Hi all,
Hoping someone can give some advice please.
I built a retaining wall a few years ago. Its 6m long and 600mm high. Made of 9" hollow blocks filled with concrete and rebar through to foundations. Usual drainage behind it and it's holding up well.
Thing is, the mrs now wants to make the lower ground level, even lower. Don't ask why. I'm not even sure I know why, but I've agreed to do the work.
So, I'm thinking of excavating in front of the wall and building a new, taller/deeper wall in front of it. Very crude picture attached. I will tie the walls together and fill the cavity with concrete. The front wall will be made of 6" blocks.
Any obvious reasons why this is not a good idea, structurally? I was particularly thinking of the drainage (where I have marked the red star on the pic). Will water find it's way here and cause any long term issues.
Thanks in advance
