Building Waterpoofing and Refurbishment, Facade Protection and Refurbishment, Coating for Windows and Wood Elements

Description

The buildings of "New Holland" have been restored several times over the years and have been repeatedly supplemented with new buildings and extensions. All buildings were damaged inside as well as on the facade and roof. The brick facades in particular, which were heavily soaked through, posed a major problem. In addition, damage to the masonry and the cladding of the plinths was detected. During the restoration of the brick masonry, the varying condition as well as the heterogeneous nature proved to be a particular challenge. There was also high salt content, which could be damaging to the building and therefore had to be reduced. Finally, the aim was to achieve the most harmonious possible colour matching of the stone surfaces.

Facade Protection and Refurbishment

Description

The microbiological load of the building bricks and the high mobility of the stored hygroscopic magnesium sulphates required adequate moisture protection in the area of the paint setting systems. Due to the high salt loads, a hydrophobic impregnation was ruled out. In order to minimize the water ingress via the facade surface and the associated damage processes, a silicone resin paint was selected.

Facade Protection and Refurbishment, Concrete Protection and Repairs

Description

The neo-baroque parish church of St. Martinus was built as a skeleton structure in a concrete / reinforced concrete construction. The exterior façade showed cracks in the wall shell, plaster and concrete. In addition, cavities, shearing off and spalling of concrete mouldings as well as iron corrosion were found. For a long-term restoration and preservation of the building, the concrete shell was partially replaced by a brick shell. In the course of the renovation, all corroded iron structures were also treated and corrosion protection was applied. Cracks and crevices were filled and decorative elements were preserved or restored. The plaster surfaces were reconstructed according to historical models. They were given a completely new coat of paint for a uniform overall appearance.

Concrete Protection and Repairs, Building Waterpoofing and Refurbishment

Description

The pool is permanently exposed to positive and negative water pollution. It was therefore important that an expansion zone remains in the middle of the joint seal, which allows the structure to work and provides an optimal surface. The joints should still be reliably sealed. Both the crack repair and the concrete repair were carried out in accordance with the classic procedure in accordance with the repair guidelines, in which cracks are closed by injecting epoxy or polyurethane resin using a drill packer. The concrete surfaces in particular had to be protected against chemical attack, especially against the high ammonium pollution from the connected meat industry.

Facade Protection and Refurbishment

Description

The concrete surfaces of the balcony parapets were repaired and a surface protection was applied. This has a hardening effect, is alkali-resistant, open to water vapour diffusion and water-repellent. The prepared substrate was then painted with a mineral paint in accordance with a specified colour concept. In order to implement this individual concept, a special colour shade was produced that exactly met the customer's requirements. The balcony fronts were replaced and covered with a metal sheet.

Concrete Protection and Repairs, Facade Protection and Refurbishment

Description

One part of the two-year renovation of the South Bank Centre was a large-scale concrete restoration of the exposed concrete surfaces in the interior of the world-famous art rooms. The walls and ceilings in the Queen Elizabeth Hall, Hayward Gallery and Purcell Room were restored to their original state by means of colour matching. In order to clean the surface from dirt, the room was prepared under strict observation of the room temperature and relative humidity. The film-forming peel-off paste Arte Mundit was applied in the required thickness to remove the surface impurities. This created a cleaner, brighter environment.

Facade Protection and Refurbishment

Description

On the façade surfaces of Kaispeicher A, there was a lot of efflorescence and lime aging, both signs of penetrating moisture. The damage patterns indicated a lack of frost resistance as well as no protection against driving rain. The listed façade required extensive frost and moisture protection, but was not allowed to undergo any visual changes.

Floor Coatings

Description

In order to facilitate orientation around the store, a coloured customer guidance system was to be installed on a floor area of over 1,800 m² to the respective product displays. With the colour-contrasting "lane", individual departments in the supermarket were highlighted to help guide the customer through the market. This also allowed the shopping trolleys to glide much more quietly than they would over tiled floor.

Description

In the course of the regular test inspection in accordance with DIN 1076, the chloride concentration and the carbonation depth of the structural concrete was determined using a mobile bridge inspection device on an area of approx. 12,000m², in addition to the tests prescribed by the standard. Furthermore a random measurement of the concrete cover as well as an endoscopy of the tendon cladding tubes were carried out via the ventilation tubes. The result: urgent need for renovation.

Building Waterpoofing and Refurbishment, Facade Protection and Refurbishment

Description

The restoration of the building, which is over one hundred years old, was a complex task. The facade first had to be cleaned with special product due to the high degree of contamination with heavy efflorescence and sintering, The damaged joints were then repaired. The white natural stone elements of the façade were desalinated with compresses and then re-profiled and supplemented. This was followed by stone consolidation and hydrophobing. A mineral sealing was applied in the base area, which was finished with a new layer of plaster. Therefore protecting the building from further moisture ingress.

Concrete Protection and Repairs

Description

The reinforcement had too little concrete coverage and the quality of the concrete also varied. This led to corrosion damage and concrete spalling. Since 2005, stricter regulations of the food law and hygiene regulations have been in force, which had to be observed. This meant that all surfaces had to be cleaned with a high-pressure cleaner at 500 bar water pressure in order to reach solid ground and to determine the true extent of the damage.

Considerable damage was visible at digester No. 4 as a result of a biogenic sulphuric acid attack (BSK attack) to the concrete. The structural condition analysis revealed advanced damage to the concrete surface. In some areas it showed indentations of up to 5 cm. The dome area was also to be given a new coating.
