We just bought a house with a nice sized patio. The only thing is that the backyard is on a very small sloping hill. Because of this, much of the ground has eroded, causing the bottom of the slab to show and patio to be pulled away from the foundation of the house (about 3/4"). Our predicament is trying to decide what we want to do with the space. We have gotten quotes for building a deck on top of this slab, but they are pretty costly. I was wondering if it is possible to somehow salvage what is here by possibly filling in the gap, maybe putting footers at the end of the slab to keep it from moving anymore? I am honestly completely in the dark to this as I have no experience with this or how to go about it. Is it better to just go with a deck that will have big support posts put in the ground, or is it possible to maybe salvage this and put a retaining wall at the end or something like that? For the grass (or lack of) we are going to try and install artificial turf as our neighbors have tried everything for their grass and cant get any to grow. Any help would be greatly appreciated!
