    Hi everyone.....
    Been doing flooring a while and come across a job I’ve been asked to do but in my opinion it’s going to need a lot to do it right so just seeing what your opinions are fellas..... here goes
    Karndean floor install
    12 metres into timber and 10 metres onto concrete.
    Where the floor meets they had carpet down over a bad screeding job with old vinyl tiles around perimeter.
    Where the floors meet there is a section of blown chased out concrete and pipes exposed and it’s only about 10mm thick and then the remaining slab is cracked in places and hollow.
    I’ve told the client the only way to proceed is to either install a new floating timber subfloor over the lot with a dpm and insulation or the loose concrete be removed the pipes be laid 100mm down and loose slab chipped out and filled with ardex a35 mix.
    The remaining sub flor to be grinded back to sound concrete and then sandwich dpm over it all which is one hell of a cost.
    I’ve said there was a carpet down for a reason and it was hiding the hellish mess underneath.
    So basically I’ve said to just to Karndean in the timber area and replace carpet like for like.......
    Anyone think this was a good way to go
    Many thanks
    Sam

    Well that’s kind of what I’ve done..... I’ve told them what I think it needs as at the end of the day they will want me to guarantee my work and I can’t unless there is a bell of lot of additional work done first which will cost probably as much as the new kitchen :):)
    Just wasn’t sure if I was being too safe but then again manufacturer’s recommended installing methods are there for a reason I suppose

    I would get it flat then put a cement board over it then float or bond a laminate or engineered
