how do you fix a concrete porch?
over the years with the cold weather and rain and just old porch. My corners on my back porch are crumbling. I have done a repair job on them once but after several years have taken its toll on those concrete blocks. and the remaining of those blocks are starting to crumble and crack again. can I just knock the remaining of those blocks out and replace them and use something to fill in the gaps? the porch was made with concrete blocks and a huge slab of concrete block for the top of it. can I replace those two blocks without screwing up the foundation of the house along without tearing the whole back porch up.

Reading your question gives me the impression you are out of your depth, you need a professional.
I worked for a company that specialized in repairing deteriorating concrete buildings. They would have us chip out all loose concrete, then form the shape back with wood forms smeared with vaseline. The final step was to inject a hot-mixed two part epoxy resin lightened with what they called "micro spheres" into the cavity and then we would wait half an hour before removing the wood forms. It's expensive, but extremely strong and will last forever.
If you can't tell whether or not you're going to screw up the foundation, I would hire someone who can. I've seen some catastrophes, and they're not pretty.
