"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."

Excavating questions, answered by experts

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.

In the United States, a depth of 36 inches (three feet) for underground water lines is the accepted industry standard. This depth varies from location to location based on local conditions. In areas with colder winters, they may be buried deeper to prevent frozen well water pipes : This is usually at least six inches below the frost level. The International Plumbing Code calls for a minimum of 12 inches below grade.

Most residential basements are 8 to 10 feet deep. You can dig deeper depending on building codes, but it does become more difficult. You’ll likely need to install stronger foundation walls and additional supports to handle the increased load. Depending on the water table, you may also need a water management system. Clay soil can support a deeper foundation than sandy soil. A structural engineer will be able to tell you the maximum, feasible depth.

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

Whether you grind or dig up and remove your tree stump depends on your landscaping goals. Using a stump grinder leaves the root system in place for it to decompose over time, whereas digging up the tree stump removes the roots and the stump. Overall, stump grinding is a far simpler process since you won’t need to deal with the roots. Stump removal will make your yard look like a demolition site, but you’ll have an easier time replanting in the same place as your former tree.
