Geotechnical services and ground conditions in Blue Mountains
Blue Mountains projects can involve sandstone bedrock, variable weathering, shallow soil, local clay or fill, steep terrain and changes in surface drainage. A proposed house, addition, excavation or retaining wall may therefore raise different questions from a typical flat-site residential classification. Sandstone depth, weathering, fracture patterns, slope geometry, groundwater seepage and existing cut or fill vary between individual properties. Published geological mapping and neighbouring reports can inform the investigation brief but cannot establish the founding conditions or stability of a particular building footprint.
