Modify the BarB Que to sit on the wall, a mistake here would be costly.
When we build a retaining wall it will have a 10 or 12" footing and maybe 3 ft wide mostly under the high side.The wall has a 4.5" concrete footing (as can be seen in the picture). Otherwise, I don't know how it's constructed. I was wondering about digging underneath the "gap area" and somehow filling down with concrete. Any thoughts on that?
