Facade Protection and Refurbishment

Description

The façade has been heavily soiled over the last 90 years. The sun of the island state in the Caribbean also severely affected the façade. The aim of the restoration was to preserve the original structure and colour scheme. The renewed absorption of water and pollutants should be prevented.

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.

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.

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.

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.

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.

Concrete Protection and Repairs

Description

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.
