Hello!

I have bought tiles for my hallway which is 4.2 km.

I live in a concrete house from the late 60s. So my ingenious idea was to tear up the masonite floor and lay the tiles directly on the concrete floor.

Said and done, I have now torn up the masonite floor and under it, there is 6 cm of gravel/sand as some sort of leveling/soundproofing.

My thought now is how to proceed, what would you have done?

The options I can think of are:

Remove all the gravel and fill with concrete/self-leveling compound to the correct level and then lay the tiles on top.
This method will cost me 1500 SEK or more.

Option 2 is to frame the floor and put plywood/floor gypsum boards? Then tiles on this? Does it work?

Option 3 is simply replacing the masonite with plywood/floor gypsum boards without framing and then laying the tiles directly on this? Would that work?

Or is there another simple way?

I've been to K-rauta, Hornbach, and Bauhaus and talked to them, but everyone is just as puzzled when I say there's gravel under the floor and claim it must be some sort of shoddy construction. But I've googled and seen that this was common in the 60s.

Grateful for any possible answers!

Replace the gravel with EPS, then apply leveling compound and possibly install underfloor heating within it. Don't incorporate any wood into the mix.

Thank you for the quick response!

Is EPS the styrofoam block? Should you just lay them on the floor and then put filler over it?

No, EPS is a kind of concrete mixed with polystyrene beads.
 
No "Polish construction method" but common in multi-family houses in the 60s, just incompetence from those you met at the hardware stores. Because you live in a multi-family house, right? If that's the case, check with the property owner/housing association, always a good idea. And of course, you pour/level up to the correct level, i.e., the height of the old floor minus tile/adhesive.
 
Also a very common method in houses.
