Brick rehabilitation on the construction site
Tadeusz Kosciuszko University of Kraków, Poland

Ammerbuch, February 2013. Currently, around 17 buildings of the Tadeusz Kosciuszko University of Technology in the Polish Kraków are being rehabilitated. By doing so, the special building material systems for rehabilitation of brick and masonry of the epasit company from the Swabian Ammerbuch, prove their worth.

Owners of historical brick buildings, curators of monuments and masons in the entire world have to decide on how to restore historical buildings in the correct way. The brick rehabilitation system offers you a permanent and effective solution, because its components are exactly harmonized and can be easily applied.

Former barracks in a delapidated condition

In 2009, the rehabilitation of further sections of the Institute of Technology of Kraków in Southern Poland, has been decided. The building constructed between 1872 and 1878 has been used for a long time by the Polish and Russian army and the structure suffered for decades. In the basements, as well as on the ground floor, large areas of the masonry were damaged by salt and showed a particularly high concentration of nitrate. For a long time, the finishes of the interior walls have been destroyed by salts and brick facades and brick walls have been heavily damaged by environmental influences.

Rehabilitation of the interiors

In spring 2010, the dismantling works started and all ailing finishes of interior walls were removed. Because the salination extended deeply into the masonry, the responsible persons opted for a rehabilitation using a plaster system which withstands special stress. It meets all requirements of the preservation of monuments as well as of the DIN EN 998-1 and was awarded as the first renovation plaster system the WTA certificate. For the construction of the walls, special plasters such as 'MineralDicht sperr' and '5in1' as well as the rehabilitation system 'Mineral SanoPro' from epasit was used.

Brick facades get rehabilitated

In the years 2011 and 2012 the masons mainly devoted themselves to the restoration of the brick facades. Because of the aggressive environmental pollution in the Polish coal-mining district these have been massively damaged. The masons tried to remove the worst damages by exchanging the bricks, which, however, turned out to be very complex and expensive. Further, based on the motto 'restore instead of replace' the brick rehabilitation system ZRS was convincing. In the end, the skilful combination of the existing substance and replenishments appear much more natural. It gives the brick walls of the Institute of Technology of Kraków a fresh new look and preserves at the same time the original character.

Brick rehabilitation: System application instead of isolated application

Firstly, all surfaces were cleaned mechanically in order to remove all disintegrated particles and undermined joints have been raked out. Secondly, the masons saturated the bricks with the mineral hardener 'sv', with which the stone structure of the upper layer could be restabilised. Larger fragments have been remodelled with brick rehabilitation mortar mixed in the original colour. The thoroughly cleaned joints were filled by the masons with the rehabilitation pointing mortar 'fsm', which was also coloured according to the sample. Finally, the outer facade surfaces were permanently protected from rain and environmental influences with the waterproofing 'ip237'.

Fragments on door frames rehabilitated

The door portals and frames in the interior of the buildings, too, were partly affected by disintegration. The missing structure was replaced by components of the sandstone rehabilitation system S3 from epasit, which were adapted in colour and structure to the original. For this, the portals in question have firstly been cleaned. Secondly, the masons coated them with a bonding slurry which is easy to apply. The fine sandstone rehabilitation mortar was mixed with 'fx Fixal' and applied on the still wet bonding slurry. Thanks to the system S3 the door portals are now again in an optimal condition.

Brick vaults

In the basement rooms and corridors of the Tadeusz Kosciuszko University of Technology in Kraków, extensive brick surfaces had to be rehabilitated as well. On surfaces especially affected by salt, the long-term proven renovation plaster, 'MineralSanoPro' was applied and integrated in an optically skilled way into the brickface. After rehabilitation, the basement rooms will be utilised as offices, laboratories, server and storage rooms as well as a cafeteria. This utilization requires a high standard regarding room temperatures, humidity of the air and healthy climate. In this case the mineral calcium silicate boards 'epatherm' and the climatic plaster 'ekp' have been used, so that the relative humidity of the air levelled out at a constant standard of approx. 60 per cent even without an expensive primary energy - a cost-effective and nonpolluting solution.
