Penetration Rate of Various Injection Gels in Dependence on Wetness of Building Materials

Abstract:

Method of using hydroinsulating injection screens during redevelopment of wet masonry is nowadays one of the most efficient methods of treating rising wetness in old but also new buildings. One of the biggest advantages of this method is low damage to the building structure and the possibility of treating the masonry from the inside of the building. One of the aspects that has influence on injection screens functionality is wetness of treated masonry. The main object of this paper is to observe changes in the penetration rate of injection gels in dependence on wetness of building materials.
