Non destructive testing of concrete structures (NDT)
Background
For as long as concrete structures have been made, there has been a need to look inside them. After a structure has been completed, questions often arise, such as:
- Have sufficient amounts of the correct reinforcement been used?
- Is the concrete quality satisfactory, and is the concrete thick enough?
In most cases, random destructive tests are carried out in order to obtain the answer to these questions.
NON DESTRUCTIVE TESTING
Increasingly, SGS INTRON makes use of non destructive testing (NDT) to obtain answers to these questions. In this way, SGS INTRON can inspect a structure without damaging it. The main advantage of these techniques is that the total structure can be examined and the measurements can often be carried out more rapidly. This results in a faster and more reliable test result.
SGS INTRON can use NDT techniques to examine structures in order to determine:
- Floor thickness
- Concrete cover
- Quantity and location of reinforcement
- 3D radar measurement of reinforcement in floor
- Localisation of prestress
- Corrosion of reinforcement
- Concentrations of moisture
- Lines/underfloor heating
- Infrared image of underfloor heating
The techniques used by SGS INTRON for non-destructive testing include
radar, electromagnetic scanning
(Ferroscan), ultrasonic scanning, resistance measurements, and infrared thermography.
