So we have a retaining wall (Made of landscape cinderblocks) around our backyard patio (our concrete patio is about 3.5 feet above our grass). the retaining wall is about 3.5 feet outside the patio at the widest part, mostly it’s about 18 inches to 2 feet. So whoever built our retaining wall around our patio did not alternate corner blocks at the corner to tie the two walls together 😡 . So now we have one side of our wall separating from the other at the corner- there is like a 1/2 inch gap and I think it’s getting wider as one side is pulling away. The blocks have concrete in every hole and rebar hammered down every other from what we can see when we pull off the caps.

big question- is there a way to sure up this wall without dismantling it all? How can we do that?
