Common questions

How deep can your drilling rigs go?

Depth depends on ground conditions and rig access, but our track- and vehicle-mounted rigs routinely reach the depths required for standard residential, commercial and infrastructure foundation investigations. We confirm expected depth against your project brief before mobilising.

Can you drill on a tight residential block?

Yes — we run smaller, manoeuvrable rigs for restricted-access residential sites in addition to our standard truck-mounted equipment for larger commercial and infrastructure jobs.

What do I get at the end of a drilling program?

Sealed soil and rock samples for lab testing, drilling parameter logs, and lithology/strata logs — everything your design engineer needs, delivered per our standard turnaround.
