Rock and Minaeral Consulting - International Services

Investigation and evaluation of natural stones/dimension stones - quality assurance

During the last decades the use of dimension stone for structural or technical puposes has considerably increased. This requires increasingly sophisticated investigations concerning its properties, weathering behavior and resistence against chemicals. In earlier times only local dimension stones had been used due to transport problems. For this reason the number of different varieties was limited. Todays market is dominated by a vast number of different rocks from all over the world whose technical properties are poorly known.

We offer an all round service including quality monitoring and assurance of rough and dressed stones. Further we investigate stone damages and determine their causes. All analyses and standard tests are carried out in cooperation with research institutions and testing laboratories of international reputation.
