NON-DESTRUCTIVE TEST
Non-Destructive Testing (NDT) is the examination of an object or material with technology that does not affect its future usefulness. NDT can be used without destroying or damaging a product or material. As it allows inspection without interfering with a product’s final use, NDT provides an excellent balance of quality control and cost-effectiveness.
Today modern Non-Destructive tests are also used in manufacturing, fabrication and in-service inspections to ensure product integrity and reliability, to control manufacturing processes, lower production costs and to maintain a uniform quality level. During construction, NDT is used to ensure the quality of materials and joining processes during the fabrication and erection phases, and in-service NDT inspections are used to ensure that the products in use continue to have the integrity necessary to ensure their usefulness and the safety of the public.
Cover-Meter & Scanning Rebar Test
This test is conducted by passing a pulse of ultrasonic through concrete it used to measure the thickness of concrete cover over steel reinforcement bars and metal pipes, furthermore it is also used to identify the location, orientation and diameter of reinforcement bars (rebar).
Rebound Hammer Test
Is a Non-destructive testing method of concrete which provide a convenient and rapid indication of the compressive strength of the concrete. Rebound hammer is also known as Schmidt’s Hammer or Swiss Hammer as it is invented by Ernst Schmidt, a Swiss engineer.
Hardness Test
Is a method employed to measure the hardness of a material. Hardness refers to a material’s resistance to permanent indentation. There are numerous techniques to measure hardness and each of these tests can identify varying hardness values for a single material under testing and also to determine the quality of steel structures installed and used to evaluate the capacity and strength of steel structures.
Half-Cell Potential Test
This test is used to determine the probability of corrosion within the rebar in reinforced concrete structures. This technique dives into the specifics of concrete corrosion, the half-cell potential technique for testing concrete corrosion, and the ways in which the data from the half-cell potential test can be interpreted.
Ultrasonic Thickness Test (UTT)
This testing is a method of performing non-destructive measurement of the local thickness of a solid element basing on the time taken by the ultrasound wave to return to the surface. The purpose of this testing is to determine material thickness and to measure the thickness of concrete, steel, pipe, glass, coatings and/or linings. Our technicians have been trained to calibrate the UTT gauges based on materials.
Ultrasonic Pulse Velocity Test (UPV-Test)
This test is conducted by passing a pulse of ultrasonic through concrete to be tested and measuring the time taken by pulse to get through the structure. Higher velocities indicate good quality and continuity of the material, while slower velocities may indicate concrete with many cracks or voids.
