By using water-repellent sealants, the flexible sandstone can also be used in bathrooms and wet rooms. This option is particularly interesting for spas, saunas and similar facilities. The warm and pleasant look of the sandstone is ideal for applications in these areas, as it is here that the customer expects a pleasant atmosphere. In addition, the material is also due to its natural roughness for the clothing of floor surfaces in such objects particularly suitable because high demands are placed on the slip resistance in the rule.
As part of the interior design essential elements can be dressed with flexible sandstone. Here are the application possibilities, whether in office and administration, hotel and catering, but also in the private living area hardly limits.
So it is e.g. possible in representative reception areas (bank, office, hotel, etc.) to design the counter, advertising or company carriers, individual mobile items up to accessories such as planters and lamp bodies with this material. For the private sector, these applications can be based on typical elements such as fireplaces, wall panels (eg also backlit) u. a. m. translate.
Picture: Clothing of a wooden material board, thickness approx. 4 cm with flexible sandstone, design Königstein. It creates the appearance of a massive sandstone slab. The design with twig and spring so creates an effective and very individual Ausstattungsaccsessoir.
Our products made of flexible sandstone design are characterized as wall cladding by high quality, durability and exceptional appearance. It combines essential material properties of natural sandstone with those of other flexible wall coverings.
The play of natural shades (no added color pigments) gives the material a pleasant look and creates a cozy atmosphere in the room. Structure, composition and low weight and minimal construction heights give the material high flexibility and thus open up the widest possible application and processing possibilities, whereas solid sandstone here often technical or natural limits are set.
The processing is easily possible on all substrates, concrete and render surfaces, drywall, wood and wood composites, plastic and even metal surfaces. Also on curved surfaces, z. As columns, or irregular substrates, our products can be used.
Large-area processing without joints or a wide variety of blanks and processing with a joint pattern makes it possible to achieve a wide variety of design effects that make the respective room unmistakable. Thus, the individual wishes of the respective client can be taken into account to a special degree.
In the period of promoterism and earlier epochs, facades, especially in the representative ground floor zones of residential and commercial buildings, were often very elaborately made of solid natural stone. This can be seen in profilings, grooves, segmental arches, keystones, etc., which have been executed as elaborate stone carvings. At the present time, the production of such a façade or even just some of the elements mentioned would be extremely cost-intensive.
If such buildings are rehabilitated, these facade parts are usually renewed.
In the present case, a Wilhelminian property in the Dresden Neustadt, the condition of the ground floor facade was particularly bad. Many parts were heavily weathered, so that the strength of the sandstone was severely impaired. Some parts had been broken out, others improperly repaired. Likewise, several old layers of paint were found. Under these circumstances, the facade would have been completely renewed. However, this was not feasible for the owner for cost reasons.
Therefore, in cooperation with the responsible architect and in agreement with the competent monument protection authority, the following solution was developed and implemented.
First, heavily damaged parts were removed. The missing and damaged parts were restored with suitable mortar in the original form. Old layers of paint have been removed. Subsequently, the entire facade was covered with flexible sandstone component by component.
The façade today appears in its old glory and is virtually indistinguishable in appearance and quality from the natural stone facades of the neighboring buildings.
Plaster facade or thermal insulation composite system with reinforcing layer
On plaster surfaces or thermal insulation composite system with reinforcement, the flexible sandstone is bonded directly. Dispersion adhesives or mineral adhesives that are suitable for outdoor use are used. So even large areas can be made in sandstone. Through different installation techniques (with or without joint pattern) different appearances are achieved.
In a facade cladding without joint pattern, the surface appears as a continuous sandstone slab. However, for this type of installation, the area should not be too large, as even massive stone slabs can only be produced up to a certain size. Too large areas are therefore unnatural.
For processing with the joint image, the desired formats must be cut beforehand. The laying on the facade is then done in grid or bandage, so as to produce certain optical effects, such. B. as facade cladding with large-scale natural stone masonry.
The image example shows an industrial building in Thuringia. Here formats of 85×55 cm were processed with horizontal grain in the bandage. The bonding took place on impact. The butt joints were then tightened, so that very narrow chamfered fugue and thus a very fine joint pattern was created.
Plaster facade with horizontal grooves as optical structure
In this facade cladding on a detached house in Dresden, a plaster facade, which was additionally structured by horizontal grooves, had to be subsequently covered with flexible sandstone. The processing takes place here just as in a conventional plaster facade, but for this application, the necessary formats in height previously cut so that the area between the grooves plus the groove depth is completely covered. The horizontal impact between the formats lies in the middle of the groove.
The format length is freely selectable in this case. Here, the lengths were divided in such a way that the optical impression of a bandage was created again by half-format offset. The vertical joints were designed as a fine Keilfugen and thus come back significantly compared to the strong horizontal grooves.
This example shows a facade cladding of an institute building in Potsdam. The main view consists of a ventilated curtain wall made of solid sandstone slabs (Oberkirchner Sandstein). The problem was that the massive stone slabs in the attic area could not be processed from static. Nevertheless, in order to be able to continue the appearance of the sandstone facade in the attic area, the following construction was chosen.
As curtain elements aluminum cassettes were made in the dimensions of the sandstone slabs. This was then covered with flexible sandstone over the entire surface including the peripheral edges in the appearance of Oberkirchner sandstone.
The challenge for us was to recreate this look as true to the original as possible, so that there was no disruption of the overall impression. In close cooperation with the client and through the great commitment of our sample production, we have succeeded, as we find, in an impressive manner, as the result shows.
Flexible sandstone as a timeless architecture material
Sandstone is a unique natural product. Sandstein Concept’s flexible sandstone products are made from globally imported natural sands in manufactory work in the design of nature. Sandstone surfaces are thus produced as veneer in the form of sheet goods or as a tile in many formats. Interiors, wellness areas and facades are equipped with this exclusive sandstone surface. Flexible sandstone has a sublime, natural and timeless appeal. A large number of designs, some of which are confusingly similar to some of the world’s sandstones, give the architect design freedom in a comprehensive color spectrum.
