1.500 animals on a total area of approximately 22 hectares - the Augsburg Zoo offers a rich world of discovery, filled with domestic and exotic inhabitants. Among them are about 50 reptiles and amphibians that have been given a new home: The reptile house from the 1970s has been completely demolished and replaced by a modern building, a new place for the animals to call home. The products by the construction chemicals specialist PCI Augsburg GmbH have been relied on not only for the new design of the reptile house, but also for extensive paving on the outside. An area of 200 m2 was to be paved with high-quality concrete blocks. To create a relaxed and modern overall impression, pavers in mixed format were used. Particular challenge: The extremely narrow grout lines of three to four millimetres, planned by the architectural office. This was successfully implemented with the special joint grout Pavifix 1K Extra, which can be elutriated.
