Parramatta, Penrith, Blacktown, Fairfield and Cumberland councils
From Parramatta out to the Nepean, western Sydney sits mostly on the Wianamatta shales and, further out, the Londonderry Clay and the river terraces. Reactive clay is the rule, which is why the classification matters, and the volume of new housing means we are out here most weeks.
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. Standard sites here are the Zone 1 fee.
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.
