Replacing Quarry Tile Floor With Screed / Concrete

[RealityTested]

I have a 1930's end of terrace house which I am currently renovating. The kitchen floor had broken quarry tiles laid on an sand and earth. I have currently dug this out to about 7"'s.

I am not looking for something super tough, just something that is stable and within a good budget / easy and quick to lay. The total area to cover is about 24m2 and I would like to be able to lay tiles on it as soon as possible

Can I put down for example

5cm hardcore
2cm blinding sand
5cm Jabalite insulation
DPM
and then a 5cm screed?


Some people I have spoke to have indicated this would be ok and it is certainly more solid than what was previously there.

Can any one advise me on whether this is acceptable / a recipe for disaster. Or alternatively tell me the proper way to do it..

Kind regards

just lay a 100mm trowelled concrete slab as opposed to screed.

it may mean digging a little bit more off or forsaking a little hard core or blinding, but 100mm slab, is a minimum.

Thanks for your reply noseall.

I wonder however if you or someone else could clarify

1) Why to use a concrete slab over screed (I assume it is to do with how strong it is?)

2) What the order / minimum depths are for each layer (ie Hardcore, sand, insulation, DPM and slab?)

3) What Kind of insulation you would recommend

4) Also if a quick drying concrete is used to make the slab would it be possible to lay tiles on it say 3 weeks later?
