    The aim of this study was to investigate the causes and symptoms of destruction of stone ventilated facades. 13 buildings in Krakow have been selected to determine to what extent this destruction can be prevented. Sandstones from 5 Polish deposits have been used to cover these 13 buildings. Certain factors and evidence of damage have been identified. The following tests have been performed: petrographic characteristics, water absorption, resistance to forces pulling out construction dowels and fracture toughness. Then, after application of hydrofobization, water absorption was checked once more. Later, the impregnate was used and the resistance to forces pulling out construction dowels and fracture toughness were evaluated. The final conclusion is as follows – the types of damages are correlated with the properties of stone, and that the hydrofobization and impregnation can reduce the rate of the façade destruction.
