FAMILY OWNED • INDEPENDENT • SYDNEY BASED
Sydney, Australia
Solid Foundation.Build With Confidence.
Whether you are extending a tight Surry Hills terrace, building a new home in Dural, or planning a duplex in Kellyville, an accurate geotechnical report is the foundation for every decision that follows. We don't just drill holes; we deliver the site data and plain-English advice needed to reduce costly guesswork, keep your project moving, and give your structural engineer the reliable parameters required for design.
Our Foundation & Mission
SFGEO is a locally-owned, independent geotechnical consultancy based in Marrickville, built on 15 years of hands-on Sydney experience across residential site classifications, bespoke architectural homes, and landmark infrastructure.
We were founded on a straightforward belief: that clients deserve direct access to a professional that cares about their project, not a corporate firm that passes your project down the chain. When you work with SFGEO, you work with our consultants, start to finish.
Our Principal Engineer has contributed to Sydney Gateway, the M12 Motorway, Western Sydney Airport, and the Canterbury Aquatic Centre. That depth of experience now serves your project with the responsiveness, transparency, and personal care that only an independent practice can offer.
Direct Access. Always.
Call us, email us, turn up. You reach your consultant directly — no admin queues, no message chains.
Sydney Is Our Backyard.
Locally owned, locally based. We know Sydney's ground conditions, its councils, and its sites — because we've worked them for 15 years.
On Site. On Time. On Call.
We mobilise fast, deliver reports quickly, and pick up the phone when you need an answer. Quality work, without the wait.
