Just wondering how viable it is to take up a screed floor then fix battens so I can fit floorboards. The timber floor in my living room needs redoing. I don't fancy a floating floor on top of the existing. There is however an extention which is concrete. I have been told in theory I should be able to break up the screed and screw battens to the slab being careful not to penetrate the dpc but how thick is the screed and the slab usually.
