Water-repellent masonry surfaces, seams, or structure which do not have this water-repellent zone after a while get a crust that is lose requiring preservation of the surface. The danger that arises in this communication increases with the emergence of a phenomenon often encountered in construction practice, when necessary for a while get a crust that is lose requiring preservation of the surface. The danger that arises in this communication increases with the emergence of a phenomenon often encountered in construction practice, when necessary depth of penetration of the solution, calculated on the basis of the absorption capacity of foundations is not reached due to an insufficient number of deposited material. Similar phenomena (crust formation) occurs when the basis is found significant harmful salts. The output from the described "the dilemma" can be only an objective assessment of the situation at the facility based on sound analysis of his condition. In conducting this assessment takes into account such data object, as the natural sciences and engineering, as well as architectural and historical aspects, under which developed a single concept, suitable for all these stages. It is necessary to clearly define the advantages and disadvantages of different concepts to all participants prior to the meeting were aware of the possible consequences.
Fig. 8: Warranty Remmers special planning, sampling using the technique of climbing Mosque Old City / Baku Azerbaijan big help in the decision making process, in this case, on the establishment of water repellency, will released shortly before the publication of this booklet WTA memo entitled "Water-repellent impregnation for natural stone. " Matrix of solutions made up in long-term work is appropriate for the main aspects, including, for a brick foundation, and is recommended for active use since its publication in the early 2009. In his own case basis Brick and conservation / restoration show how multi-faceted aspects to be considered when designing and carrying out the measures. .
