Swimming pool – concrete wall cracking/deterioration
-
Soil subsidence under/against pool
-
Poor design or installation
-
Changes in soil moisture or groundwater levels
Swimming pool vinyl liner ripples/distortion/degradation
-
Liner not installed correctly
-
Age/degradation - shrinkage, wrinkling
-
Corroded galvanised steel supports
Crack(s) in foundation walls
-
Settlement due to ground subsidence or shrinking/expansion of clay soils
-
Insufficient depth of footings for ground conditions
-
Poor quality concrete or insufficient concrete cover of the reinforcing steel resulting in corrosion of the reinforcing causing the concrete to crack
-
Frost damage – water that gets into small cracks in concrete expands as it freezes, enlarging the cracks
-
The wall has been undermined by basement excavations
Rust stains on concrete/concrete block foundation walls
-
Poor quality concrete absorbing water that rusts the reinforcing, which in turns causes the concrete to spall or crack, allowing in more water
-
The reinforcing was installed too close to the outer surface of the concrete
-
The building is close to the sea and the concrete is of poorer quality
-
The concrete is low strength
-
Moisture is rising up from the ground
Rusting flashings and metal components
-
Air-borne salt, dust or dirt accumulating under flashings and metal components
-
Zinc (galvanizing) or aluminium/zinc or zinc/aluminiuim alloy coating has been scratched or eroded, exposing steel
-
Acidic leachate from cedar or H4-treated timber (containing copper-based preservatives)
Steel deck beams – rusting
-
Exposure to air-borne salt, dust or dirt; trapped moisture and dirt
Steel deck posts – rusting
-
Inadequate corrosion treatment
-
Severe sea spray/coastal environment
-
Trapped moisture
Veranda beams and posts – rusting of steel
-
Insufficient corrosion protection for the environment
-
Lack of cleaning and/or coating maintenance on painted non-galvanised beams/posts
-
Erosion of galvanising
Timber or steel window – cracked or loose putty
-
Putty is not protected by paint and has dried out
-
The glazing rebate was not primed before the glass was installed
Timber and steel windows – paint failure: peeling/flaking
-
Thermal expansion and contraction of the frame
-
Loss of adhesion due to excess moisture in frame
-
Poor initial substrate preparation
-
water-based enamel paint applied over water-based (acrylic) paint
-
The surface was damp or dirty when painted
-
A dark paint colour has been used
-
There has been timber swelling/shrinkage caused by moisture absorption into the timber end grain if the joints were inadequately primed before installation
Steel windows – rusted frames
-
Exposure to air-borne salt, dust or dirt; atmospheric moisture
-
Galvanised protective coating (if galvanised) has eroded
-
A deteriorated paint finish has exposed the metal
Steel windows – paint failure: peeling/flaking
-
Corrosion caused by moisture getting under the paint
