I saw a lot of little airhole in my ceiling.

What went wrong during the process in building my unit that result in this?

In term of safety standard, are the compliance to regulation?

Thanks in advance.

Can post a photo of it (the "air-hole" you mentioned) here? How big and how deep is it? Can it be patched up with cement?

Have you started renovation yet?

Perhaps go query HDB or your nearest Town Council to rectify it for you, before you even start renovation. Or else, they will say it is your contractor who caused it.

Just my opinion.

those prefab HDB are just like making cake, mix everything together and then pour into a mould to harden. During mixing bound to introduce bubbles. U can ask HDB to plaster them for you.

it ok with me with explanation.

If it ever had any conflict of safety, then it cannot be compromise.
