Safe, Precise and Non-Destructive Subsurface Imaging for Sydney Projects
At Dowd’s Pipe and Cable Locating, we understand the pace and pressure of Sydney construction. From city towers in Parramatta to retail redevelopments in Alexandria and high-rise fit-outs in the CBD, every drill or core hole must be executed with absolute confidence. Our Concrete Scanning Services Sydney use advanced Ground Penetrating Radar (GPR) to detect rebar, conduits, post-tension cables, voids and structural elements before any penetration begins.
Concrete scanning is now a vital part of safe, compliant building and renovation in Sydney’s dense built environment. Striking a hidden cable or post-tension tendon can halt a project, compromise structural integrity, and lead to serious safety and financial consequences. That’s why builders, engineers and electricians across Sydney rely on our experienced technicians for precise, real-time imaging that helps them proceed with confidence.
Why Concrete Scanning Matters in Sydney
Sydney’s construction landscape is uniquely challenging — complex multi-storey structures, layered utilities and limited access points mean guesswork isn’t an option. Our non-destructive GPR technology allows you to see inside slabs and walls without breaking the surface, identifying potential hazards that could cause costly delays or damage.
We help ensure compliance with Australian Standard AS 5488, WHS regulations and local council safety requirements, giving contractors peace of mind. Whether you’re cutting cores on a Barangaroo development, drilling anchors in Chatswood, or conducting refurbishment works in Surry Hills, our scanning process provides the clarity needed to plan safely and efficiently.
Key Applications of Concrete Scanning Sydney
Our technicians perform hundreds of GPR scans across Sydney each year, supporting construction, electrical, plumbing, and fit-out teams. Typical applications include:
- Suspended slabs and carpark structures: Detect reinforcement, post-tension cables and conduits before coring or anchor drilling.
- Concrete walls and columns: Identify embedded rebar, pipes or voids before cutting openings or installing services.
- Bridge decks and infrastructure: Assess reinforcement layout, corrosion, and voids for maintenance and rehabilitation.
- Footings and foundations: Verify as-built conditions or confirm clear zones prior to structural modifications.
- Concrete-encased services: Map conduits and utilities before excavation or trenching.
Our approach is non-invasive, fast, and accurate, producing detailed cross-sectional images and data maps on-site. Every scan is tailored to site conditions, concrete density and project requirements — ensuring that results are practical and actionable.
