replacing kitchen floor???

[geez01]

i'm planning on replacing my kitchen floor, its 4" concrete and badly cracked and uneven on investigating i've found there is no hardcore under the excisting just earth.I'm planning on digging out the existing and replacing the area is 16m2 my plan is to lay and compact hardcore base then builders sand to allow for dpm then lay a 4"base, does this sound about right? i would be grateful of any hints or tips also what concrete mix do i need i was thinking 5:1 thanks.geez.

Ideal opportunity to add 100mm insulation.
So, 150mm hardcore, 50mm sand, dpm, 100mm insulation, 100mm concrete.
Don't forget the mesh in the concrete.

1:5 cement :ballast.

2 men with a mixer, 1.6 m³ = one days work.

Think about how you're going to finish, trowel the concrete or 40mm screed on top.
The finish floor will dictate your choice to a degree.

you do not need fabric in there.. and 40mm is not enough for a screed... but hey ho... what do i know....

OK, I could say 50mm minimum, to be safe.

Who mentioned fabric?
I was talking about reinforcing mesh.

That's what geraint was referring to RedHerring - "fabric" is a trade term for it, rebar - same as. It's a bit OTT to be specified for a domestic kitchen floor.

OK point taken.
