Have a large rear extension which will be knocked through into existing rear rooms of house. New floor will be concrete, membrane insulation and screed. Existing is 1940's suspended timber floors. Although an older house it is cavity construction, brick outer and brick inner with a slate dpc. I'd like to remove the suspended timber floor and make a continuous concrete floor which lends itself well to underfloor heating for the whole room. It won't be possible to lap the membrane in the old part of the house into the brickwork with dpc. any other ways around this to ensure no moisture rises up walls from below membrane. Thanks in advance.
