Destructive and non-destructive testing?
There are many variations of destructive and non-destructive testing. Destructive means the test sample or area will be irreversibly damaged or destroyed during sampling and laboratory testing. An example of destructive testing we offer is diamond drilling which is also known as concrete coring in the construction industry.
This method of testing usually requires 70 mm / 100 mm / 150 mm cylinders to be cut or drilled from the floor with diamond-tipped barrels, thus the name diamond drilling. The test sample removed is usually compression tested or a chemical analysis performed to ascertain the material properties, cement content and much more. The minimum sample length for this test is 110 mm.
As with destructive testing, there are many variations of non-destructive testing and these do not generally destroy or damage the area of the test. Pundit ultrasonic meter and Schmidt rebound hammer are commonly used and can give an indication of problems or strength straight away.
All methods discussed above are performed on hardened concrete and usually sampled in-situ on site.
