jadee Posted April 8, 2021 Share Posted April 8, 2021 Hi all, I need some help/advise about waterproofing bathroom floor in a condo. As you can see from the photos, I have a tiled bathroom and water is seeping through the floors and walls. The condo management company employee is coming tomorrow to put some sealant down or something. There is no burst pipe or anything, it's just a case of water going through the tile (or grout?) and seeping into the concrete or whatever the walls and floors are made of. If anyone has any experience of what works, what products are good, please let me know. I've been searching on lazada and would appreciate some advise about the best products. Like, is sealant enough? How often does it need to be applied? Is there a more permanent solution? Back home, I remember seeing tins of 'concrete sealant' - like a colorless liquid that you brush onto concrete to stop water going through. I went to home pro and can't see any, nor had they heard of it. My thoughts are that's the problem - the concrete wasn't sealed before the tiling was laid. Thanks for any help!

bankruatsteve Posted April 8, 2021 Share Posted April 8, 2021 My guess is a not so good tiling job. A name brand sealant should help. 1 Link to comment Share on other sites More sharing options...
johng Posted April 8, 2021 Share Posted April 8, 2021 1 hour ago, jadee said: There is no burst pipe or anything Don't be so sure that there is not a leak in the pipes even a very small leak that doesn't register on the water meter can cause big problems, the leak can also come from the waste water pipes ( toilet,wash basin,shower/ bathtub ) that are buried in the walls not being sealed up properly during construction. Also as you suspect, the water could just be from leaky floor tiles which could be ( maybe but not certainly) solved by re grouting the floor. Avoid using toilet cleaning products on the floor tiles as they often contain hydrochloric acid which eats away the grout. 1 hour ago, jadee said: Is there a more permanent solution? Yes but you won't like it as it requires ripping out the existing plumbing/pipework and tiled floor, sealing the floor with an epoxy resin (something like TOA Epoguard 100) re plumbing and pressure testing before laying new tiles... yes a big big job !!! 1 Link to comment Share on other sites More sharing options...
OneMoreFarang Posted April 9, 2021 Share Posted April 9, 2021 I had a similar problem many years ago. The condo repair guy applied sealing (I don't know the name and I can't see it). That was many years ago and I never had complaints again so it seems it worked permanently. 1 Link to comment Share on other sites More sharing options...
jadee Posted April 9, 2021 Author Share Posted April 9, 2021 thanks for all the helpful replies everyone! The maintenance guy came and applied some sort of sealant around the tiles. I'll see if it helps. He mentioned that the grout had gone in some places so that was spot-on advice from johng, cheers. I'll be careful about the cleaning products and see how it goes. 1 Link to comment Share on other sites More sharing options...
