CWHR has recently established facilities for Non-Destructive Testing of concrete with a range of sophisticated equipment and existing manpower trained to conduct such testing services.

The importance of Non-Destructive Testing Methods and procedures have gained importance manifold after the October 8 earthquake. Structures that failed or collapsed during the earthquake will have to be reconstructed, but there are still a large number of structures that may not have failed but require inspection to ascertain their structural adequacy through NDT methods.

S. No.
Schmidt Hammer Test:
For determination of surface hardness of concrete and estimation of concrete strength. Test performed in accordance to ASTM C-805.
5,000/- per point (one point equivalent to area of 6'-inch diameter)
Micro Core Extractor:
Extraction of Concrete Micro Cores (1” dia). Test performed in accordance to ASTM C-42.
15,000/- per point (including extraction & testing of Micro Core)
Detection and measurement of reinforcement in Concrete by using Re-Bar Locator
2,000/- per point (one point equivalent to one square meter or one running meter)
Determination of quality of existing concrete by using ultrasonic pulse velocity.
2,000/- per point (one point equivalent to one square meter or one running meter)
Moisture Meter used for measuring the moisture level of non-conductive and porous construction materials.
50/- per test
