Concrete Structure Investigations Ltd

Concrete Structure Investigations Ltd Concrete Structure Investigations Ltd (CSI) carry out reinforcing verification in concrete structures.

CSI technicians have full training in the use of the most advanced Hilti scanners and software. Concrete Structure Investigations access, evaluate and report (directly or indirectly) to professional Consulting Engineers, Building Owners, Councils and Government Institutions on areas of existing reinforcement. The engineers require data and images demonstrating the bar size, cover and location of t

he steel within the concrete structures. Consulting Engineers use CSI reports to evaluate the overall integrity of the building. Concrete Structure Investigations locates the position of existing reinforcing bars in slabs, walls, beams and columns. The information collected enables both reinforcing hit prevention during seismic upgrading of existing buildings and installation of general structural steel connections into concrete components.

The industry is moving in the right direction 📐

CSI pioneered ultrasonic testing for Drossbachs and contributed to the SESOC Guidance Papers that set the standard. A year on? We're seeing real results: better grouting quality, more QA at the construction phase, and greater confidence across the board.

It's what happens when consultants, contractors, researchers, and industry bodies collaborate with intent.

This is how New Zealand's built environment gets better.

Great NDT starts before the scanner switches on.

Understanding the structure, its materials, geometry, load paths, and likely defect zones, is what makes the difference between accurate results and false readings.

It's how we choose the right method, target the right areas, and deliver findings you can actually act on.

How strong is your slab, really? 🏗️

Non-destructive testing (NDT) lets engineers figure out exactly what a concrete slab can handle - without drilling, coring, or damaging the structure.

Our latest blog walks through the full workflow: baseline surveys, material characterisation, strain + deflection monitoring, and what changes when you can only access the slab from above.
