Concrete garage floor has pot holes

[LaserTam]

1950s garage floor, has a few areas where the concrete has crumbled, leaving some pot holes. What would be the best method to repair these? Garage is fairly full of stuff so any repair will need to be just that and not a completely relaid floor.

Epoxy repair mortar? There's a whole world of epoxy concrete repair products for exactly this sort of job.

I would suspect the concrete is a bit 'not very good' and will want replacing before too long, so I'd be reluctant to spend proper money on patching it up.

I'd consider using an exterior sealer/primer then making good with mortar.

Probably the 'wrong' method, but it would be pretty easy to slosh some renovation screed (levelling compound with some strength) into the holes, assuming they're not too deep. Different compounds will do different depths, so check first.

I suspect it's been as it is for many many years, based purely on the apparent lack of up-keep in the rest of property, and the previous elderly owner wouldn't have used the garage much. But thanks for the advice.

Had a similar issue many years ago with bare concrete floor.

Gave it a good brushing, filled holes with ready mix screed and used proper garage floor paint to seal it.

Never had the problem again!

Concrete repair mortar is what you need, either in fluid or trowel-applied form.

Remove all the loose/crumbling areas, dampen the surface with water so it soaks into the existing concrete (no standing water), then simply pour in a product like this https://lilleytileandstone.co.uk/mapei-mapegrout-s... . Allow to cure then job done.
