Browse Forums Bathrooms and Laundry 1 Sep 15, 2008 2:03 pm We have a Queenslander style house and on occasion two bathrooms have dripped water through the floor to underneath the house. (ie: kids splashing water out of the bath etc - not excessive amounts of water though).
We want to raise our Queenslander and build underneath, and obviously need to fix this problem before that is done. Is the only way to rectify this problem by tearing up both bathrooms and redoing floors etc? Anyone got a ballpark figure for this type of work? We are hoping to keep current vanities, bath, etc, and tiles are standard and simple (ie: nothing flash). thanks Re: Bathroom Waterproofing (rectification works) 2Oct 23, 2008 7:48 pm We have already completed the job you are talking about. I am assuming that you have wooden floors in your bathroom? We did and we had to lay tile base - I think it was a villaboard tile base (available from Bunnings) down first and nail to the floor boards. We then had to have this waterproofed - we got this done professionally and cost around $500 for 1 small bathroom/shower recess. You can also do this yourself; Bunnings sell waterproofing product and it is really easy to just paint on (2 coats), however, you wont obviously get a certificate from the waterproofer like we did which may be important for resale down the track.
Following this, you need to lay a mortar bed at lease 50mm high, and work it so your floor is sloped towards the drainage. Then once this it dry you can tile over. It is a bit of a job to take on as a diy. We did and had never done it before and it was really quite difficult - but it looks pretty good. Best of luck. Re: Bathroom Waterproofing (rectification works) 3Oct 31, 2008 10:19 am HI,
I am about to start reno's on my bathroom and was wondering when i waterproof the floor and walls do I do that over the villaboard and then tile over the top of the waterproofing or do I put it on the floorboards then place the villaboard on top. As you can prob tell I am not very Knowledgeable. If at first you don't succeed, try, try again. Then quit. There's no use being a damn fool about it. W.C. Fields Brought Established. Re waterproofing bathroom 5Nov 25, 2008 3:28 pm Hi there
Villaboard is actually a wall lining, not to be used for the floor. For the floor, there's actually a new product out called Secura wet area flooring (find out more here http://scyon.com.au/secura_wet.html), which is able to be cut like timber, nailed with a nail gun (if you have one!) and is tongue and grooved. You also don't need to waterproof anything other than the base of the shower itself and the wall/floor junctions. If you want more info about disaster-proofing your bathroom, you could check out these two artciles at http://www.lookhome.com.au (or just subscribe and they'll send you the free mags).

Re: Bathroom Waterproofing (rectification works) 6Nov 25, 2008 6:48 pm Hi Renovation Survivor,
The product you are talking about sound great! Wish we had known about it when doing our bathroom! I am aware that vilaboard is a wall product, but they also make a special tile sheet. I understand what you are saying about doing the shower base, however, if the house in question is a Queenslander and has floor boards (as opposed to slab) it would need to have a waste fitted in the floor in case of excess water etc. The floor needs to slope towards this waste (excluding the shower obviously as it would have it's own waste). This is the standard as per Brisbane council and the whole floor needs to be waterproofed. Having said that, I just checked out the product in question, and it does specify that the whole floor does not need to be waterproofed. I would, however, check that this is the case with timber flooring, as the article didn't seem to specify. Perhaps the original poster should check with council or a plumber as per regulations. I personally wouldn't skimp on waterproofing when you consider the possible disasterous side effects. Re rectification 7Nov 25, 2008 6:58 pm [quote="sambo"]Hi Renovation Survivor,
I am aware that vilaboard is a wall product, but they also make a special tile sheet - actually no, sorry. Villaboard is ONLY a wall lining. The floor products are Secura, compressed and CTU. But Secura new and fab. I understand what you are saying about doing the shower base, however, if the house in question is a Queenslander and has floor boards (as opposed to slab) it would need to have a waste fitted in the floor in case of excess water etc. The floor needs to slope towards this waste (excluding the shower obviously as it would have it's own waste). Of course - what I meant was it does need to be waterproofed in the enclosed base of the shower - in any jurisdiction including queensland - but it only needs to be waterproofed at wall junctions elsewhere. By timber flooring outside the shower, do you mean instead of tiles? If anyone's interested you can ring for technical help at 11 13 03 I think. cheers Who does the waterproofing 9Nov 27, 2008 3:15 pm You should get a licensed waterproofer.
Cheers (definitely NOT a plumber) Re: Bathroom Waterproofing (rectification works) 10Nov 27, 2008 3:51 pm Look up waterproofers in yellow pages or your local paper. Not cheap - cost us around $500 for a relatively small bathroom 2 + years ago. If you have a plumber he likely knows and may even use a waterproofer himself. Worth it for peace of mind I think, and when you resell, some people may ask for waterproofing certificate which a professional should give you.
Best of luck. Re: Bathroom Waterproofing (rectification works) 11Dec 08, 2011 1:24 pm Hi, I am a licenced Waterproofer and also have a licence in Floor and Wall Tiling. I would recommend using Tile Underlay on your floor and because it is a Queenslander that is going to be raised I would definately bed the floors put in a waste if one is not already present. When waterproofing remember to prime the area that will have the membrane applied to it and use the correct primer for that membrane which will be used. Make sure to use a bondbreaker something like PU Sika or a neautral curing silicone depending on the product you are thinking of buying I could recommend some products if you like. Apply the bond breaker of choice to all vertical and horizontal joints, install any angles that are required like door and shower angles which the shower angle needs to be there whether you are having a shower screen or not and depending if you are having a shower screen or not will determine whether the angle is exposed or not. Shower internal joint should be done 50-100mm above shower rose, bath joints 200-300mm high if required, all perimeters need to be done and any other joints in the shower, I also like to skim over any nails in the shower area. remember to smoothe over the bond breaker, again I like to use a paint scrapper. Allow to set which depending on the bondbreaker will be the time factor. Once skinned the membrane is now ready for application, for best results I have found that if you paint brush on the membrane for all horizontal and vertical joints and roll on the membrane for the floor area once in one direction and for the second coat in the opposite direction to lock it all together you will have no problems in the future also make sure the finishing height for your perimeter is no less than 25mm above floor finishing height. I am pretty sure I have cover everything and if you need any advice in the future I would be more than happy to help. Good luck. Hope this helps. BTW:Waterproofing Certificates do have there purposes both for resale and for insurance. Re: Bathroom Waterproofing (rectification works) 12Apr 18, 2015 6:53 am Thank you for these explanations. The waterproofing certificate will have use for reselling , but will probably be of no use for insurance. Insurers will not cover you if the waterproofing membrane is damaged.
