New South Wales Soil Challenges We Handle
Hawkesbury Sandstone: North Shore, Northern Beaches, Eastern Suburbs. Variable weathering from excellent fresh rock to weak weathered zones. Shallow bedrock with excellent bearing where sound.
Reactive Clay Soils: Western Sydney (Blacktown, Penrith, Camden, Liverpool). Expansive shale-derived clays with high plasticity, similar to Melbourne's western suburbs.
Coastal Sandy Soils: Beaches and coastal areas with lower bearing capacity, salt exposure, and erosion control requirements.
Alluvial Soils: Hunter Valley, Riverina, coastal plains. River-deposited soils with high water tables.
Coal Mining Legacy: Newcastle, Maitland, Lithgow areas. Subsidence risk, unknown fills, variable ground conditions from historic mining.
