Is it possible to remove some of the concrete base slab to make the ceilings higher?

Asked .Active .Viewed 190 times.

We would like to extend our extension and install underfloor heating there. Now we have a problem with the ceiling height. Currently it is 190 cm. Underfloor heating is 25 cm high. So the heating engineer said that we have to go 35 cm lower than we have now so that we have a reasonable ceiling height. The current base is a concrete base slab. Now the question is, how do we get the base slab back into balance if we chisel/remove 35 cm from that base slab? Or can anyone tell me about the construction of the floor all the way down to the underfloor heating?

  • Build the heater into the wall.
  • If you want to insulate, then use a dry screed with a thin layer of insulation, then ideally only 5 cm of height will be lost. And attach the panel heating to the wall or ceiling



There are also retrofit systems for underfloor heating systems, they only require a few cm of structural height.

  • We still have a ceiling beam in the middle of the room. The beam still protrudes into the room. If we ramp up now, I'm going to hit my head on the beam.
