Limecrete Flooring with UFH in a basement - damp issues

I'm buying a semi basement flat (early victorian/georgian).

One of the walls in the flat is a retaining wall, the other walls are above ground but don't have a DPC.

I think the flooring is laminate laid on top of a concrete slab.

I am almost positive the survey will come back with damp in the masonry walls and floor slab.

I'm buying the flat cheap enough to do damp proofing work and install a new floor through out.

I am thinking of installing limecrete floor with underfloor heating and exposed stone floor, so the slab and the floor can 'breath' moisture into well ventilated rooms, and reduce any rising damp in the masonry walls.

Then install a cavity wall and drain along the one retaining wall, to drain excess water away into a sump pump.

Does anyone have any views on this plan of action?

Has anyone installed a lime crete floor with ufh and breathable stone finish?

Any thoughts much appreciated. :)

You will need insulation in the floor otherwise your underfloor heating will be trying the heat the earth's core.

You would normally be expected to install dpc under the insulation, which will negate the requirements of having a limecrete floor
