Floor Leveling

[garyclay]

I intend to lay a hardwood floor in my living room, conservatory and dining room. The conservatory floor is currently 35mm lower than the other two rooms. All floors are concrete.

Rather than have a step between the rooms I'd like to raise the conservatory floor height.

What is the most cost effective method of doing this?

Thanks in advance for any advice.

You need floor leveling compound,see this.

They are some which will go up to 40mm,can't remember the name.

How about a floating floor ?

Hi,

How would a floating floor even out the floor levels?

 

[Scoby_Beasley]

It would if you don't make waves !!!
Basically its slabs of polystyrene covered with interlocking c/board floor panels, just thinking it might make up your height difference.

Ah yeah, I've seen these. Good idea. But as you say only suitable for a floating floor. I'll need to cover the entire floor with 1/4 inch ply before laying the floor anyway in order to be able to nail it down. Doubt I could lay it over the insulation without it being rigidly secured.

Thanks for the idea though.

I would buy roofing battens (19X38) and plane them by 2mm to get a 17 X 38 timber screwed and plugged to the concrete floor at 450mm centres , and then lay 18mm T & G Chipboard flooring on top which together with the new depth of the roof batten (17mm) will give you 35mm.
A different method would be to achieve the full height needed and eliminate the need to add ply to the conservatory area by fixing lengths of 22mm floorboard , screwed and plugged to the concrete at 450mm centres and then lay 18mm T & G chipboard flooring on top which will give you 40mm so when you add the 1/4 inch ply to your existing floor it will be almost spot on.
