The Basilika of the Mother of Sorrows in Limanova, Poland, is a sandstone building, erected between 1911 and 1918. The building material originates in the Carpathians and was taken from the Maegura-Formation.
The massive damage to the 100-year-old church, which showed itself in the pre-state, can be explained by the special characteristics of the Carpathian Sandstone. It is a type of rock that consists of lime, clay and added mica. It decomposed with time into individual layers. The uppermost layers had partially detached from the facade. Due to weathering processes, the outer shell had taken profound damage. In the past there had been attempts to fill in the gaps with the help of mortar and to glue the damaged areas. This caused further damage.
In shady areas lichens and mosses proliferated and kept the facade in a permanently wet condition. The lower sections showed strong saline blooms, as the porous stone sucked up salty moisture from the ground like a sponge. The wooden construction elements of the tower were cracked and partially infested with mold, the load-bearing capacity had suffered. The roofing consisted of mostly damaged bricks and tiles.
