What is the purpose of using a moisture meter in bridge inspections?

The purpose of using a moisture meter in bridge inspections, particularly in the context of assessing timber members, revolves around evaluating the moisture content to ensure structural integrity and longevity. Timber is susceptible to decay and deterioration when it retains excessive moisture, which can lead to significant structural issues. By measuring the moisture content, inspectors can determine if the timber components are within acceptable limits, identify areas at risk for decay, and make informed decisions about maintenance, repairs, or replacements.

While other materials in bridge construction may have their own specific testing methods, the moisture meter is particularly tailored for wood. This makes it an essential tool in safeguarding structures that utilize timber, ensuring that inspections are thorough and that necessary actions are taken to maintain safety standards.
