Salt mist test can be used to evaluate the durability of porous materials. Besides mass loss, the paper discusses the use of DRMS (drilling resistance measurement system) to monitor changes in strength due to salt crystallisation. Drilling resistance was used to characterize changes promoted in very different lithotypes, namely carbonate rocks and one variety of sandstone. The results show that this technique is able to identify fingerprints of the presence of salts on the profiles seen as increments in resistance. Damage zones can also be detected on the profiles of the aged samples, after desalination. The results clearly indicate the influence of moisture content on the drilling data. Although considered as a minimally invasive action, the method produces a small hole that has some influence on the ongoing decay process. In this paper illustrative examples are presented, some advantages and drawbacks are indicated in order to correctly evaluate the results when it is possible to use it to evaluate the action of salts.
