So my front porch(6' long and about 14' wide) has crack right in the middle going from the house to the other end of the porch (6' in length). My front door is about 2' off the ground and the porch slab is supported by red brick on the sides and front and ties into the house on the backside of the slab. The crack has worsened with time and now one side of the slab is about 2" higher than the other where it meets the house. No doubt that water is getting in. For all I know, its hollow underneath - seems sturdy when I stand on it, but I'll assume there's no gravel, no sand underneath.
My question: Is this something that can be leveled the way that a driveway/sidewalk can be leveled - with foam or some other substance? Or, do I need to get the whole thing ripped out and repoured? Thanks in advance.
