Old solid floor leveling

[kowal]

Hi All

I am renovating one of the rooms in 80 years old house.
Most of the floors so far were suspended, this room threw bit of a curve ball.

It seem like a solid floor.
Top layer consists of tiles (2cm thick) under tiles there is some sandy cement pour which comes off with the tiles roughly (2-3cm deep).
Under that there seem to be some concrete.

Is there a way I could level the floor without extreme excavating?

Could I pour self leveling deep base over original concrete to level ~3 / 4 cm

Will you bridge the damp course at the edges?
Yes go for the self leveling screed.
Prepare the surface well so it sticks

I did not consider it but I will look into it now.
I am planing to cover the surface with acrylic primer.
Probably it is also worth to mention that the floor is actually above the ground level.

In most houses the damp course in the wall is level with the concrete internal floor. Take the skirting off as and you can see it. A black felt that runs along brick joint.

If you pour leveler it can bridge below to above damp course felt and cause problems. Just something to think about.
You can find ways to get around this
