I have pulled up an old carpet ready for a solid wood floor to go down and in the concrete slab under the carpet there is an area where it has cracked.

The crack is not large (1-2mm wide at most) and so I am wondering whether I need to fill it before fitting the new floor or whether I can just leave it. Obviously it won't be visible and it won't be exposed to water etc so from a purely functional point of view I am wondering whether leaving them will create any issues.

Thanks in advance!

ETA: The wooden floor going down is solid but floating and so nothing will be glued to the slab

Clean the crack out the best you can and fill with an epoxy filler, something like https://www.promain.co.uk/centrecoat-crack-filler....

Best to post pics but sounds like it would be fine to leave

If you want to fill it then something like would do : https://floormart.co.uk/f-ball-stopgap-400-rapid-r...
