The lake itself had been drained since 2014 but had significant cracking and deterioration on the slab joints. In order to have a succesful restoration, the lake needed to become watertight again. The solution was available using Remmers MB2K waterproofing in conjunction with Waterstop B240 banding. WHY? The existing joint filler material within the lake was bituminous in nature. MB2K adheres excellently to both new and old bitumen coatings, without the need to abrade or mechanically prepare them, a critical advantage in this instance. Removal or the existing damaged fillers would have been a time consuming and costly excercise. Having waterproofed the lake bed and walls, extensive restoration then took place on the stone staircases and planters around the site. Colour matched restoration mortars and Funcosil hydrophobic treatments were used extensively.

Two solutions were used to waterproof the house. The first step was to seal the ground floor base. This was done from above. The base of the house was then waterproofed from the outside. This protects the substrate of the building from moisture on both sides.

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.

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.

The new construction of the underwater world and the large aviary in Luisenpark had to be finished with flat roof structures that would provide reliable waterproofing over the long term. Due to the exposed location and the construction-related moisture load, the flat roofs are the part of the building that is subject to the most stress. A flat roof is exposed not only to rainwater, but also to extreme temperature differences, complex structural-physical interactions and mechanical loads, such as stresses caused by expansion, shrinkage and deflection of the structure. The individuality of the roof construction presented planners and contractors with particular challenges when waterproofing the flat roof construction. But a quick and easy solution was found in the form of MB PUReactive+.

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.

The joints in the concrete sections are subject to continuous movement and so a waterproof and crack bridging system was required. Over 100m of Remmers Flexible bandage B200 was fixed using Epoxy MT 100. The system was over coated in part with Remmers MB 2K.
