"I hired Gary Gaston to clear my severely overgrown backyard. He showed up when he said he would to look at the job and give me a bid. I decided to go with Gaston Brothers and we set up a day and time to start the project. Gary said he could do it in one day. Again he showed up on time and started the work. I was impressed at Gary's skill operating the backhoe. That is truly a lost art. He cleared enough to fill 2 full sized dump trucks. Gary went the extra mile by leveling out the yard. It's ready for me to rake it smooth and plant grass. Thank you Gary!"

"Harry and crew did a fabulous job helping design and then building our retaining walls, at an appropriate price. They started exactly when scheduled and finished promptly a week later. Results are fabulous. I absolutely hope to work with them on future projects, and recommend them without reservation."

"Overall a good experience. We hired ACS to take down and rebuild a brick pillar supporting our front porch. Gary's crew was excellent. Although they only spoke Spanish they were helpful and did a good job communicating as much as they could about what they were doing and/or had done. We're very happy with the end product. Gary stayed true to his quote and the contract price. The project was more involved than I expected, but they came through and completed it on budget. My only complaint is that Gary was hard to get a hold of at times."

"They did an excellent job. They were on-time, fast and high quality work. Challenging job site with several large trees and massive roots. They moved a huge amount of dirt and did a precise leveling with proper drainage. They prepared the project in one day and poured the next! The stamping process was very interesting and a work of art. Several neighbors have talked to me about having them do work for them. Still getting complements!"

Excavating FAQs, answered by experts

Above ground pools are not buried in the ground. Typically, above ground pools are semi-permanent. One reason they’re more affordable is that you don’t have to dig for an inground pool and pour concrete or another material. However, you can choose to install a semi inground pool, which is a hybrid between the two.

It can take several weeks for the ground to settle after removing a tree, and the soil under larger, more mature trees can take months. The deeper the tree has been ground under the soil, the longer it will take to settle. However, this extra depth can help you plant new landscaping sooner because you’ll have more space for fresh soil.

Septic drain lines (or leach lines) are typically buried between 18 and 36 inches underground, and should be at least 6 inches below the surface. These pipes are perforated and surrounded by filtering materials like sand or gravel. Burying the lines at this depth helps minimize odors and allows bacteria and other biological processes in the soil to effectively treat the wastewater. Burying lines too close to the surface can cause issues unless the soil is very compact and stable.

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. 

Water lines are buried at various depths, depending on the type of line. For example, most sprinkler lines are buried between four and 12 inches underground. On the other hand, water mains usually sit between one and 3 feet below ground. However, they can go even deeper in cold climates to prevent freezing.
