Pier Road Multi-Storey Car Park (MSCP) in St Helier, Jersey underwent a 16-week refurbishment with improvements to the concrete floors, cleaning, repairs and painting of the stairwell and walls. The size of parking bays was increased and safety fences replaced around the car park flooring.
Due to the high levels of chloride and carbon penetration into the structure, as well as failure of movement joints, these repairs were essential in order to keep one of Jersey's largest car parks in working order.
Concrete decay is caused by carbonation. Carbon dioxide in the atmosphere reduces the alkaline content within the concrete. This leads to the increased likelihood that the steel within the concrete will be vulnerable to water attack and oxidisation, leading to steel corrosion and cracking of the concrete.
To protect against steel corrosion and concrete cracking, over 4000 litres of Hydron’s Nu-Guard Anti-Carbonation Coating System were supplied to Pier Road Multi-Storey Car Park. The works were carried out by Concrete Repairs Ltd.
In addition, the stairwells had the extra protection of Nu-Guard AG Clear, which is a clear anti-graffiti paint. If graffiti is applied to Nu-Guard AG Clear, removal can be achieved very easily using warm soapy water.
