I have a 1930s built house, where the foundations are a concrete raft and most of the ground floor is then a raised timber floor on top of that.
The utility room that I wish to tile is not on raised timber, it has concrete. It has changed shape from the original layout, so has a small strip of floor that was in the original garage. A previous owner has glued some rubber flooring before laying carpet; the rest of the floor has some 1950s vinyl tiles stuck down with impact adhesive.
I suspect this floor (based on another section that was taken out) is some hardcore followed by a layer of concrete (it's deep - ~250mm). Neither part shows any evidence of damp (the vinyl tiles are still stuck down adequately some 60 years later), but have no idea if there is any DPM. I can see some bitumen DPC on a bit of brick wall that was knocked down (and there is the same on brick piers holding up the timber floor elsewhere), so I suspect not - given the rubber that was laid on the old garage. I'm guessing it's been OK because the FFL is above the outdoor ground level, and 'rising damp' is a myth. Frankly even the top of the concrete raft is dry as a bone.
Anyhoo, I was intending to make good some of the holes where brick walls used to be, then apply a layer of SLC to make life easier for tiling. Sound sensible / good product recommendations ?
