Groundwater Assessment & Monitoring
Groundwater assessment and monitoring provide essential data for construction projects, environmental management, and infrastructure development.
Atlas Engineering and Technology Group (AETG) specialises in total groundwater management, providing the hydrogeological knowledge base essential for successful project implementation.
Groundwater Assessment Importance
Groundwater conditions can greatly affect construction projects and existing structures in various ways:
- Basement construction may encounter groundwater, requiring specialised design and waterproofing
- Groundwater uplift pressure can damage foundations and floor slabs
- Fluctuating water tables can affect soil stability and bearing capacity
- Contaminated groundwater may pose environmental and health risks
- Dewatering activities during construction require proper planning and monitoring

✔ Proposed Residential Development - Noorong Avenue, Frenchs Forest NSW
The geotechnical investigation at Noorong Avenue, Frenchs Forest identified groundwater seepage at a depth of approximately 0.9 m below ground level in borehole BH02, while no groundwater was encountered in BH01. This suggests that shallow groundwater may be present intermittently across the site. The report highlights the potential for groundwater inflow during excavation, particularly if additional footings are introduced. It recommends that dewatering methods—specifically sump pumping—be employed during construction if seepage is encountered. The presence of groundwater, although localised, underscores the importance of proactive water management measures during the development phase to prevent construction delays or foundation issues.
✔ Proposed Residential Development - Coal Pier Road, Banksmeadow NSW
The geotechnical investigation conducted at Coal Pier Road, Banksmeadow, did not encounter any standing groundwater or seepage within the three boreholes drilled to a depth of 2.0 m below ground level. However, a cement-stabilised fill layer was present beneath the recycled material, requiring the use of drilling fluid to advance the boreholes. While this may suggest relatively low permeability, the report cautions that rainfall or surface water runoff could migrate horizontally along this stabilised layer during remediation activities. Such movement could lead to oversaturation of the surrounding pavement base material, especially near defect perimeters, potentially compromising adjacent intact pavement areas. Therefore, it is recommended that all pavement remediation works be conducted during dry weather conditions and completed the same day to mitigate the risk of water ingress and associated structural degradation.
