"Our project they performed for us was a takedown of an an old existing wood retaining wall and installing a new concrete block wall and steps. Fantastic design and building around 100 feet of wall and steps. They insured that there was proper drainage by installing good drain material behind the wall so no buckling of it could ever occur and good drain outlets were installed. It looks great and we have had many compliments on it and their work. We would not hesitate to call them on other projects we might need."

"I used Diamond D to clear some land in Lakeport. Made a contact through HomeAdvisor. Tyler was super responsive, worked with me to define our needs and provided a clear bid. Both Tyler and Megan were very professional and communicated well with me since I live a few hundred miles away. I will use them again, it was a very good experience."

Excavating FAQs, answered by experts

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. 

No, you typically cannot use metal detectors to find your sewer line. Most sewer lines are made of non-metallic materials such as PVC, clay, or cast iron, which are not detectable by standard metal detectors. Metal detectors are designed to locate metallic objects, so they won't be effective for identifying the path of a non-metallic sewer line. To locate your sewer line accurately, it's best to use other methods.

As a general rule, the protected area should be about 1½ times as wide as the canopy of the tree’s leaves. This digging measurement can vary by tree species and the age of the tree. Of course, that can be a lot of fencing for larger trees, which is why our first step is about making difficult decisions on which trees to save.

Depth is not a qualifying component of evacuation. Any human-made cut, cavity, or depression in the earth’s surface is considered excavation. The hole from excavation can be any size, shape, or depth. Excavation is used to create foundations, reservoirs, drainage ditches, and roads. Long, narrow excavations are called trenches and are often used for underground utilities.

In most areas, you will need a permit for excavation work, even for projects that only involve grading or yard leveling. Permit requirements depend on your local government and the scope of the project, but they are especially common for significant digging or work that could affect utilities or public property. These permits help protect the local topography and prevent drainage issues. An experienced excavation company will typically know whether permits are needed and can often handle the process of pulling and closing them for you. You can also verify permit requirements by contacting your local building department and describing your project.
