tile over concrete patio that meets back of stucco house

[amh56]

I have a stucco over frame house built in the 70's. A simple concrete slab abuts the back. There is a 'space' between the bottom of the stucco'd wall and the concrete. Would I be able to lay tile on the concrete without creating a moisture wicking problem? Or do I have to have the concrete removed and start over. Obviously, for costs sake, I don't want to do that but I also don't want to wreck the walls of my house.

As long as the tile does not touch the bottom of the stucco, you have done nothing to change the current status. If the present concrete does not to uch the stucco, as long as you keep the tile 1/4 inch away from the stucco, unless you have violent weather, the water on the top of the stucco will n ot touch the house except where the concrete slab touches the house, and yo u don't seem to be worried about that.
