Building defects database - Multi-storey car park

Record details

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.
