Re: Waterproofing to wet areas - Minimum standards help 5Aug 04, 2016 6:15 pm I'm stumped as to why builders and tilers perform these works to a minimum standard. If the floor is concrete or compressed fibre-cement sheet: The floor needs to be of a water resisting product, i.e porcelain tiles etc Although some would say that option isn't exactly water resistant, but it passes. The tiling in the shower needs to be min 1800mm high. If it's an inserted bath (off the wall) then it requires waterproofing to min 150mm above lip of bath and waterproof junctions within 150mm above bath. Waterproof tap and spout penetrations where they occur in horizontal surfaces. Re: Waterproofing to wet areas - Minimum standards help 6Aug 04, 2016 6:27 pm They are wrong concerning the walls in the shower. AS 3740 2004 Waterproofing Standards Table 2.1 The shower area is regarded as an area of high level of risk which means Floor - waterproofed and drained Walls - water resistant Junctions - waterproofed Penetrations - waterproofed Under the definitions in Section 3 - Materials 3.2.2 Water -resistant Substrates a) Walls (ii) Cement render treated to resist moisture movement. Unless the plasterer has added a moisture barrier additive to the mix he rendered the bathroom walls with then it doesn't meet the standard. The floor in the shower is done correctly ( they have returned it up the walls 150mm as well ). Outside the shower in the rest of the bathroom - no. They don't have to waterproof the floor but they do have to waterproof the floor/wall junction which they haven't done. Stewie Waterproofing to wet areas - Minimum standards help 7Aug 04, 2016 6:49 pm Stewie, the AS3740-2010 seems to supersede the 2004, I couldn't find some of those things in my book so maybe they have been deleted.
I also have the amendment 2012 to the standard. I'm not sure if there is another amendment currently.. Forget the minimum just waterproof the whole shower floor, waterproof the whole shower walls to 2m, waterproof the whole floor regardless of material used, come up the wall/floor junctions outside the shower at least 150mm etc. The client has peace of mind and so too the builder for the next 10 years Re: Waterproofing to wet areas - Minimum standards help 8Aug 04, 2016 7:15 pm SaberX Given I'm concerned but not sure if minimum standards are left, but am not attempting any defamatory action against them - would I be ok in even posting the builder name? It wouldn't be defamatory if they have used an Alternative Solution...now called a Performance Based Solution. These are being used by more and more builders and is the reason I asked the builder's name. Check the thread currently under this one. 3in1 Supadiverta.

That's the way we have always done it too regardless of the materials used for the walls and floor. I was just quoting what is in the standard. I should update my copy too.
