The organoleptic examination proves a significant degree of structural disintegration of concrete - some loosely embedded aggregate grains easily fall out when touched. The vertical range of the above changes includes a zone up to approx. 60 cm above the wastewater level, i.e. thea zone of fluctuations in the level of wastewater and a spray-gas zone. In the case of the tank 01/1 this means the full usable height of the tank, which may mean in the longer term the propagation of damage to the lower surface of the roof.
