    does anyone have any suggestions on what to replace a concrete floor with in an old stone wall cottage?
    the present one has cracked and i think in past it has contributed to rising damp (it has coal ash in it i believe, used as an early dpm).
    note that in the other room we have a very thin 2-3" screed of what appears just to be concrete on hard earth, and this does not appear to have suffered from rising damp (we were originally told so by an expert who had somat to sell, but i think it was condensation spots).

    my builder has suggested that any replacement needs a dpm, but i think that would just start any rising damp issue again.

    also, we are wary of digging too deep due to foundation issues (or lack of).

    Yea limecrete. If you put a dpm in the floor you will force the damp up the walls etc etc...

    how deep do you have to go with it?
    also, is it the case the moisture just comes up in a controlled manner with limecrete. if so, do carpets and underlay suffer from the "damp"?

    100 or 150mm and use breathable carpets.

    how does a limecrete floor allow the upward movement of water from the ground when it's built over foamed glass / leca which, as I understand, don't absorb water?

    water vapour will still move through leac and the gaps between the foam glass

    the funny thing is that it will tend to move away from the building as it moves towards the cooler places!

    You may well ask why do we need damp membranes then :neutral:
