Non-destructive tools capable of measuring the condition and geomechanical properties of construction materials through time are of considerable value in engineering. Here, the ability of the Equotip durometer (Proceq, type D) to detect changes in the hardness of concrete and rock exposed to marine conditions was tested. Results indicated a progressive loss of hardness for limestone, while concrete hardness increased. Granite showed no significant change. Our results relate to alteration of the materials primarily via chemical and biological weathering. The Equotip is sensitive enough to detect subtle changes in the condition of construction materials over relatively short periods of time.
