“…On the contrary, as also mentioned in the overview and state of the art, the technologies that were the subject of this research have been applied on several sites and their effectiveness has been verified [22,35,36] The different techniques of remediation interventions in this research were chosen mainly because of the complexity of the structure and the surrounding conditions. Grouting was applied in areas where it was not possible to apply stainless-steel plate stamping and undercutting technology.…”

“…It is used worldwide in various types of construction. For example, a study by [22] described the use of diamond wire undercutting technology (the technology is called HIO technology) [23], which dealt with the rehabilitation of a former commercial academy building in Zrenjanin, Serbia, dating back to 1892. The detailed description of the rehabilitation of the building was divided into three steps, which were presented in detail in the paper.…”

Implementing the Technologies of Additional Impermeable Layers in a Building of the Monuments Office (Káčerov Majer) from a Sustainability Point of View

This article presents the results of an experiment that involved applying additional impermeable layers on an historical building in the area of Káčerov Majer. The building showed a high level of waterlogging, which was detected by an initial inspection and subsequent moisture measurements that involved taking a set of measurements and recording the data in a spreadsheet linked to the plan view of the building. Then, a suitable method was devised to prevent rising damp and to assist in drying out the building. Several measurements after the application of remediation interventions were used for this purpose. The interventions, together with a comprehensive restoration, were intended to contribute to the reuse of the building, and thus its sustainability from technical, environmental, functional, and economic points of view. The aim of this research was to demonstrate the degree of effectiveness of undercutting technology in combination with local application of stainless-steel sheet piling and grouting technology, as one example of sustainability, which is a very relevant topic at the moment. These technologies were intended to provide remediation of the building against rising damp which was destructive to the structure. The environment in this building was affected by moisture and was also unhealthy, which made it difficult to use the building. For these reasons, it was necessary to take radical steps, by applying invasive anti-moisture technologies. The appropriateness and effectiveness of the technologies used have been evidenced by the results published in this article that have also been supplemented by photographs before and after the application of the remediation measures. This research demonstrates the effectiveness of the interventions and the need to also implement them on certain selected buildings where there is a high level of dampness causing degradation. From a sustainability point of view, such a step is essential to preserve the life of such structures and their continued use. The results of this research clearly demonstrate the appropriateness of comprehensive restoration of selected historical buildings, complemented by invasive damp-proofing interventions, as one of the important aspects of the sustainability of deteriorating monuments, whose numbers are constantly increasing.

“…During Experiment 2 samples were placed into a water tank to conduct long-term water absorption test with full immersion according to EN 12087:2013. As required by this standard, water absorption should be determined as a percentage by volume (V/V %) or by weight (m/w %) after 28 days of water immersion compared to air-dry condition [22]. However; the date of saturation was unknown, and it was also important to document the evolution of water absorption process in time.…”

Nanotechnology-based thermal insulation materials have appeared in building industry in the last two decades. Among them thermal insulating coatings consisted of vacuum-hollow nano-ceramic microspheres are the subjects of most professional discussion. Most studies about these coatings focus only on examination of thermodynamic properties, because there is still no consensus in academic circles about thermodynamic processes inside nano-ceramic coatings. These professional discussions distract attention from other unknown but also important material properties, like behavior by contact with moisture. This paper summarizes the results of moisture behavior tests with nano-ceramic thermal insulation coatings which were conducted to determine the time trend of water absorption, as well as volume, mass and thermal insulation quality changes caused by increasing moisture content. Analyzing the results mathematical connections were found to describe the relation between water content, dimensional and thermal conductivity changes.

“…The most effective method reducing the water flux is prevention through the physical separation of building materials from the ground moisture and salts by the use of a traditional damp-proof course. An impermeable barrier such as plastic, glazed brick, or bitumen is typically used [45]. However, using such protection measures in historical masonry is mostly not feasible.…”

Salt damage can affect the service life of numerous building structures, both historical and contemporary, in a significant way. In this review, various damage mechanisms to porous building materials induced by salt action are analyzed. The importance of pretreatment investigations is discussed as well; in combination with the knowledge of salt and moisture transport mechanisms they can give useful indications regarding treatment options. The methods of salt damage treatment are assessed then, including both passive techniques based on environmental control, reduction of water transport, or conversion to less soluble salts and active procedures resulting in the removal of salts from deterioration zones. It is concluded that cellulose can still be considered as the favorite material presently used in desalination poultices but hydrophilic mineral wool can serve as its prospective alternative in future applications. Another important cause of building pathologies is the rising damp and, in this phenomenon, it is particularly severe considering the presence of salts in water. The treatment of rising damp in historic building walls is a very complex procedure and at Laboratory of Building Physics (LFC-FEUP) a wall base hygroregulated ventilation system was developed and patented.
