A record-breaking installation in Helsinki

The Olympic Stadium in Helsinki, Finland, the place for the 1952 Summer Olympics, is undergoing major renovation. One very problematic issue was the vertical rainwater pipes in the Olympic Tower (height 72 m). It was prohibited to make any changes to the structure of the tower, and we were not allowed to excavate, so no new pipes could be installed. Besides the actual rainwater pipes, also the outlets and connections were in a very bad shape.

 The Public Works Department contacted Aarsleff Oy and asked if Aarsleff CIPP Lining could be the solution. We were honoured to be asked to work in one of the most well-known landmarks in Helsinki. After careful planning and calculation, Aarsleff Oy came to the conclusion that Aarsleff CIPP Lining could be installed in one 72-metre-long stretch?

The pipelines were cleaned, the side connections were installed, and the liners went up to the top of the tower just like it was planned. Including all the preparation works, the job took only 4 days. So we can say it was a perfect job and a record-breaking installation altogether.
