Wingecarribee and Wollondilly councils
The Highlands sit on Wianamatta shale and Hawkesbury sandstone, with basalt caps around Robertson and Bowral weathering to deep red clays. Larger rural-residential blocks, new estates around Moss Vale and knock-down rebuilds in the towns are the typical jobs, and reactive clay is common.
In the ground
These are the patterns a field engineer expects before the rig arrives, not a finding for any particular block. Two sites a street apart can classify differently, which is why every report starts with boreholes on your site, not the neighbour's.
We cover the whole area, not just the suburbs listed. This area has its own fixed site-classification fee; check it with your postcode above.
How it works
Send the site address and what you are building. Standard sites get the fixed fee straight away; anything else gets a scoped quote before we book.
We come out with a rig or hand equipment, drill the boreholes, log the soil as it comes out of the ground and take samples for the laboratory where the report needs them.
An engineer at Australian Ground Sciences checks and signs the report. It goes to you as a PDF, ready for your builder, slab designer or certifier.
