The Leobad is a very popular outdoor pool in the region, built in 1988. In January 2017, after 30 years of operation, it was decided to completely renovate the Leobad. Due to the poor subsoil, the existing structures were founded on 611 in-situ concrete driven piles via free-spanning base plates and wall-like beams. Due to the proximity to the neighboring Glems river, 256 tension piles were driven into the ground to secure the pools and the building parts with basements against uplift due to the high groundwater level and a flood that had to be taken into account. As part of the renovation and conversion of the reinforced concrete basins into stainless steel basin constructions, the individual construction phases had to be statically examined and taken into account. To install the stainless steel basins, parts of the channel heads and other fixtures were removed using high-pressure water jets, concrete saws and core drills. Finally, these areas were professionally and permanently re-profiled. The basins were mostly lined with flexible stainless steel cladding. However, self-supporting stainless steel wall elements were also provided to reduce the water surface area. Extensive concrete repair and waterproofing work was also required in the technical basement. Cracks and construction joints were grouted and sealed to prevent the ingress of groundwater. The damaged reinforced concrete walls, floors and ceilings were repaired using concrete technology and then provided with a surface protection system.
