Our professional core drilling service provides precise, clean penetrations through concrete for plumbing, electrical, HVAC, and structural purposes. Every core drill location is pre-scanned with GPR technology to ensure safe drilling zones, protecting post-tension cables, rebar, and embedded services. We also extract concrete core samples for laboratory testing and quality verification.
Delco Industries operates across Gold Coast, Brisbane, and all of South East Queensland, providing core drilling services to structural engineers, principal contractors, builders, body corporates, and government agencies. Our reports are engineer-certified and accepted by all Queensland councils, certifying authorities, and structural engineering firms.
Every engagement is led by qualified structural and civil engineering professionals — not just field technicians. This means every data set is interpreted with an engineering lens, and every report you receive is ready to be used directly in structural decision-making. We comply with all relevant Australian Standards including AS 3600, AS 2159, AS 1012, and AS/NZS 1170.1 where applicable.
