

If you’re planning to dig on your property, you’ll need to check for underground utility lines. Call the national call-before-you-dig 811 number. Once connected to an operator, you can schedule a site visit to mark underground lines. This way, you won’t accidentally dig into pipes and can cause major (read: costly) issues.

Yes, professional installations include trenching or borehole drilling required for ground loops.

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.

You can dig 60 to 80 linear feet by hand per day depending on the depth. Digging a 100-foot trench by hand will take you two work days, but it can take longer if you have heavy or rocky soil. If you’re digging a deep trench or one that’s over 100 feet, consider renting a mechanical trencher, such as a walk-behind or ride-on, or calling a pro for help.
