conservatory floor

[sewin]

Hi could someone please give me instructions on how to lay a concrete floor in a conservatory...what mix I need to use for the concrete ....how thick....etc thanks

2-3 inches hardcore,bind that off with sand,lay oversite membrane down,
then lay 50mm polystyrene for insulation,then 100mm min concrete,
make the conc wet,but malable,level all the way around the inner walls,
then fill in the middle,easy
