"Anthony was very professional and clear on what was going to take place. Anthony and his crew arrived on schedule and completed the replacement of the broken sewer main in one day. No mess was left, grounds were smoothed out and ready for new lawn! Anthony's wife is very nice to talk to and takes care of any communication needed. My husband and I would highly recommend this company."

"This was the best landscape design experience I could have ever imagined. They were prompt, professional, and committed. Provided a creative draft of the project, took time to consider my thoughts and ideas, they were very knowledgeable of the plants and trees in the area and what would be the best for my project and property. They had professional assistance to preform the work. The materials they used were quality and the finish project came out just like I expected. Actually even better."

Excavating FAQs, answered by experts

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

There is no standard depth for burying a septic tank; they are typically buried anywhere from 4 inches to 4 feet underground. The final depth depends on several factors, including the depth of your main sewer line, the height of the bedrock, soil type, local regulations, and the property's landscape. If you plan to grow grass or plants over the tank, a depth of at least 4 to 6 inches is recommended. Deeper tanks can be more difficult to locate, but a septic professional can help find it for you.

A perc test can take anywhere from one to eight hours to complete. The total time depends on factors like the amount of excavation required, the depth and width of the holes, and whether multiple test holes are needed. For a single hole, the process of filling it with water and monitoring the drainage rate usually takes less than an hour. Professionals can often complete the entire test in a single day. While it's possible to get results the same day, some companies may take a few days to provide the official report.

The rules for trenching and excavation include setting up and following safety protocols, learning how to use tools and machines properly, and ensuring there is a safe exit for all workers. Keep heavy equipment and materials away from the edge of the hole or trench. Call the 811 dig line before starting any excavation or trenching project to ensure you don’t hit any electrical or gas lines.

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.
