Hello
I tore up the parquet floor to lay a new one and discovered holes, cracks, and settlements in the underlying joist structure, which is some type of concrete. In one settlement, I removed a piece and there was sand underneath. The settlement is the size of a footprint.
How do I repair/fill these? Type of mortar or house fix? Should I remove loose pieces? How do I get adhesion to the sand?
The house was built in 1956.
Regards

Buy a few bags of concrete and pour in.. scrape clean and vacuum the cracks of all loose material (so it doesn't crawl up under your new floor later). You can then fill in with a little house-fix. Preferably wet the surface with a thick brush beforehand for better adhesion.. Remember not to apply too thick a layer of filler, so you don't get a slight ridge/height there. Better a little too little than a little too much.. Difficulty level 3
The alternative is to slather it in and then level the entire floor. Difficulty level 8
The solution depends on how uneven the floor has become. If you level it, you should expect to lose at least about 20-25mm in ceiling height from the finished floor compared to before. Also possibly a raised threshold from the adjoining room...
