I bought this house a few years ago, built in 1926. Not long ago, what was a slight crack in the porch became much bigger when the concrete gave way. Now I have a serious safety situation and haven't let people on the porch since. This slab sits on block foundation in the front of the house. I have had a couple of 'contractors' give me some ideas on how to remedy the situation:
- Cut around the perimeter, knock the existing concrete into the center, fill with gravel and pour a new top.
- Fill will gravel and patch existing damage.
- Jack up some beams from underneath to brace the existing slab and then patch.
- Cut the perimeter, bust out the existing concrete, Dig some footers and put a decking material on top.
I am really not sure of the pros/cons of any of these, but I am looking for a cost effective solution. I need to sell this house soon (family is expanding) and definitely don't want to be turning buyers away before they even step in the door.
