Experimental testing of hydroinsulating injection screens efficiency in dependance on properties of building materials
Červenka, Martin ; Černý, Vít (referee) ; Drochytka, Rostislav (advisor)
The most of the buildings are almost always faced with moisture in our climate. In the past, the humidity was reduced and conducted only by mechanical methods. Over time, chemical wet masonry method also known as chemical infusion curtain was invented and introduced into practice. This method involves the creation of boreholes at a selected height of humid masonry. These boreholes are impregnated with special solutions. These solutions in humid masonry fill pores in the field of boreholes and thanks to this subsequence the monolithic waterproofing curtain is created. The objective of this work is to determine the methodology for verifying effectiveness of various types of waterproofing injection curtains depending on the properties of the various types of building materials.

Gel infusion screen system for additional waterproofing of various types of masonry with share of secondary raw materials
Melichar, Jindřich ; Klečka,, Tomáš (referee) ; Dohnálek,, Pavel (referee) ; Novotný, Miloslav (referee) ; Drochytka, Rostislav (advisor)
Virtually any construction project in our climate zone is facing some form of moisture. Older and historical buildings are mostly affected by the negative impact of water. Previously, the additional reduction of the moisture was executed only by mechanical methods, pushing insulating sheets or breaking through and cutting of masonry. Over time chemical methods were also invented, which are compared to the mechanical considerably simpler and user friendly applications to statics of treated buildings, making them ideal for the treatment of historical buildings or buildings that would not bear significant disruption. The main principle of chemical methods of redevelopment of wet masonry is the application of special material into the line of drilled holes with a given pitch. Subsequent penetration of the grouting material is believed to intersect an arc of individual drill holes, and thus to create so-called grout curtain that prevents the accumulation of water above it. Injection material may also contain a proportion of secondary raw materials, thereby reducing the influence of the impact of production on the environment. Efficiency infusion materials in masonry affected by many factors, such as temperature, humidity, or the type of material treated. It is also an important factor to determine the effectiveness of the remediation of the material, proving its ability to penetrate the building material by identifying its presence in it.

Determination of waterproofing screens efficiency in various types of building materials exposed to capillary wetness
Červenka, Martin ; Dohnálek,, Pavel (referee) ; Drochytka, Rostislav (advisor)
Increased moisture of masonry occurs mainly in older buildings. In some cases these problems arise even in new buildings. This issue should be properly treated and process of rehabilitation of the building must be executed. Humid walls can be treated by chemical injections, which is nowadays quite extensive and widely used method. Unlike mechanical methods humid walls in the implementation of chemical grouting does not need a major redesign and thus is friendly to the construction of the object. The main objective of this thesis is to establish a methodology for testing the injection materials, which will include a selection of ideal injection gel.

Draft Curtains new Ways of Waterproofing and Assessment Methodologies
Miková, Lenka ; Dohnálek,, Pavel (referee) ; Drochytka, Rostislav (advisor)
Gel injections are progressive and more and more widespread technology for wet masonry rehabilitation, which finds its use due to working simplicity, and final effectiveness. In their application is not necessary to use strong destructive methods on construction and functionality of the final waterproofing is at a very high level. But the actual application of these technologies has technological limitations, and therefore arose in construction practice need of research new gel infusion with additional parameters and added functionality. Given the lack of a uniform methodology for such complex research process, the main aim of this thesis is proposal for methodological process for the research of new gel materials, and their later efficiency verification in the construction practice.
