【 摘 要 】

One way how to limit the effect of increased moisture on building constructions is the hydrophobization of these constructions or parts thereof. However, hydrophobization protection may be subjected of degradation effects that may reduce its effectiveness. The contribution deals with monitoring the degradation degree of hydrophobization protection of ceramic masonry elements caused by climatic effects. There is a comparison available between accelerated/simulated degradation and non-accelerated real-time degradation. The results are compared with the real capillary absorption of the untreated/non-hydrophobized wall blocks.
