What’s in your walls? Is it safe to drill? Before you start cutting into that concrete wall, slab, beam or column, contact Safety First Locators for a comprehensive concrete scan.
Why do I need a concrete scan?
Concrete structures can conceal cables, pipes, ducts and reinforcement structures. Drilling or cutting into any of these can damage tools, infrastructure, and most importantly, people.
Before any core drilling, dyna drilling, wall cutting or removing concrete slabs or walls, always ask for a concrete scan.
What can concrete scanning identify?
Is there a gap beneath a concrete slab? Christchurch has had plenty of seismic shifts, so scanning your concrete slab can make sure your structure is still safe and sound. Particularly an issue in post-quake Christchurch, before you lay foundations you need to know if the ground is safe to build on. Our GPR surveys can detect underground cracks and voids beneath the surface that could pose major risks in the event of another earthquake.
Slab thickness assessment
As well as identifying any gaps or voids under the concrete, we can investigate the thickness of the concrete wall or slab to see if it needs reinforcing and is still up to standard.
Reinforcement posts and tension cables
Are there any steel mesh or rebar reinforcement within the concrete structure? Locating and identifying any steel structures or post-tension cables within the concrete will give you a better idea where to drill.
Cables, ducts and live electrical
With many structures encasing live wires, underfloor heating and ducts within concrete slabs and walls, cutting or drilling without knowing where the utilities are located can cause serious damage and harm.
Changes to New Zealand's building code and damage caused by recent Canterbury earthquakes means many buildings in Christchurch and across the country need earthquake strengthening repairs.
Unfortunately, understanding the extent of the damage is not always visible to the naked eye. To get a more accurate picture of the damage and extent of the strengthening work required, you need a comprehensive concrete scan.
Sadly, many concrete GPR scans are showing that buildings in New Zealand have not been constructed according to their plans, and have either defective or are missing critical structural components.

Accurate concrete scanning
All we need is a site plan and a clearly defined area to scan. Just leave the rest to us. All our findings from concrete scanning your site will be clearly marked on the concrete structure.
In addition to our report, we will walk through the site with the project manager, and those responsible for drilling or cutting into the concrete. Our comprehensive handover process and dedication to safety means we want everyone directly involved with this project to understand the risks involved, as well as the limitations of the scan.
South Island concrete scanning
Based in Christchurch, the Safety First Locators team can respond across the South Island for concrete scanning slabs, sites and structures.
As a beforeUdig Certified Locator in the South Island, before you start work on any concrete structure, contact the experienced, accredited team for a concrete scan on 03 366 3242.
