I am planning on finishing off my basement. However, the concrete floor is cracking and crumbling.?
Do I need to break it all up and haul it out? Or can I cover it with another product? There is limited headspace so if I can just cover it up, it would have to be with a product that wouldn’t add anymore than 2 inches. Any ideas? The concrete was poured in the 50’s or early 60’s. Thank-you!

Clean the exsisting concrete of loose debris. You can then skim coat the floor with sand mix or there are products made to overcoat bad surfaces that only reqiure 1/4" to 1/2" thick overlay. Check at your local home improvement store. There are also bonding polymers available to increase bond strength.
the real bad ares i would get rid of the crumbling debris and patch with cement patch then throw an indoortype outdoor carpet cheap quick and nice ps if you live in newjersey im tom 732 489 6889 contractor very reasonable
There must be a reason for the concrete? breaking up, its no good as it is, take it up and investigate, could be it is either too weak or, too thin
Are you sure you want to finish this basement? You are probably going to lose from 1 to 8 inches with a ceiling installed, not to mention some space for tile/carpet/hardwood flooring.
There are square tounge and groove osb sheets made to cover concrete. It is only an inch thick. It should work okay for carpet, tile, laminate or whatever. I would only finish the floor if its a dry basement though.
