This study evaluated the ceramic tiling in three distinct aspects, impermeabilty to water, water vapor permeability and tensile adhsion strength. For this study, four boxes in concrete structural blocks were built, and each box received a ceramic tiling system. Box 1 reproduced the tradicional system, composed of concrete block, roughcast, plaster, adhsive mortar, tile and grout. In Box 2, the tile was applied in roughcast. In the Box 3 the tile was applied on a rigid waterproofing layer and Box 4 had the ceramic tiling applied directly on the concrete block. As conclusions of this study, all systems presented a good performance regarding the adhseion resistance to traction, with results above the minimum required by standard. The Box 4 presented the biggest adhrence resistance followed by Box 1, Box 2 and Box 3. No system proved effective for watertightness, all showed infiltration points. The system with less water loss was the Box 3, followed by boxes 1, 4 and 2. For testing permeability to water vapour, the boxes were subjected to water vapor during 6 hours, no moisture stain on the outside of the boxes has been verified, however, all registered a temperature increase in the external faces, this increase in temperature was greater the lower was the number of system layers, thus, Box 4 presented the highest mean temperature, followed by Box 2, Box 3 and Box 1. With the results presented in this study , it becomes evidente the need to develop improvements in the performance os the ceramic tiling system, making it na effective system as much as the adhesion, as the watertightness and permeability to water vapor.
