How do you fix a cracked concrete porch?
nodito

We live in a 1907 bungalow made of concrete block that has a large, deep concrete front porch. The porch floor is uneven, stained, and cracking. Parts of it are shiny, so I assume that the previous owners tried to seal it somehow, and I'm told that merely adding more concrete on top won't hold. Short of tearing out the porch and starting over, what are my options? Can I put wood flooring over it? Some sort of stone? Something else? Whatever we do I'd like it to look good with historic concrete block and also be appropriate for a home built around that time. We live in Massachusetts, if that matters. Thank you!

Talk to local foundation experts about jacking the foundation back to proper height.

"Short of tearing out the porch and starting over, what are my options? "

Not many options there - fill in the cracks with concrete filler or elastomeric caulking, top with portland cement/water mix, top with quikrete topper - none of which will give you the "look" you wish, unless you finish it with something like garage floor finish.

"Can I put wood flooring over it? Some sort of stone? Something else?"

Wood flooring won't do well in wet conditions, unless the porch is completely enclosed and water tight, which is very unlikely.

Stone? might only work if the cracks are not quick to appear or to form. Every type of flooring is only as good as the sub flooring.

Your best solution will probably be a total re-do, or a demo and installation of a different porch floor system.

Minor cracking can be patched but major cracking indicates the slab's support has failed or was inadequate from the start so even if you can re-level it the cracks will remain and need patching. And anything you put on top of it will simply adds weight and settle with it. Concrete is a great building material and quite strong but it has it's limitations and one of those is it's lack of easy repairability when major problems occur.
