Concrete scanning enables you to visualise major structural components within concrete. Markings allow you to avoid these areas when performing invasive work, preventing damage to the concrete structure. Damage to rebar and post-tension cables can be extremely dangerous, potentially causing immediate structural failure and injuring or killing those on site. Damage to electrical services within the concrete can cause electrocution or death.

Concrete is scanned with the use of ground penetrating radar. A device is passed over the concrete’s exposed surface, sending a high frequency electro-magnetic pulse into the concrete. The signal is deflected back to the device at different time intervals depending on what type of material is found in the concrete and how deep the material is. An experienced technician will be able to determine the type and location of the material based off of this reading.
