    Default Suggestions for balcony floor not tiles or timber

    Hi. We are building a house with a large balcony. The original plan was to have it tiled, but I’m rethinking that due to cost, labour, waterproofness (lack of) and weight. Of these issues, waterproofing is by far my main concern.

    So I’m searching for alternatives - some sort continuous skin coating perhaps?? Maybe something more often used in multi-storey appartment blocks?


    Balcony details:

    Elevated, 4 metres or so above ground
    54 sq meters
    Construction is structural steel posts and beams, supporting LVLs on 450mm centres.
    Subfloor is dense fibrecement about 16mm thick but not sure of brand.
    There is a roof over, but it still gets some rain when it’s windy.
    Currently professionally waterproofed.
    Will need a concrete screed to get the fall (unless there is some other alternative).
    I expect there will be another layer of waterproofing on top of the screed.
    There is a room underneath part of this deck, plus another deck underneath with an expensive cedar ceiling - thus sound waterproofing is essential.
    Bushfire rating is low but nonetheless we can’t use any timber based solution.

    So any ideas please ?

    polished or painted concrete
    dekton (or one of the other man made stones but that will be $$$$$$$$)
    fake wood decking (no maintenance)

    i would have thought tiles would be the most used thing in multistory buildings

    Once worked in a building which had a rooftop area for social gatherings, fenced off from the plant (AC etc)

    Needed waterproofing maintenance so they used a 'skin' of some sort.

    The first after-work drinks and stiletto heels quickly saw the end to it being waterproof!!

    They skinned it again and closed it to social gatherings

    Polished concrete would be great - but would it qualify as waterproof?

    I wonder if the screed and the polished concrete could be combined somehow - or would the polished concrete have to sit on top? If so it would be sitting on a layer of waterproofing - so are there adherence issues.

    Anyway it has my vote on aesthetics alone so maybe time for some research.

    Anyone had any dealings with polished concrete in a similar situation.

    Why can't the balcony be built with a fall?

    Edit: oh, re-reading, it appears to have been built... 20/20 hindsight

    Yep, already built, but the question still applies.

    But your deck isn't concrete and the structure may not be designed for it!

    Indeed. All part of the investigation process. The engineer will advise.

    Yep, it really is crap.

    Imagine, "We built a flat roof. Please arrange someone else to create a fall"
