In the passageway between me and neighbour, I have a shaded flank wall with render plinth that shows evidence of rising damp.

As can be seen in the photo, the damp raises even when there is no standing water in passage. The passage itself is concreted out, (my) wall to (neighbour) wall. On the inside of the house I have damp rising from the floor, some on the wall itself, but most on the chimney breast (which obviously is some distance from the plinth...).
I had a RICS survey done and it was recommended I remove the porous plinth and reduce the ground level in the passage by cutting a gully in the passage next to my wall, and fill it with shingles.
My questions: are there any disadvantages to removing the plinth? Will the gully not soak up all the rain water and hence, increase the damp of the wall? I'd like to avoid lifting all of the concrete in the passage...
