Concrete floor in two halves

Discussion in 'Builders' Talk' started by hopefulBuilder, Jun 29, 2008.

  1. Due to circumstances we need to have the concrete floor of a new kitchen extension laid in two separate halves. I am worried that when I later stick ceramic floor tiles down, there might be future problem with cracking at the joint of the two floor halves. (extension size 5m x 5m)

    Should I do anything at this stage to reduce problem? (eg. leave bits of rebar protruding when first half laid, to tie the two halves together)??

    do the 2 floores seperate is not a problem in any way and shouldnt be worried about, we have done a floore in 4 parts before , due to the size of the floore area. once ints down it doesn't move, unless you didn't have a solid base of hardcore underneath which building control doesnt allow anyway
  3. Thanks, that is good news.

    Except -- the person doing the floor has only put 40mm of hardcore instead of the 150mm shown on the plans. I will be "discussing" this with them. But I guess you are saying that it is important to have the thicker hardcore base?

    (obviously the concrete has not yet been laid <grin>)

    It certainly wont do any harm to stick a few bits of rebar in,just in case or even fix a couple of blocks on the first shutter to make a "tongue and groove
