Why leh? What's so special about that place? I drive there quite often
read the other comments, because of all the digging for NS Corridor the underground segment.

the person who drove at the Mounbatten Road/Katong towards ECP will also be thinking the same thing...what's so special...everywhere there's digging/roadwork in Singapore. Ppl/Authorities became complacent until an incident happen.

am I the only one who is surprised by the thin layer of the road?


the actual paved surface (asphalt or concrete) is often just 10–30 cm thick. What really matters is what's beneath it:

Road Structure (Typical Layers)

1. Surface Layer (Pavement)
– Asphalt or concrete (about 10–30 cm)
– Smooth finish for vehicles, but not structurally strong by itself


2. Base Course
– Crushed rock or gravel (20–40 cm or more)
– Distributes load and provides drainage


3. Sub-base
– Lower-quality materials (sand, recycled concrete, etc.)
– Further support and helps prevent settlement


4. Subgrade (Natural Soil)
– The native ground — its stability is crucial
– If this layer is weak (due to water erosion, poor compaction, or soil type), it’s a recipe for sinkholes or road collapse

So if water seeps into the subgrade (via cracked pavement or broken pipes), it erodes the soil or creates voids. And since the road layer above is relatively thin, it collapses eas
ily once support below is gone.

Sent to raffles hospital means is rich alrd… no need you to worry.
You’re probably not aware that there’s an existing arrangement with Raffles Hospital for some emergency SCDF cases to be sent there. It’s known as Emergency Care Collaboration (ECC). Patients staying in shared 6-bedders rooms will be paying the same as subsidised patients in restructured hospitals

My guess is that the tunnelling access shaft for PUB work (in red) caused some soil movement, which ruptured the water mains pipe (in blue). The gushing water from the ruptured pipe then displaced a large amount of soil, accelerated the creation of the sinkhole. The freshly repaved road was probably just a temporary but ineffective patch over an underlying issue that hadn’t been properly identified and fixed. I also won’t be suprised that there were telltale signs like increased water/soil ingress into the access shaft (in red) recently due to the ruptured water mains but this wasn’t seriously taken as a warning sign

earlier i started a thread on japan sinkhole and tried to warn sinkhole problem...
cos saw in one of the videos, the comment section someone say sg same same as japan...
https://forums.hardwarezone.com.sg/threads/japan-sinkhole.7140787/

What do you mean that you tried to warn sinkhole problem?

The title stated Japan Sinkhole and you made 3 posts without any additional text or inputs stating your point.

So are we supposed to assume that you are alluding to an issue in SG?
