Uneven floor

[steve1]

Planning to lay wooden flooring in the lounge, ( already posted about this ), have just removed old carpet, now I knew floor was bit uneven, ( old house and wall been removed between two rooms ), but after measuring with a site level it would seem that it's worse than I thought.
From highest to lowest point it's 37mm, generally it humps along the middle of the room, where the wall was removed.
Is my best bet to dig up offending area ( high spot ),and get it somewhere near, then self-level the entire area.
Don't want to just raise the rest of the floor to the high spot, as this would give me a bit of a step going into the room.
Open to suggestions.

If it was me I would work out how much (if any) you can remove of the hump. I suspect this will be quite dificult though. Then use a self leveling compound and fill the rest. You may end up with a small step but theis could be easily hidden with a wooden door threshold.

Thanx,
Link relates to wooden floors, so no good for me.
Think I will just get it somewhere near and self-level.

How about hiring a Floor Grinder. to grind away the high-spots.

Been thinking about these floor grinders, might be the best way, the less concrete/water I put in the floor the better, ( will need to let it dry thoroughly before laying the floor), has anybody used them, are they very dusty, or do the vacuum att. work well.
Seeing as I need to take off between 30-40mm to get it somewhere near, will I need an industrial size one or will a normal one be up to the task.
Thanx.
