The Archabbey of pannonhalma

One of Hungary’s most emblematical monuments, declared a World Heritage Site by UNESCO in 1996, is under continuous renovation.

Since 1992, work has mostly been carried out using Weber systems.

Issues & Stakes

Since the first Benedictine monks settled down and established the monastery at Saint-Martin Hill, next to the current Archabbey of Pannonhalma, the Archabbey has been the property of the Order of Saint Benedict, and today forms the second largest territorial abbey in the world. The Hungarian congregation has 5 monasteries and 36 churches. 1000 years after its foundation, in 1996 the Archabbey was declared a World Heritage Site by UNESCO, with more than 200,000 visitors per year.
With more than 50,000 m2 of façade and due to the permanent constructions, various architectural and art styles can be observed on the buildings. Gothic, renaissance, baroque, rococo, classicist and modernist styles can be found side-by-side on various building types.
For the above-mentioned reasons, systematic façade renovations started in 1992 using weber-terranova systems, and works are still ongoing. The most important principle of the renovation is to be “historical and contemporary” at the same time.

Achievements

Weber is involved mainly due to its high quality service, not due to price competition, and is able to offer complex solutions for every architectural style and for every type of building. During the whole process of the works, Weber’s personal presence was decisive, as well as its collaboration on daily tasks with the owner, authorities, architects and contractors, helping them with wall analysis and technical recommendations to find a suitable solution for the actual problem. Due to the diversity of architectural styles the tasks were also very complex - e.g. wet/damp walls, renders, paints from the Middle Ages, special cement-free base coat and mineral renders. Unique solutions were required. Some of the renovation products and systems applied includes both cement-based damp proofing and renovation mortar systems, especially designed mineral renders  and cement-free, lime-trass-based traditional mortars for the renovation of dry, non-damp walls. The finish has been coloured with a Silicate paint.

Some of the renovation products and systems applied:- weber.san plus system: Cement-based damp proofing, renovation mortar system for plinths, with splatter coat and porous base coat. - weber.san presto system: white-coloured, cement-based damp proofing, renovation mortar system with splatter coat, porous base coat and smoothing mortar.- weber KPS system: cement-based, traditional mortar system for renovation of dry, non-damp walls, with splatter coat, base coat, and smoothing mortar. - weber terramin: special structured mineral render developed exclusively for this project. - weber renotrass system: cement-free, lime-trass-based, traditional mortar system for renovation of dry, non-damp walls, with splatter coat, base coat, and smoothing mortar. - weber F 100 silicate paint
