Damp in wall caused by concrete slope

[meduza]

I'm currently suffering with an external damp issue which is being caused by a concrete slope which runs parallel to some stairs. (see attached photo). Everytime it rains, rainwater runs down the slope and into the wall.
It seems as though the previous owners had tried to remedy it by applying some bitumen paint to the lower section of the wall. However, I'm looking for a solution which prevents water getting close to the wall. Any ideas would be greatly appreciated.

Could possibly be easier to build a small roof over this area.

Just re-coat the wall properly.

And sort out some stainless steel screws

Thanks for your response. Unfortunately it’s not possible to do build a roof over the area.

Thanks for your response. Do you mean re-coating the bottom of the wall with bitumen paint? I definitely also need to replace the flue guard!
