What kind of floor? PVC, Timber, Stone, Carpet?

Hi!

I need some advice about the top of the floor. But I have a little problem. Doors and walls are made, and the space between the door sheet and the floor is 30 mm. And the concrete is not regular, it has some irregularities, and we must smooth down it.

So this smooth works need at least 20mm. My question is:

What can I do with the floor? PVC floor? Floor tile over this irregular concrete floor directly?

thanks!

Is this concrete floor part of your new construction, or is it the floor that existed in the building before you started your construction?

Is the actual floor uneven by 20mm from lowest point to highest point?

Is the existing concrete solid, or is there flaking, cracking, loose parts, etc? Steve

is a floating floor over the existing floor. 40mm rockwool 150kg/m3 and 60 mm concrete with metal mesh.

"Is the actual floor uneven by 20mm from lowest point to highest point?"

Yes. I think is no more than 20 mm.

"Is the existing concrete solid, or is there flaking, cracking, loose parts, etc?"

It's solid.[/b]

OK, so you're telling me that you poured a 60mm slab over rockwool and that slab is the one with 20mm irregularities? How is this possible? Did someone just dump concrete on the rockwool and let it dry?

Hi,

i used Isoself grains to fill up the floor (app. 40 mm, from 10 to 40 mm) and covered it with osb-floor panels. The whole floor is 60 mm high, (40 mm isolation grains + 22 mm osb). The osb is screwed to the wood frames in the floor. We used a self ajusting horizontal laser to check the hights.

perhaps 20 mm is so excessive

. But I lay down a piece of carpet and walk over it and feel irreguralities in my shoes. And when we install the door we have problems with levels because of it.

Maybe there are some shapes in some parts of the concrete.

You mean my room?

It's an attic...

The room will be used for mixing only, acoustic treatment will be done after finishing the rest of the house (renovated the full house, heating, electric etc.) after we move in.

I will start a thread about the the treament (listen, measurements etc. ) then.

@Hugo: there is something we call "Fließestrich" which means self leveling concerete. It is a thin fluid concrete you can use to just pour into the room and it will find its way (almost) alone and get an even floor.
