    No subfloor? 9th Nov 18 at 5:13 PM
    Really need advice.

    We have had a bit of a dispute with our builder who we have now got rid of but we have massive concerns over the new floor. At the time he said he would use all the rubble that lay from knocking down walls instead of concrete for the subfloor. He said between that and some blinding he would 'whack' it and that would make it as strong as concrete. Is this acceptable? At the time when we questioned it he said building control approved it but building control do not recall this! HELP! We are now in the house and screed and all is down 2 months, if there is an issue we will have to dig up all of it

    A worried home owner.

    Are you saying the builder used hardcore ( old building material ) for the floor rather than concrete? did they then put a layer of screed on top of it?
    ITS NOT EASY TO GET EVERYTHING WRONG ,I HAVE TO WORK HARD TO DO IT!

    It does not sound right. Is there any insulation in the floor?

    Yeah he used the rubble and blinding he said. Then insulation and screed. Although the screed has cracked in the walk in wardrobe and its evident that there's only about 1cm in that particular area

    He did, he used kingspan sheets. Our plans recommended 15cm but I think there's only about 10. Architect says that should be ok though, but now our concern is the subfloor.

    Screed can go on top of insulation(min 65mm), but there should be concrete under the insulation.

    For him to say building control were ok with this is a blatant lie then. And to make matters worse, he quoted for the flooring as to plans so he has been paid for something he didnt do. Although we are increasingly finding other things he has been paid for that haven't been done to spec. My last conversation with building control was that they had no record of the floor being ready to go down and builder was to provide photos to prove it was as guy couldn't come out to see it before screed was put down.

We should have known something was up when he constantly asked for money and there was little progress to show. We had complete trust, we knew him.

    Although the floor has not been constructed properly, it may survive if the hardcore has been well rammed and a DPM installed. What have Building Control suggested? It would be a fair bit of work to rip up the floor and redo it.

    We are waiting to hear re: building control. Architect and surveyor are saying whole floor will have to come up unless there is a specific reason building control would let it go. But if there is any doubt over the integrity etc who takes liability 10 years down the line? Then the financial aspect of it all, he was paid for what was specified. This isn't the only issue, but it's the main one we aren't prepared to let slide.

    I'm surprised he told you that he was going to leave the concrete slab out, as he must have known that it's an important part of the floor structure.
