Durability, strength, and viability of any structure are crucial before occupying it for any use. Any structure, be it new or an old one (which is open for re-occupancy) can be assessed if required. Though it is not a prerequisite to have it done for the existing owner or a prospective owner. However, it is always advisable to have it done in order to learn and evaluate longevity, resistance, and stability. Though the common method, which is used, is to assess the quality by collecting a specimen of the structure while it is under construction, the result of the specimen can differ from an erected structure. For that, Non-Destructive Testing methods are the most reliable. They not only give the true picture of the tenability of the concrete structure but also elaborate on factors like hardness of the concrete, resistance, rebound capacity, and a structure’s suitability for any intended use.
Non-Destructive Testing does not add or lessen the weightage of any structure. However, it does help in learning about a structure’s strengths and weaknesses before it is used. Of course, weaknesses, here refer to the areas which can be overhauled to reinstate the strength of a structure. The cost that the rework would incur, is of course upon the occupant to decide, whether he/she wants to bear. For instance, if an already erected structure is being used for storing heavy-load machines/equipment then it is imperative to have a strength measurement in your hand.
The Non-Destructive Testing helps in determining the elements of a structure like;
The non-destructive testing method is beneficial as it does not impose any harm on the structure as is done during coring or testing through other destructive methods. There are many methods to ascertain different factors of a structure like moisture content, humidity level of a structure, cracks, or position of steel bars. Any discrepancy can adversely affect the endurance of the structure. The different testing methods are;
