NDT Laboratory

Service offered:

For health and condition assessment of concrete structures, Non-destructive evaluation techniques play an important role. Non-Destructive Testing Lab of NCCBM has a range of equipments to carry out Non-Destructive Testing and evaluation through techniques like Rebound Hammer Test, Ultrasonic Pulse Velocity test, Half-cell potential measurement, Rebar detection & concrete cover depth measurement, Concrete Core extraction, In-situ Carbonation depth measurement, Electrical Resistivity Test, Air permeability test, Crack width and crack depth measurement, Pull off Test on repair overlays, Measurement of Dry Film Thickness of coating using DFT meter, etc. These evaluation techniques are frequently made use of in quality and durability assessment as well as condition assessment of existing concrete structures. The laboratory has NABL accreditation as per ISO 17025-2017 for UPV Testing and Rebound Hammer testing
