Uneven floor

markc1184

I recently had a major water leak in my house. We are about to start having new floors layed. After lifting the old laminate floor in the living room, underneath was a concrete floor with what looks tiles on top of it. These tiles are about 4mm thick. These tiles are also in the hallway. There are some high and low points in both floors . More low than high. There are also some cracks and gaps along with a couple of tiles missing completely. What would be the best way to go about levelling this? Is it a case of using the likes of a polyfilla? Or would a levelling compound be better? Is it even a job I should be considering taking on myself or just have someone come in and be done with it?

I'm unsure if this makes any difference but it will be a carpet replacing the laminate which has been lifted in the living room and a vinyl/Lino in the hall.

EDIT. I have attached a photo of the tiles.

It might be a good idea to identify these tiles. They were very popular in the 60s an 70s and pretty much all new homes were floored with them. I remember them being called thermoplastic tiles. There is a possibility they may be vinyl-asbestos tiles, which are fine if they are not disturbed but could be an asbestos risk if you start digging them up or abrading them in any way. Whether thermoplastic and vinyl asbestos are the same thing I don't know.

We just got floor levelled today..it had some parquet underneath and some low parts where old porch was and door saddle..he used self levelling compound as we are putting Karndean down. Amazing job..and quick for him to do. He had to put damp prof membrane in old porch area to as there was excess moisture
