A boundary retaining wall we have is seeping water in a couple of places at the very bottom only after a downpour. This lasts for days and will eventually dry up with enough time but the water pools near the wall as can be seen in the pic. From what I can tell, the wall is part of a soak-away system and is approximately 30yrs old. It's a double leaf wall? block/concrete internally with Stone on both sides and pilasters along the construction. Should I be concerned or is there anything I can do to remedy this?
