Question Retaining wall leaking drainage rocks

The retaining wall in my yard started leaking rocks from two of the drainage pipes last time it rained hard. I have no doubt the wall was built well, but it is at least 40 years old. Is this a big problem? Should I do anything about it to prevent further issues?

Welcome to the forums.

Can you give us some pictures from further away?

There must be tremendous water movement behind the wall, to push that many rocks through the weep holes. Why not try forcing some rigid wire mesh stops into the weep holes, formed to match the pipe diameter with a tight fit?

@StickShift - sure. I will try to take some tomorrow. Anything in particular that would be helpful to see?

@BridgeMan45 - after looking up half of those terms, yes, I think that's a good idea if the drain pipe is intact. For this many rocks, I'm thinking the pipe must have split wide open.
