Can I shave a hump in a concrete floor slab? Post your questions and get answers regarding all areas of drives, pathways and patios

Hello,

I've just laid a floor slab but have found that there is a large hump in one area that is about 20mm above the level that it should be. As I am laying insulation and screed over the top and the screed will have to match the level in an adjacent room, I need to remove the hump to ensure that I have a sufficient thickness to the screed.

Is there a mechanical way of removing this hump? (The concrete is only a couple of days old).

D-Mac,
Hard way - club hammer and bolster
Easy way - floor grinder - it'll cost you.
end

Thanks. I found the floor grinder on the HSS Hire website. You're not kidding about the cost - £70ish! But it has to be done. I can't think of any other way of sorting out this problem (I'm not going down the bolster route).
