Gday all. Does anyone have the codes or how I can find the code to distance below weep holes for concrete path around the home. I have read through random threads it’s 75mm but I can’t find the actual document.
Spoke with the concreter and was told it is 75mm but can go to 50mm below. I’ve also read 50mm is if it’s covered by a veranda or structure. We have eaves so does this include covered?
Just chasing the correct document but cannot find the info required. Our concreter wants to go 50mm below but left the choice with me to decide 50 or 75mm.
I think it will be an issue at the rear of the property if we go 50mm because the outdoor entertainment area will be lower that concrete he pours. We do have a drain but don’t want water pooling in there as it doesn’t always drain away straight away.
I prefer what is required by legislation if there is such a thing in Victoria.
The damp proof course sits at the bottom of the weep hole.
The location of a damp-proof course or flashing serving as a damp-proof course, must be not less than—
(i) 150 mm above the adjacent ground level; or
(ii) 75 mm above the finished surface level of adjacent paved, concreted or landscaped areas that slope away from
the wall; or
(iii) 50 mm above finished paved, concreted or landscaped areas complying with 3.1.3.3(b)(ii) and protected from
the direct effects of the weather by a carport, verandah or the like; or
(iv)
in low rainfall intensity areas—(A) 15 mm above finished paved, concreted or landscaped areas; or
(B) 0 mm above finished paved, concreted or landscaped areas if the damp-proof course is protected from
the direct effects of the weather by a carport, verandah or the like
I've always known it to be:
The height of the DPC or weep holes must not be less than 150 mm in areas where there is adjacent land (Soil etc...) to protect for ground movement. It can be reduced to 75 mm in areas where there is concrete/pavement that slope away from the wall. It can also be reduced further when protected by a carport etc.
I've known of people not getting their occupation certificate due to inadequate clearance to weep holes, so make sure you get it right. It's one of the most common defects I see when conducting insurance surveys. Concrete paths in most cases are too high.

You are correct. Just read through all the ncc rules and 75mm is the minimum requirement for me.
