The concrete is just about level with the top of the joists and level with the other floors in the house. I've had another think about it and may just latex the surface to flatten it all off, lay a polythene dpm, new t&g floorboards and top it off with the laminate. The neighbours leak has been fixed so I can't see a problem with water pressure forcing any water through the latex although I realise that the damp will still rise through capillary action but I'm hoping that the dpm should hold that back. I'm not too worried about the joists at this time as the concrete seems to add support to the structure. Any thoughts on this course of action ? Franko.
