| Caption: | Detail of building in Chester Street, Edinburgh, Lothian Region |
| Description: | The image shows severe decay of sandstone masonry immediately below a window sill. This decay has been caused by the penetration of excess water into the stonework as a result of a defective gutter and down pipe higher up the building. Water is transported through the porous structure of the sandstone, causing damage by dissolving out soluble mineral constituents and reacting with other minerals such as clays and iron oxides. Some of the secondary products formed from these reactions can expand to many times their original volume and exert great physical pressure causing the sandstone to disaggregate. |
