NDT, Structural & Building Inspection

Non-destructive testing (NDT) refers to the testing/verification of materials, in order to check, inspect or evaluate the surface for the presence of any internal flaws, defects, and discontinuities, without damaging it or impairing its future usability. Basically, NDT testing is used to investigate the material integrity of the test item.

Importance of Non-destructive testing:


There are certain structures like huge machines (used in industries), massive pipelines, concrete structures, bridges and flyovers, pressure vessels, and many sophisticated machineries and structures, which because of their enormous size and complexity have a certain natural risk factor associated with their current and future performance. The applications of this type of testing mainly apply to expensive items and structures.

Classification: NDT techniques can be categorized or classified into a number of types depending on the physical or chemical property utilized for the particular method. Some of the basic types are Visual, Liquid Penetrant, Magnetic-particle, Radiography, Eddy Current testing, and Ultrasonic.

Advantages or Uses of Non-destructive tests are:


•    Ensuring product integrity, and hence its reliability.
•    Form part of Preventive Maintenance technique.
•    Controlling manufacturing processes, and lowering manufacturing costs.
•    Maintaining top-class Quality control, and aiding in better product design.
•    Keeping intact manufacturer’s reputation, and hence building trust among its customers.
•    Preventing accidents, and hence safeguarding human lives.


Conducting NDT tests require an enhanced level of skill, experience and knowledge on the part of the operator, since the test results vary significantly with the expertise of the operator. Modi Laboratary   has a team of extremely talented and diligent NDT inspectors, who are adequately trained and experienced in NDT testing/inspection of Structural and Building materials, both laboratory and on-site testing. We regularly provide NDT testing services to various industries like hydro-power, thermal power, fertilizers, petroleum refineries etc. We can also provide Residual Life Assessment and Structural safety tests for concrete bridges, water tanks and old buildings including those damaged by fire, as well as load test on bridge structures.
