Re: Perimeter Path height below dampcourse 6Oct 02, 2017 8:54 am Just a reminder that if the path will have an Overflow Relief Gully (ORG), there are clearances that must also be observed. The spill level (the surrounding surface) must be a minimum of 150mm lower than the lowest fixture connected to the drain, this will be either a floor waste or the shower drain. The lowest fixture will be level with the bottom of your weep holes. The regulations also state that where the 150mm minimum height cannot be achieved, a reflux valve must be installed in addition to the ORG. Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ Another thing to note is that the BCA also allows an impermeable path slope of 25mm over the first metre in a low rainfall intensity area. The rainfall intensity is based on an average intensity over a 5 minute period. As an example, an area with a 1:20 ARI of 120mm/hr (2mm/min) would need to record 10mm over a 5 minute rain intensity duration to register a 1:20 storm event. NCC 2016 Building Code of Australia - Volume Two Page 112 3.1.2.3 Surface water drainage Surface water must be diverted away from Class 1 buildings as follows: (a) Slab-on-ground — finished ground level adjacent to buildings: the external finished surface surrounding the slab must be drained to move surface water away from the building and graded to give a slope of not less than (see Figure 3.1.2.2)— (i) 25 mm over the first 1 m from the building in low rainfall intensity areas for surfaces that are reasonably impermeable (such as concrete or clay paving); or (ii) 50 mm over the first 1 m from the building in any other case.
