Browse Forums Building A New House 1 Dec 11, 2013 9:20 am Hey all experts, We have just visited our site and had a good chat with our site supervisor about the water proofing. I am particularly interested in learning how that's done for double story bathrooms. For us , its just the shower wall and flooring around shower. That's it! Absolutely nothing in or around spa and bath hobs in our en suite and bathroom. Site supervisor says that they use special water proof plaster on walls, but still does not answer how that water proofs the flooring. I am too scared to think what would happen in case of any water damage to the underlying timber flooring. Also according to BCA standards I just read that they need to water proof entire flooring in the en suite, not just spa /bath, not just the shower but entire en suite flooring and also balconies, upstairs. Could somebody shed some light on this urgently please? I really need to get it clarified before they out tiles on, and that's not too far away!! Re: waterproofing upstairs bathrooms - is this OK? - Urgent 2Dec 11, 2013 12:45 pm I remember in an old place of ours we had a fibre glass sort of floor put in the shower area - to ensure it was water proof - ie under the tiles. Water can get in anywhere - go uphill, and can find the smallest crack. I'd be worried if all I had was a tiled floor with grout between them. Is it a suspended slab ? Re: waterproofing upstairs bathrooms - is this OK? - Urgent 3Dec 11, 2013 3:46 pm Hi, You really need to speak with your Certifier as to whether the waterproofing inspection has been completed. Also notify them of your concerns re not meeting the Building Code, take photos and email the Certifier so that it is well documented. If the inspection hasn't taken place then all should be good - your Certifier is aware they can't pass it until it meets the Building Code. If the inspection has taken place they may have passed it because they were unaware that there was still to be a spa bath installed but I can't see how they can avoid waterproofing the floor?. We built a double storey and the floors in the bathroom and ensuite were definitely fully waterproofed.

She also said that water proofing is not something that they would not compromise for their homes. But she does not have any information as to what that alternative solution is, though. She said this is covered by a 10 year warranty and they will need to fix it if it fails before 10 years. Hope that's true. Looks like not much I can do anyway, as they say I have signed the contract / building permit which mentions about this alternate solution already. Re: waterproofing upstairs bathrooms - is this OK? - Urgent 5Dec 12, 2013 2:50 pm Screw that ! Alternative solutions can be as lame as placing a bucket under the leak downstairs when it happens not if. I'd be jumping up and down and screaming bloody murder if it was my place. Stewie Re: waterproofing upstairs bathrooms - is this OK? - Urgent 6Dec 12, 2013 4:27 pm I am afraid you're fighting an uphill battle here. Not sure about other states, but in Vic I've yet to see a project builder who waterproofs the entire bathroom floor regardless what the BCA says, mine didn't. I have free standing bath tubs, the only thing I have is a cement sheet under tiles.

Not saying it doesn't exist but in my understanding the other rooms have plasterboard while wet areas have cementboard like Villaboard which is more water resistent than plasterboard but still needs waterproofing. If she said "special water proof plaster" I'd be asking for a brand name.

There's a horrible creepy familiarity about that sort of scenario. My admin replied back to me saying that , they have an alternative solution in place and that is approved by BCA and building surveyer. Get it in writing, detailed writing. She also said that water proofing is not something that they would not compromise for their homes. Would she say anything else? (Apart from the double negative.) But she does not have any information as to what that alternative solution is, though. Get it in writing. Love it when they have such faith in stuff they don't even remember the names or details of, but then it's not their house, they don't have to live with it, they just have to spruik it. She said this is covered by a 10 year warranty and they will need to fix it if it fails before 10 years. Get it in writing. Not sure how much it helps though. Getting them to say they will do something about any problems is one thing, getting them to answer their phone or to make an appointment to come to your house or to actually turn up is quite another. But I reckon it's worth it for the message it sends them about how serious you are. Hope that's true.
