Accurate, Non-Destructive Imaging for Coastal Construction
At Dowd’s Pipe and Cable Locating, we’ve spent years helping Wollongong builders, renovators and engineers uncover what’s hidden inside their concrete. Our Concrete Scanning Wollongong service uses Ground Penetrating Radar (GPR) to precisely detect rebar, conduits, voids, and post-tension cables—ensuring every project is safe, compliant and efficient.
From Thirroul to Dapto, Port Kembla’s industrial sites to Shellharbour’s new developments, our scanning technology reveals exactly what’s inside slabs and walls before you cut or core. It’s a smart, non-invasive way to avoid damage, delays and unnecessary repair costs.
Why It Matters in Wollongong
The Illawarra’s coastal conditions create unique challenges for concrete structures — salt air, humidity, and corrosion can change material density and conceal embedded hazards. Whether you’re working on a beachfront renovation in Woonona or a multi-storey development near Crown Street, having accurate subsurface data means you can plan confidently and meet Australian WHS standards.
Our technicians are locals who understand the coastal geology and construction history of the region. This insight helps us interpret GPR data accurately and adapt scanning frequencies for the best results on different concrete compositions and thicknesses.
