In the week before last, we looked at a stoop that was clad with a relatively thin stone. This stone is installed a bit less like typical masonry in a bit more like tile. The stone is essentially cut relatively thin and then mortared against a more substantial masonry substrate. You can see several pictures below where there are signs of significant deterioration. Some of the main causes of that deterioration follow in the list below.
- Water
- Infiltration
- Freeze-Thaw Cycles
- Subflorescence
- Dissolution
- Crystal Formation
- Decay
- Acid Induced
- Chemical Weathering
- Human Defects
- Poor Installation
- Mortar Incompatibilities
