Site grading is the process of adjusting the slope and elevation of the soil around a home or building. Prior to construction or renovation, site grading may be performed to even out the surface and provide a solid foundation. For existing buildings, grading may be required to improve drainage and create the desired appearance for landscaping features.
Successful grading projects often require input from professional engineers or earthwork contractors. These individuals inspect the land to evaluate soil conditions and moisture problems. Geotechnical or civil engineers may also refer to local contour maps to learn more about elevation changes and how rainwater reaches local water bodies. Based on the advice from these professionals, homeowners to earthwork contractors can regrade the property as needed.
One of the primary concerns of site grading is to control the flow of storm water. Left uncontrolled, storm water may collect around the foundations of a building, leading to rot or safety issues. Excess moisture within the soil can also impact the ability of plants to grow, and can lead to a spongy or marshy soil texture.
When site grading, bulldozers are often used to remove or redistribute dirt.
