Water ingress through a defective perimeter joint has caused corrosion of steel reinforcement and subsequent spalling of the bearing to this column head. |
|
Deflection in sections of the top deck giving rise to poor falls and ponding that are remote from rainwater outlets. |
|
Chloride concentrations at the base of this ramp (in this case the second ramp from the entrance to a multi-storey car park) have resulted in localised corrosion and spalling. |
|
Rapid corrosion of mild steel balustrade because of chloride contaminated water. |
|
Surface deterioration due to frost damage in an area that is regularly saturated. |
|
Joints at bearing positions are notoriously troublesome. In this case, the bearing of a trimmer beam supporting a double tee deck has failed because of water ingress and corrosion of reinforcement. |
|
Water ingress above this beam/column connection has led to corrosion of reinforcement and spalling of the bearing and reduced support. |
|
The end of a double tee beam shows a halved joint at its bearing end. However, due to movements in the structure the original bearing was compromised and an additional steel beam has been retrofitted to provide adequate support. |
|
A worrying amount of slippage in a beam bearing, coupled with shear cracking. |
|
Profound adhesion failure of a cold-applied waterproofing system probably caused by its application over a contaminated surface or application in unsuitable conditions. |
|
Plastic deformation in asphalt skirting has resulted in the perforation of the asphalt, water logging and plant growth. |
