    Default Possible waterproofing mistake

    Im looking at a job of waterproofing done by a professional waterproofer.

    Its a balcony, with a screed, waterproofed above and below.

    What looks odd is that in several places the screed butts up to the house cladding, which is rendered polystyrene (Orangeboard). Here the waterproofer has done a liquid membrane across the screed and about 10mm up the cladding. There appears to be no bond breaker. That looks wrong to me as Id expect a bit of movement between screed and cladding.

    Any advice.

    Cheers

    Are you sure he hasn't siliconed along the join?

    No, I’m not sure.
    Is that a legal and recommended way to do the job?
    I thought some type of ‘bandage’ was mandatory?

    I’m also presuming I would see the imprint of that bandage through the membrane. Maybe that isn’t so?
