You might form a surface drain in the area of the stone panels in concrete. After removing them If you can slope it along that wall to someplace lower.


I might pour concrete and use a 3 inch piece of abs pipe to get a drain trough shape established. I do not think the volume of water is great. I have had decent luck with some basement waterproofing mediums to get a seal between the new concrete trough and the existing concrete. . The stuff seems to bond to clean surfaces. You do not want any water entering between the pathway and the trough junction.


This approach of course depends on what the physical grades are like around that area. I use a five thousand pound concrete strength as it is waterproof. Looks like a very small volume job.
