Concrete Worm utilises the latest technology for non-destructive inspection and evaluation of concrete structures. Our Hilti Ferroscan is used to quickly, easily and safely locate embedded steel reinforcing and cabling within concrete structures prior to cutting, coring or drilling.  Scanning is also used to quantify the amount of reinforcing within a beam or column, without the need for breaking the structure.  We also offer a core crushing service for the compressive testing of concrete. In this process core samples are taken from a structure and sent to a laboratory where they are crushed under pressure to measure their compressive strength.
