 For the owners of multi-storey car parks and other major structures, this is a major dilemma, since it is assumed that both options will inevitably be costly, time-consuming and disruptive. The owners at Karihaugen BRL and Ellingsrud BRL recently faced this issue, but found a better than expected result.
On this site near Oslo, the five multi-storey car parks have been extensively used by residents for over 30 years. In addition to general disrepair, there was evidence of rebar corrosion within the floor slabs and rapid deterioration on the external facades.

 A new lease of life for Skårertoppen BBL’s Multi-Storey Car Park: Skårertoppen Co-operative Housing Association have always offered good parking facilities for residents, but in Winter 2007 it became clear that refurbishment and repairs were urgently needed to the multi-storey structure. The car park was run down and showing extensive rebar corrosion in the concrete deck slabs and columns in the intermediary levels. This in turn was creating safety concerns and risk to users.

 The aging car park of Bjørnekollen BRL suffered from widespread rebar corrosion which lead to reduced load capability. A well known player in this market recommended demolition of the old car park and then to build a new. With Cathodic Protection (CP), carbon fiber reinforcement, some creativity and a lot of good cooperation the owner saved more than 50% of the cost related to building a new. Of course the repair-project took only a fraction of the time demolition + newbuild would have taken. Now the entire car park can agin be used, including the top-deck that was previously closed due to load-restrictions. Remote monitoring with yearly status reports from the CP installation documents corrosion free concrete in the coming years. |

 "Driving to the office" takes on a whole new meaning when it comes to concrete corrosion in Multi Storey Car Parks. Surprisingly, most MSCPs are built like office buildings, without any protection on the floor slabs, and yet they are intended for use by cars. Of course this means that when cars drive into the "office building" (MSCP) they often bring in de-icing salts from the roads, causing the rapid development of extensive rebar corrosion which reduces both the carrying capacity and lifespan of the MSCP.

This article about the possibility of saving money with monitoring was printed in USA Today, read entire article here  By Alan Levin, USA TODAY MINNEAPOLIS — The disaster caused by the collapse of one of this city's highway bridges points to the need for better technologies to inspect bridges, but states have been slow to spend money on the new methods, national safety and engineering experts said Monday. Dozens of new technologies can help monitor bridges: X-ray machines that can spot hidden cracks in girders, computerized monitors that track minute changes in stresses on steel beams, and sensors embedded in concrete that track corrosion of steel reinforcing beams. |

 The Silver Jubilee Bridge over the River Mersey, between Runcorn and Widnes in the UK, carries over 80,000 vehicles every day. Not only is the bridge in constant use as a busy highway, but it’s also an important heritage listed structure and is currently undergoing necessary refurbishment. In order to halt the rebar corrosion in the concrete deck slab, Protector's CASSETTE CP system is being installed on the soffits. This innovative, patented “clamp on” system includes a Titanium - Glasswool-and Glassfibre cassette system and is first installed as a trial on this structure and will be monitored and adjusted remotely.
The on-site installation is being carried out by Balvac LTD, Redhill, Surrey, England. The project consultant is Mott MacDonald and the client is Halton Borough Council.

 Getting experience from the players in the concrete repair business through to the new-build business has often proved difficult. This article in the Norwegian newspaper Dagbladet dicusses how such experience may have been ignored even for prestige projects such as the new opera in Oslo.

 As part of a total refurbishment solution for Vestskrenten BSE’s buildings, two large roofs have been treated with the innovative PPD system to produce seamless, non-combustable, reinforced and flexible "new" roofs.
The work has been carried out by Protector AS who are involved in the repair and upgrading of all exposed concrete (e.g. balconies, terraces, facades and garages) to new standards by use of AHEAD repair and protection materials. In order to renovate the roofs, they first had all the old felt and insulation removed which was replaced by the PPD system. See video . |

 Around the world, thousands of reinforced concrete structures are becoming critically damaged due to corrosion and poor or incorrect maintenance. This corrosion - often caused through salt ingress can render the structure to be unsafe, eventually becoming a danger to users. Often the phenomenon is invisible since the corrosion happens inside the concrete body and it is not recognised by the owners until it has reached a very advanced state. By these stages, it will require specialist knowledge to reveal the actual condition of the structure followed by expensive reparation work. All too frequently, the extreme damage is misunderstood by owners and consultants, and costly mistakes are made concerning appropriate treatments. |
