Project Description

Turning up the water tap every morning and obtaining clean water is so self-evident to the 73.000 citizens between Puchheim and Olching in Bavaria, thus no one seriously thinks about where actually the drinking water comes from. The local water utility service provides it from the nearby located elevated drinking water reservoir at the Parsberg close to Puchheim, with a storage volume of 30.000 m³.

To ensure the continued availability of hygienically pure and clean drinking water, the reservoir built in the 70ies, needed an all-round repair. After an operating time of around 35 years, the coating in both water chambers showed extensive hydrolysis damages.

The existing coat was removed from walls and floors and the underground prepared for the new mineral coat. The walls were lined with a microsilica-modified special shotcrete mortar of the product line “MICROTOP“ of KORODUR – in dry mix method in an application thickness of 20 mm. In several working steps the coat was roughly leveled and then mechanically trowelled and smoothed. Also the floor coating in screed procedure was carried out with MICROTOP products.

In total around 18.000 m² wall and flooring areas were coated. The repair measure was supervised by the LGA Nuremberg. Regular control tests confirmed the constantly high and reliable quality of the MICROTOP products in the domain of drinking water.
