WALL
RAIN
:explode: Absobtion
-
-
-
:check: Painting > Hinder damp, not vapour
:check: Cavity wall
-
:explode: Mortar squeeze
- Wall tie -->
- Horizontal cracks
- Rust -> Expansion
-
-
-
-
:check: JOINT
Solutions
Polymeric seal:
- double curves --> best adhesion
Open drained:
- outer groove vs rain
- inner air/weather-tight sealant
Backing rod (elastic thickness)
Double right angle ->
INFILTRATION
-
-
Voids like in
- Spray foam
- Dislodged boards
-
Insulation
-
None: drying wall, evaporation inside
-
:pen:
Where:
- connection with basement
- around windows
- eaves
GENERAL
- Draught
- Cold areas
- Damage of moisture
- Water flowing
-
-
PLASTER
- Falling
- Differences in colour

SCREEN DRAINED
Water may pass, but drained
WINDOWS
:fountain_pen: Casement
- Sealing
- Moisture on the frame
:explode: Condense
--> dampness inside, casement damaged
:explode: Moistrure in the glass
--> opaque areas, damaged frame
--> insulation
Problems
Bulging/Leaning walls
:explode: Vibration by machinery
- Increased load
- Wrong thickness design
- No wall-floor restrain !! --> lateral movement
-
Cracks
- fine < 1.5 mm
- medium
- large > 10 mm
-
Open horizontal --> Vertical settlements
- Open vertical --> Horizontal movements
- Horizontal + Vertical --> Transverse failure
:check: EIFS/ETICS
- Plaster
- Insulation (carrying)
- Gympsum/metal board
- Studs & Batts
- Damp proof membrane
- Inner lining
