Abstract: Stone facade blocks and panels have been used for the construction of buildings and other structures for hundreds of years. Based on the investigation of over fifty buildings of various ages and distress, observed defects could be classified into several categories. They include material flaws and durability, lack of proper details to prevent water infiltration into the interior of the building, deterioration of anchors between stone pieces and between stones and a buildings structural systems, improper construction methods, and inadequate design to accommodate movement of the overall structure and/or movement between the stone cladding and connections to the backup walls.
Over the years thicknesses of the stone panels or blocks used for the exterior facades of the buildings have been reduced. In earlier times, the stone blocks had been used as a load-bearing elements for exterior walls. As the building heights have increased over the years, stone blocks have been used mainly as a veneer with thicknesses of 10 cm. In the last fifty years, thicknesses of the stone panels has been reduced to 2.5 cm to 3 cm. Due to a reduction of thicknesses, mechanical properties and durability of these panels became important. Durability and structural stability of thin stone panels has become a major factor in design
