This PDF About Historic Masonry deterioration and preventative maintenance, is decidedly not "gamish" though I found it pretty interesting to read.
Using that PDF as a source when a Dwarf player is traipsing around a dungeon and asks, "do I notice anything about the condition of my surroundings?" If the GM determines there should be something Roll on the chart below.
(Roll 1d12 for feature, 1d10 for severity)
Severity 1-4. minor 5-7.moderate 8-9.pronounced 10.concerning*
- Blistering: Swelling and rupturing of a thin uniform skin acrossed the masonarys bedding plane. A the concerning level could represent something being hidden behind a masonry false front, or a hollow area behind a wall.
- Chipping: Large pieces are missing , usually on corners, At the concerning level , this could show signs of alterations done to the masonry, or direct attempts to damage the masonry in the past.
- Coving: Erosion undercutting the base of the masonry. At the concerning level, could affect the stability of walls.
- Cracks: Are cracks in the masonry. at the concerning level they could represent an unstable are of construction , or an area that has shifted in elevation / grade.
- Crazing: A small spider web of cracks usually in glaze or in concrete. an the concerning level this could show an area that has flooded in the past.
- Crumbling: Brittle masonry that falls away. This shows that a masonry might be quite old. At the concerning level, could affect the stability of walls.
- Delamination: Large laminate sheets fall away from the surface of the masonry. At the concerning level these sheets could be an environmental to those passing by, depending on size and weight.
- Erosion / Weathering: Wearing away for corners and edges by natural forces. A clever dwarven mason could use this sign to guess at the age of a structure. At the concerning level it could show an area that experiences seasonal floods, or that the masonry is unstable.
- Pitting: Small pock marked areas due to the removal of individual components of the masonry. At the concerning level this could point to the presence of chlorine gas or acids.
- Subflorescence: Build up of salts within the masonry. Hard to detect directly some white powdery buildup on the outside of the masonry could be taken as a sign. At the concerning level this could point to old unstable masonry, a void behind a wall, or an area that experiences dramatic temperature extremes.
- Surface crust: The movement of moisture out of masonary caries minerals which form a crust. At the concerning level this rust may hide, or impede the functioning of ancient stone doors. A concerning crust might also warn a dwarf of weak stones or stones which have effectively disintegrated leaving only the crust behind. (Don't walk on those!)
- Rising Damp: The suction of moisture into masonry from the ground via capillary action is called rising damp. At the concerning level this could show a dwarf that a building is badly drained, and in older structures may not be completely stable. It could also be a clue that there is water below a structure.
