Waterproofing and tiling in commercial kitchens and cool rooms

In commercial kitchens and cool rooms with surfaces to be clad in stone or ceramic, there are considerations, dependent on the area, related to exposure to aggressive media such as for example lactic acid, fatty acids, blood, cleaning materials etc. The choice of waterproofing and installation systems is geared towards chemical exposure. The exposure group according to the ZDB technical sheet (A or C) applicable to the relevant area is to be defined by the planner. In areas exposed to group C, areas with chemical exposure, may only use epoxy resin based waterproofing and installation systems.

The optional use of a conductive strip and conductive lacquer between primer and the waterproofing membrane gives the possibility of a non destructive test for watertightness of the membrane using a spark coil test to DIN 55670 under high voltage. The time consuming and costly testing of the waterproofing measures via a trial fill of the waterproofed area with water can be dispensed with.
