1. Introduction
Tampere Swimming Centre, completed in 1979, has three separate swimming pools: the main pool, a children’s pool and a so-called paddling pool, see Fig. 1. The main pool is 50 m long and has eight lanes. It can also be divided into two shorter pools with a hydraulic lift bridge. The extension completed in 2007 contains a 25 m swimming pool and a diving pool. The major renovation of the Tampere Swimming Centre started in May 2013. It involved improving the HVAC systems and water treatment as well as some new space arrangements. All changing rooms and showers as well as surfaces of the pool area were also renovated. After the renewal of the hydraulic lift bridge it is also possible to stage official 25 m swimming competitions. The extension remains as it is. Disintegration of concrete due to alkali–aggregate reaction (AAR) was detected in the concrete structures of the swimming pools during the renovation. None of the pools had ever been waterproofed. The propagation of AAR requires ahigh moisture content of concrete. The warm water (+24 8C) in the pools had kept the moisture content of the structural concrete high since 1979.
