Investigation of causes of damage to natural stones

Petrographic expertise regarding defective natural construction stones, scientific identification of the cause

Defects in natural stones may have different causes which can only be clarified by an expert. Most common are undesirable discolorations, but also flaking and fracturing may occur. In most cases it is caused by interactions of the natural stones with external fluids resulting in complex mass transport and mineral transformations.

In the case of damage we assist you with competent expertises.
