Non-Intrusive Objective Investigation Methods: Advantages over Traditional Tap Testing

When it comes to assessing the condition of concrete structures, tap testing has long been a popular choice. However, this method can be highly subjective, and the results may not always be repeatable or accurate. That's where objective non-intrusive investigation methods come in - they offer a more scientific approach that can deliver more, better, and repeatable information than tap testing.

At TRACE-SI, we have developed specific workflows that allow us to obtain objective and accurate data from non-intrusive methods such as ground penetrating radar (#GPR) and #ultrasonictesting (#UT). By using these methods, we can map areas of delamination and other defects within concrete structures, providing a detailed picture of their condition.

One of the main advantages of using GPR and UT is that they are objective methods, eliminating the subjectivity associated with tap testing. The results can be quantified and analysed in a more controlled and repeatable manner, providing greater confidence in the data. This makes them an ideal alternative or follow-up to tap testing, particularly when accurate and reliable data is required.

Another advantage of using GPR and UT is that they can detect subsurface defects such as corrosion. GPR uses high-frequency electromagnetic waves to penetrate materials and create images of their internal structure, while UT uses high-frequency sound waves to detect flaws or measure material thickness. By using these methods together, we can cross-analyse the data and increase the accuracy and reliability of the results.

By repeating these investigations over time, we can provide assessments of changes in defects, allowing us to track the condition of a structure over time. This can help identify any potential issues early on before they become more serious and costly to repair.

In conclusion, objective #nondestructivetesting and investigation methods such as GPR and UT offer significant advantages over traditional tap testing. They provide more accurate, repeatable, and reliable data, allowing us to make informed decisions about the condition of concrete structures. At TRACE-SI, we have developed workflows that allow us to obtain the most comprehensive and accurate data possible, ensuring that our clients have the information they need to make informed decisions about their assets.
