Excavation and site cuts are useful where existing levels need significant adjustment or ground must be prepared before another stage can begin. Drainage may be required where water collects or runoff needs to be managed around altered levels. On driveway projects, excavation and preparation come before the finished surface, with concreting or asphalting available depending on the project. Retaining walls can form an important part of these works when excavation or landscaping creates different ground heights. Landscaping itself can require considerable groundwork where an existing area needs reshaping before the finished outdoor space is created. These services are often closely connected. For example, excavating for a driveway without considering the surrounding drainage can leave water travelling across the new access, while landscaping a change in level may require retaining work to make the area practical. Similar projects are undertaken through nearby Emerald and Gembrook as part of Advanced Earthworks and Drainage's wider service area.
