In many of our previous sites covered with granite tiles, the same problem is observed in the open terraces - tightly glued granite tiles, destroyed joints and salts on them.
The lack of a solid foundation leads to many damage to the premises below them, so it is good to think in time to protect against unpleasant moisture and leaks.
As in many of our other sites, the tiles are firmly glued, which allows the application of liquid rubber Hydroflex-Universal directly on them.
We necessarily reinforced all the corners and the floor is polyester canvas.
The oiled waterproofing was laid in 4 layers, and we finished with liquid rubber in beige color:
Liquid rubber on granite - Panagyurishte
Demolition of granite tiles, laying of new leveling screed and waterproofing with liquid rubber
