In the municipality Klösterle, Austria, the old public swimming pool had to be renovated. Due to the bad condition of the old pool and high renovating costs, a total reconstruction of the swimming pool was necessary.


Because of lesser building and also running costs the municipality decided to build a natural swimming pool where only plants are used for cleaning the water. One of the big benefits of a natural swimming pool is that there is no need to empty it during the winter.

To waterproof the 2.122 m³ natural swimming pool an AGRU FPP pond liner 1.5 mm with a glass fabric inlay was used. It is characterizing by a high flexibility and does not contain any plasticisers. Consequently it perfectly supports the environmental and health benefits of a natural pool.

The installation of the AGRUFLEX pond liner was done by skilled workers of the company IAT. Hot wedge welding as well as extrusion welding was used to ensure the water tightness of the natural pool.
