Thanks for the video it was very well well done. I think the new 3740 is going to assist with things being sealed for good, i get that some may opt for no voluntary waste with the associated costs but those costs are no worries for the serious builders, the high end. I think the more serious wont have a issue with fall to waste wherever theres a chance for water to encroach for whatever reason and membrane to 1500 from the shower if its not fully enclosed and why not the whole floor, in any case get the water stops in, all that, and if your enclosed its fully enclosed as required and in any case if water is around after 5 hours in normal conditions its deemed pooling, even with a enclosed shower water can get out from containment but at least make it unlikely if you have that situation you can have a flat floor and no waste just be able to address the 5 hour rule and your right under normal conditions. I got lots from this, great video Gripset as usual.
Hi Andre! Really thanks for your contribution! Great points keep them coming! Have you registered for next months webinar? lnkd.in/gdD8FMMX Let us know what other topics you would like covered. Also stay tuned we still have a few more AS3740 update episodes on there way. Sincerely appreciate your support!
@@GripsetIndustriesPTYLtd Yes I have registered for sure, was really easy, totally easy. Cant wait for it 19th July 5pm. Quality Control and Industry Update, what you need to know. Thats really exciting. I just wish to be able to take detailed notes, part 1 was very impressive great content.
Hi. Thanks for the video. On my reading the standard requires the fall to be on the substrate? Or the video suggests the fall is not needed on the substrate, and you can create the fall on the screed and waterproof over? Thanks
Hi Mike, refer to sections 2.3.1 and 4.2 of AS 3740 and extent of waterproofing requirements under the NCC volume 1 - Part F2, and NCC Volume 2 Part H4. All components relating to placement of membrane relative to falls need to be referenced from these sections. Hope this can be of some help to you!
The whole point of installing a screed is to create fall to the drain right? But the floor underneath the screed will always be flat right? So we waterproof under the screed with a correctly recessed puddle flange. But how does this water that has worked its way through the screed to the floor below find its way to the puddle flange, given that the floor here is flat?
thanks for another gtreat video. If your on a second story with fibre cement sheet wouldn't recessing into the sheet (which may only be 20mm thick) potentially be a structural issue? Again where using fibre cement sheeting it is near impossible to create a fall with the sheet itself. Would it be possible to use a very thick membrane so the fall is in the membrane instelf? Or if using membrane above and below screed can you ignore the bottom membrane as fas as the fall requirement and flange recessing?
Hi David, Rebating the flange into the sheet is a question to be posed to the relevant sheet manufacture. No, membrane cannot be used to create falls. Please reference AS3740 in relation to design and application. Happy to answer specific questions regarding products, uses etc. All design considerations and installation compliances must be referenced to applicable sections of the NCC and relevant standards. Hope this can be of some help to you!
@@GripsetIndustriesPTYLtd thanks. I did email James Hardie about this as their instruction manual for flooring is quoting a version of 3740 from around 2010.
Builder i do work for their wetsealer does not recess puddle flanges anywhere. Trying to achieve fall to a smart waste is very difficult. Is there anything in the national code that states puddle flanges must be recessed on the 2nd story bathroom floors
Hi Adrian, the current AS 3740 2021 wet area standard under section 4.3.1 requires leak control flanges to be recessed level or below the substrate. Under Part 10.2 of the ACBC Housing provisions states that membrane drainage connections in concrete floors, flanges can be cast in or set into the top surface of the slab/tile bed, and for all other floors, the flange may be set into the substrate or the tile bed. Both imply the flange is set into the substrate, not on top. I hope this helps and thanks for watching! :)
