Jayne...This looks a exterior drainage issue. What is on the other side of this wall. Is it an exterior wall? If so some photos of the exterior would help.

These are exterior and interior walls. A fault in the construction that we are stuck with so need to try to work around it and disguise it. They fix it and it comes back. We've tried to waterproof it with stuff from the states but it just didn't work. That's Egypt ! Lol thought to make the wall an a cant wall with some type of slate or stone and line the rest of the walls with something. How high? Not a clue, my eye is not picturing something attractive...

This is our view so don't want to leave...hope to retire here. Lol

Jayne- How is the water getting into the wall? What a beautiful view!

Well, first the original foundation was not sealed properly so the water from the Red Sea is keeping the lower levels moist. Only way to fix it is to tear down the whole complex. Then we are in a duplex type of villa and the neighbors had a bad leak upstairs and it affected my bedroom flooring and my downstairs living room ceiling. These will be repaired after it dries out this summer which leaves us with the lower walls downstairs. We are thinking maybe slate tiles two rows up from base all around the rooms?

Here is the problem you will face: what ever you "attach" to the walls, will come off. Right now the paint is bubbling and about to start peeling. Ugly but fixable. If you start adding things like mortar, brick or stone, all of that will begin to fall off the wall as well. It will be more expensive to install and more expensive to fix later on.

The question becomes, which would you rather "fix" - bubbled paint or falling slate.

What about trying to seal it with basement paint again? I can't imagine having to break and fix every year. Now I'm crazy, thinking about wood frames and putting up a chair rail. Oh btw, there are tiles along the floor and they have stayed secure? The walls are cement....
