Injected PU Fillers Into The Ceiling

I dislike stains on the false ceiling. That means there's water leaking in from somewhere. The stain on the false ceiling in the kitchen first appeared in 2023, then 2024. I know this wouldn't be a leak from the pipe. The rate is too slow. Last year, I had newspapers in the false ceiling that I changed every six months. By this year, it would be the third year that the leak came through. I needed to do something about it. Water leaks can't be wished away. It could only get bigger. I don't want anything to burst and collapse. 

The AC crew took a look and declared it isn't a leak from their pipes. My own plumbers came in to take a look in 2023 and 2024. In 2023, they couldn't really pinpoint where the leak came from. They wrapped up the pipes and see if that would resolve a minor leak. In 2024, we were sure it wasn't the pipes. My plumbers finally diagnosed the issues after many checks and elimination. This is in no way explained by humidity and condensation. There are already stalactites on the raw concrete. LOL The seepage is slow. They could attempt to fix it by injecting a PU filler, but if this involves the discharge pipes and concrete ceiling and waterproofing, then this is under the purview of the developer and Main Contractor (MainCon). 

After much procrastination, I sent a query to the MCST in September. I didn't know if it might involve the unit upstairs (co-payment or something) or minimally what the neighbors might need to observe/check on their part. So I wanted it all to be recorded. The maintenance crew and even their contracted plumbers came in to take a look, and the MainCon's plumbers too. Like five times. They arrived at the same conclusion as my plumbers. Of course lah — they're all professionals and they know what they see. The MainCon's plumbers have seen this play out a billion times. 

I am very fearful of leaks in the home. It's like an obsession and it keeps me up at night. I need to get a full picture and see what's going on. Talking to plumbers and the contractor might not tell me the full picture for the situation, viability of the fix and future issues; if I asked more questions, they might get annoyed. I only have a 'SkillsFuture plumbing maintenance 101' understanding. So I checked in with ChatGPT. I'm somewhat assured that this fix will hold for a bit.

The entire estate is still under the developer's 10-year warranty. I'm just relieved that it happened at this time so that I can get it rectified. At this point, this is indeed a matter for the MainCon to sort out. Water is leaking from the concrete ceiling from the discharge pipes somewhere in the stack or from the upstairs unit. The waterproofing isn't holding up. No payment necessary on my part this round, but I get all the fun of cleaning up.

The false ceiling had to be cut open again. Repair works weren't too messy. It was half a day's work. But still. Ugh. I had to laugh. The suggested Saturday date of injecting concrete fillers was right smack on our wedding anniversary. I sent the dog away to her aunties, sent the husband to the gym, and I got a good workout cleaning up. 

There're so many water issues in this flat. Oh well. It could have been worse, really. Ahhh... the joys of owning a home.
