Rehabilitation of Historical Drainage and Ventilation System in the Prague Castle Area

The paper deals with a structural survey of the historic drainage and ventilation system discovered recently in the Prague Castle area. Based on in-situ inspection the remedial works in the context of historic importance of the area are presented. The experimental testing is used for the assessment of the efficiency of remedial technologies, but also for a deeper investigation of moisture transport phenomena in heterogeneous materials. The data collected for the investigated aspects should allow foresight of the behavior of existing structures providing damage prediction models and help in the design of remedial measures.
