SFGEO is a Sydney-based geotechnical consultancy and drilling contractor built for professionals who need fast, reliable ground data and a team they can actually talk to.

We work with residential developers, civil and infrastructure contractors, commercial developers, architects, and environmental consultants across Greater Sydney. Whether you need a rapid site classification, construction-phase sign-offs, or a specialist drilling crew for your next environmental or geotechnical investigation, we have the people and the equipment to deliver.

Our Services:

🔍 Site Classifications (AS2870) & Geotechnical Investigations (AS1726)
🏗️ Construction Phase Support — footing inspections, pier assessments, proof rolls, engineered fill compliance (AS3798)
📐 Geotechnical Design — pile design inputs, retaining wall parameters, bearing capacity, working platform assessments
🚜 Drilling & Sampling — we operate our own 4WD-mounted drill rig for auger drilling, DCP testing, tight-access drilling, and environmental soil/groundwater sampling (PSI/DSI Stage 1 & 2)

Looking for additional drilling capacity? We regularly subcontract to other geotechnical consultancies and environmental engineers who need dependable field support without the overhead of maintaining their own equipment.

Independent, insured, and professionally affiliated. We're the kind of firm that gives you a straight answer and gets the work done.
