Geotechnical services and ground conditions in Wollongong & Illawarra
Wollongong and the Illawarra include coastal and alluvial soils, residual clay, sandstone and other variable ground profiles, with steep escarpment terrain or local mining history relevant to some sites. Development may raise specific questions about slopes, retaining walls, excavation, fill, groundwater, on-site wastewater or stormwater infiltration. These issues require site-specific assessment; neither a regional description nor the proximity of the escarpment determines the conditions at a particular property.
