Dear TS,
I have leaking underneath bathroom slab in my brand new house. The contractor said there is some crack underneath the slab that causes the waterproofing to fail. So he suggested PU injection to solve the problem. I refuse to have PU injection because there is electrical wirings inside the false ceiling and wiring + combustible PU is a fire hazard. He said that even if we redo waterproofing, the problem will persist since the slab is crack.
My question is, is it true that redoing the waterproofing + retiling wouldn't solve the problem? Or he is just trying to trick me to agree with cheaper solution?

QUOTE(PaintPals @ Jan 21 2021, 01:20 AM) Cementitious Waterproofing + retiling should be able to fix the problem. This kind of contractor better avoid, PU injection in this case is a big NO NO. Thanks. I cannot avoid the contractor because they are developer’s contractor and the house is under DLP. But then of course I don’t trust developer’s contractor because I know their solution is to find cheapest way to hide the problem until DLP ends  |

QUOTE(ceo684 @ Feb 6 2021, 06:11 PM) Ahh then it is on your responsibility to fix already. The more futureproof solution is to hack off all the tiles and redo waterproofing layer and retile (if its leaking from the tiles area). If its leaking from the WC drain pipe outline (got gap between the drain hole and the drain pipe) then its a smaller fix. The temp fixes like PU injection or simply redo grout doesn't solve the root cause that allow water to seep in through the untreated floor slab. Then MO or neighbour will ding dong ur doorbell again to complain. Yeah. PU injection is definitely a short term solution. In the apartment I stayed last time, problem reoccured after 8-9 months of injection, then inject again, then happened again and again. In my current house, developer do injection as solution and in most houses, problem reoccured again after 6-7 months. My unit, I insist them redo the whole waterproofing. The original waterproofing was so bad, both my toilets upstairs leaked This post has been edited by blanket84: Feb 7 2021, 01:00 AM |

QUOTE(hirano @ Jan 27 2021, 09:59 PM) I'm not sure why. Only after 1 month staying in new house (just developed), the bathroom white grout changed color to grey cement color? Not sure if developer took shortcuts with cheap materials. Want to re-grout the bathroom now. Between these 2, which is better to buy?  The 2nd one is definitely not amateur friendly. I tried to top up some missing grout in my kitchen and it took me few hours to complete a small section using powdered grout The first one seems more user friendly. Alternatively, you might consider Mapei Fuga Fresca (which is like school shoe’s chalk in old days) or Mapei Grout Refresh (might not be available in Malaysia and have to buy from Amazon). |

QUOTE(samsungfreak @ Nov 7 2021, 11:06 AM) It may sounds right at first read. The shower area indeed try to prevent water from shower into the non-shower area. But the non-shower area is definitely cannot be called 'dry-area' because there is a two-way-tap beside the toilet bowl with a bidet and a straight tap where water can immediately hit the floor of this area. There is also a drain. It may not be as wet as shower area, but it still will get wet. And for small bathroom, it can get pretty wet. Just imagine cleaning your feet. Just file the defect report and ask them to redo the waterproofing. Here in Malaysia the whole toilet supposed to be the wet area, unless you're buying fancy big house where your wardrobe is also part of your toilet. My housing area had the similar issue, the developer has to redo the waterproofing in almost all houses in my taman since almost all of them failed.
