    hi,

    I want to build underneath a highset property in QLD.
    It has a concrete slab which is not level it has bumps and it's not smooth.
    The area is about 60 sqm.

    Carpet installers said the floor is too rough and it will feel like installing carpet on the sidewalk and the carpet will look really bad after 1 year (they won't provide warranty).
    Tilers said it has many bumps that will cause some tiles to come off after a few months.

    They recommended do grinding to smooth the floor.

    Is there any other flooring option I'm missing that could be installed in this type of floor as it is? Or any cost effective way to make it smoother?

    Thanks

    You could use a self levelling compound poured over the floor to make it level. This is probably easier than grinding it back

    Maybe just hire a rotating laser level and see where the low point sits,and i have used self-level mixes most times without form-work ..Grinding dust wise will not sort out the problem once those self level mix sets, very little work is required ..

    Useless Millenial tiler. Haven't they heard of laying a sand/cement screed or bed. Sad others have suggested a self-levelling screed will also do the job.

    Its quite common in commercial flooring for rectification work to be done before flooring can be laid/installed,most cities have specialist companies that just deal in floor grinding,self levelling and rectification of concrete areas, but mainly in commercial and large residential new builds.
    Just google it for your local area

    Any concretor worth their salt knows how to use levelling compound.

    Thanks all for your help. Your comments pointed me to the right direction.

    I got a quote today from a concreter that suggested to use levelling compound. He quoted me $2,000 to leave the whole floor smooth (it's about 50 sqm in total).
    Is that price OK for the work involved?

    thanks!
