I have an old (1810) listed building which has some damp issues. In the kitchen where there is damp at the base of the internal walls there is a (added in the last 30 years) concrete slab. Buildings of this age have no DPC and as the concrete itself looks to be damp, my feeling is that the concrete slab meeting the solid brick walls are probably contributing to the problem. Reading on buildingconservation website: https://www.buildingconservation.com/articles/solid-ground-floors/solid-ground-floors.htm One of the suggestions is to use a limecrete perimeter around the slab. This provides the capillary break required, allowing the substrate to breathe and preventing the footings from drawing trapped moisture into the walls. "A hybrid floor design with a modern slab isolated from the walls by a vapour permeable limecrete perimeter strip" To me this sounds like a sensible and relatively un-invasive option. Just wondering people's thoughts on this? Has anyone ever heard of this being used with success/failure? Modern DPC injection is out of the question so this sounds like a decent thing to try.

I am in the throes of doing my insulation in the floor. Perimeter strips will be done around external walls. Is there any great benefit in doing this on the internal walls as well rather than just the foam strip? Thanks in advance.
