    Has anyone ever added screed to a hollowcore floor on upper floor of house that they are currently living in, is it a messy job?
    I have solidwood floors attached directly to battens above the hollowcore at the moment but they squeak so much so I am considering screeding the floor underneath if anyone has done this before and it didn't cause too much a mess.

    2 to 3 inches of concrete weighs 180kg for every square metre of floor. That is a lot of extra weight. You need to make sure your hollowcore is designed to carry that extra weight.

    That means going back to the original hollowcore supplier and asking them to re run their design calculations with the additional weight.

    It's quite rare not to screed hollowcore in order to tie the slabs together. I think I've only seen it once ever. Where did that detail come from?

    I know of lots of houses done this way. Possibly silly short cuts I don't have any building knowledge. But guess from the level of sound travelling through should have been done.
