    Planning to dig up concrete floors to insulate in my house retrofit. It seems that the general guidance is then to relay more concrete on top. Floors in this situation are not really load bearing surely so why the need for concrete? We drive cars onto block paving laid onto compacted sand and hardcore, trains seem to run on sleepers laid onto gravel! Anyone tried using clay floors?

    What sort of parties do you have? A car weighs about as much as 25 people? Call it 10-15 people plus furniture, sofas ? What's do you want to put on top? Tiles need a reasonably solid base hence the conc.

    If you're guaranteed bone dry, and a bit of uneven floor is all part of the fun, then hefty pavers laid on a good bed - why not. However - on top of insulation? They'll never bed down solidly, always a little bit of 'spring' to upset things.

    Tried making 12" sq x 2" thick pavers of cob? - with lovely encaustic patterns by 'swiss rolling' different colour clays. Bed and point in clay mud. Finish with lots of linseed oil - it'll soak it up to give a moppable surface.

    The basic principle is that the whole floor needs to be inflexible and non compress able i.e. Rigid otherwise you will get some compression under the main tracks where you walk, the substrate will compact a minis clue amount every time you walk over it even with paviours this can happen, look around your area at the driveways.

    A mud flor is great but not flat and lower in the middle than the edges.you can always add more but will you want to be re levelling your floor?
