Hi, I wanna seek advice on what to do with the leaking probs in my house... really headache, dunno what to do. Dun understand technical stuffs either.

I have 2 spots leaking at home that needs rectifications. This was due to terrible job by developer. I have given up lodging complaints as the problem persists despite XX times they try fixing it, couldnt solve the prob.

First spot: leaking at the car porch... the reason I suspect is due to cracks on the roof... see pics below...






2nd spot: water marks on plaster ceiling downstairs... leaking from bathroom upstairs. There are some pipes hidden in the plaster ceiling, unable to open up and see. So, not sure if it’s waterproofing issues or piping issues...


Should I engage plumber or waterproofing specialist? What are some solutions I can look into? Any advice would be appreciated... thank you very much in advance.

I have a leak going into my lower floor neighbour.

It is seems to leak from the floor slab.

I already did the epoxy flake coat in my bathroom. So seems that the leak is from internal and will need PU injection? How much will it normally cost?

Hi
I got leaking at vertical wall
Inner wall is inside house
Outside wall is open area
Got a small horizontal crack at outside wall
Is that the reason water come in ?

Also can i use epoxy paint to cover it up ?
Can we put normal paint on top of epoxy paint ?
If cannot, what other way to hide that epoxy (eg. Put 1 thin layer cement on epoxy then sealer then paint ?)

But i belip this is temporary coz it'll crack again
Heard epoxy is very hard diff to crack

This elastometric product u apply to indoor walls or outdoor?
