Hi guys, I have a patio foundation that is in need of some serious help, has been for quite some years now. The front wall has crumbled in places to where I can see what I assume to be rebar and others are just gaping holes. I'd like to repair this wall and make it safe and not such an eyesore. The problem is I'm not sure if it can be "patched up" or if a more serious/extensive repair is needed. If anyone is experienced or knowledgeable with something like this and could offer some advice I'd greatly appreciate any input. Thanks so much!!
