FOUNDATIONS
and FLOOR
-
Sags
-
-
-
:explode: Water level change/slopping
- Flowing water -> Soil erosion
- Mining activities
- Clay shrinkage !!
-
Damp
-
-
-
- Discoloration
- Peeling decoration
:explode: Salt in groundwater ->Evaporation on surface --> Absorption
- Floor under sidewalk --> Penetration of water
- High water table -> Pressure on wall/basement
-
STONEWORK
:explode: Original orientation
- Driving rain
- Pollution / Salt-sea
- Water absorption / Frost
Crystallisation of salt
--> Discoloration
-
-
TIMBER STAIRCASES
-
-
:pencil2: Damaged nozings
-
SLAB ON GROUND
:check: Ventilate the slab (vents + frequent + under DPC)
Wood joists -> :check: Bitumen membrane onto concrete
-
-
-
Heave
-
-
:pencil2: Cracks (vertical/diagonal)
- Bulging/Leaning walls
- Floor deformation
- Drain/Pipes malfunctioning
FLOORS
TIMBER
:explode: Decay of joist -> Vibration
Thermoplastic
tiles
-
:explode: combustion
- dampness through screed
--> alkali vs adhesion
DRAINAGE
:explode: Leaky joints
- Cement joints -> shrink & crack
Movements in the ground
- Obstruction
- Poor ventilation system
