    New build house that floor had a join where it was laid in 2 parts as a wide room.
    Had flooring company to supply and lay Amtico, never mentioned the floor could be an issue.
    6 months later a line has appeared through the tiles, fitter came back the screed had cracked so they filled with a resin and replaced tiles line has come back again and they are now saying the floor must be moving? and cant keep repairing
    Builders adamant that there is no movement. they are saying the join was visible and if they thought this may be an issue in the future it should have been brought up before they laid Amtico.
    Also finding more lines and also bumps.
    Bathroom has a line, it was laid over chipboard, they said they didn't need to use plywood because of screed that they use,
    Any Advice please.
    Will we have to go down route of independant assessor?

    Any pics?

    Firstly the bathroom ideally should have been plyboarder with atleast a 6mm ply but you mention they used a screed over the chipboard? - would you be able to fund out exactly which screed they used??

    As for the line that keeps reappearing then even with the slightest movement it's going.to create a line but if it was prepared correctly then it could have been avoided. It's alright dripping epoxy down the crack/gap but if it's not the right material then it will crack again.

    This all depends on 'how bad' it was in the first place where a stitch system wouldnt help either. It could have been that the floor should never have been laid over a crack that is 'past' bad.

    All new builds dont settle for a couple year anyway but in my experience if the crack is to big then I wont entertain it. I have used a stitching system by ardex a few times but not on new builds/new floors

    Chipboard should always be ply lined
    The screed has probably cracked over the board joins

    The two separate slabs should have had a crack bridge or crack repair system used before the smoothing compound was put down Its just lack of knowledge from the flooring contractors

    Screed is f balll 1200?
    I don't know how to put a picture on it keeps saying file is too big?
    The builder did mention to the flooring guy that on other properties that have had these joins a different flooring compay fitting ceramic tiles had requested crack mats over them which the builders did. So if they had requested something was done beforehand they would have done this, not now when the floor has failed.
    The flooring company said the screed they use F ball 1200 can be laid over anything as it is flexible.

    If any subfloor has any movement all smoothing compounds will crack unless steps are taken to deal with the issues

    As I said lack of knowledge

    If we go with getting an independant flooring accessor, who should we be looking ( NICF?)

    Unfortunately I am a bit behind on subfloor prep. Nothing as brittle as a tile, a levelling compound or as thin as lvt should be bonded to a new screed. We should be using some type of decoupling matt like the tiles do. No guarantee on going direct to any subfloor chipboard or screed

    Without seeing the join between the slabs it’s hard to tell. It should of been floated over, decoupling matt used or a expansion shadowed through the floor covering (which no customer will accept)
