Rock Auger Drilling Geelong
Much of the ground around Geelong, the Golden Plains and out towards Colac sits on basalt — and a standard auger simply spins on top of it. Just Walls runs dedicated rock augers with hardened teeth that cut through rock and compacted material, so your footings, piers and post holes go to their designed depth instead of stopping where the ground gets hard.
When You Need a Rock Auger
- Bored piers and footings on rocky building sites
- Retaining wall post holes in hard or shaley ground
- Fence and structural post holes through surface rock
- Foundation holes where a site investigation shows rock
Drill to Depth, First Visit
There is nothing more frustrating on a build than an auger contractor who arrives, hits rock and leaves. We carry both standard and rock augers on the truck, matched to excavators from 2 to 14 tonne, so we can step up through attachments on the spot. If the ground needs more than an auger, we can also bring rock breaking equipment to the job.
Working With Your Engineer
Bored piers in rock are usually specified by an engineer — diameter, depth and founding material. We drill to those specs and keep the holes clean and ready for inspection, steel and pour, coordinating with your builder or concreter so nothing sits open longer than it needs to.
Rock Auger FAQs
What is the difference between a rock auger and a normal auger? +
A rock auger has heavy-duty flighting and hardened picks designed to grind through rock, where a standard soil auger has wider flighting for loose material. We carry both and swap based on the ground.
Can you really drill through basalt? +
Yes — basalt floaters and caps are common around Geelong and our rock augers handle them. For very large or solid rock we combine drilling with rock breaking equipment.
How do I know if my site has rock? +
A soil report will usually show it, and local knowledge fills the gaps — after two decades working this region we know which areas hide rock. If we suspect it, we bring the right attachments from the start.
