Common excavation situations include ground that needs lowering, uneven areas that need reshaping, material that must be removed before a driveway can be constructed, or trenches and surrounding areas that need opening for drainage works. Excavation is also closely connected to site cuts, where larger areas of ground need to be brought to the required profile or level. On sloping sites or anywhere substantial level changes are being made, retaining walls may need to be considered as part of the broader project. Water is another important factor. Once ground is excavated, existing runoff patterns can change, which is why drainage needs to be thought about before the finished landscaping, concrete or asphalt goes in. Access also affects how excavation is approached, particularly where machinery needs to work around existing structures or established sections of a property. Advanced Earthworks and Drainage carries out excavation and associated earthworks across Clyde North, Cockatoo, Emerald, Koo Wee Rup and surrounding areas.
