Core sampling is the gold standard for concrete inspections – AITHON makes this possible without asset downtime, without endangering workers, and without compromising on results.
Our technology allows for the safe and precise extraction of concrete core samples at hard-to-reach locations — no scaffolding, no rope access.
The mission in short
At a highway bridge in the mountains, critical locations for corrosion were identified. To continue safe operation, ground-truth samples from the asset were required. With AITHON, these samples were extracted without closing the road and in the same time as it would have taken human workers. The resulting cores were sent to lab testing for chlorides and carbonation.

Frequently asked questions for drone-based core sampling
How does core sampling with a drone work?
Core sampling is a multi-step process, with three phases: preparation, extraction, reinstatment. In preparation, a scan of the worksite can be performed to prevent damaging rebars, or to gain more information on the site. Extraction involves drilling the core and removing it from the asset. Reinstatement is the cleanup of the hole and refilling it such that water ingress is prevented.
AITHON can perform all of these steps, but not all are necessary always. Get in touch to see how drone-based core sampling is best used for your situation!
What is done to prevent damaging the asset?
Core sampling can damage structures, if not done carefully, by damaging rebars or providing a location for water and contaminants to enter the material.
By scanning for rebar and other structures prior to drilling, as well as grouting the hole after core extraction, the asset stays in good condition.
What types of samples can you extract?
AITHON can extract concrete cores up to 80mm in diameter and 200mm in length. Depending on your specific application, this can be modified.
How does drone-based core sampling help in inspecting assets?
While many other methods exist to assess infrastructure assets, core sampling provides a unique perspective, by giving an in-depth insight into the material from the asset and location of interest. In many cases however, limited access leads to guesswork and ineffective measures being decided upon. With AITHON, you can get the full picture at critical locations on assets, greatly improving the quality of your work without costing more or endangering workers.
