A site cut is generally required when existing ground is too high, uneven or unsuitable for the planned works. The excavation process removes material to establish the required profile, while earthmoving may also be needed to reshape surrounding areas or manage excavated material. Practical considerations include machinery access, the volume of ground being moved, existing site conditions and how the new levels will affect water movement. Where a cut creates a substantial difference between levels, retaining walls may become part of the broader project. Drainage is another important consideration because reshaping a property can change where runoff travels and where water collects. On driveway projects, a site cut may form the first stage before ground preparation, drainage and the eventual concrete or asphalt surface. Landscaping projects can similarly require substantial excavation before usable outdoor levels are established. Advanced Earthworks and Drainage undertakes this type of connected groundwork throughout Nar Nar Goon, Koo Wee Rup, Cockatoo and Emerald.
