you need to re-do new water proofing for both area above.

problem could the contractor fix or not, worry it leak again after I put in the plastic ceiling.

The joint is not properly done... A lot of Renovation Contractor has no proper knowledge of water proofing.. Actually all jointing area shall be formed with Angle Fillet prior applying water proofing..

bro i think after contractor fix/water proof will also leak..mine is something like this too.

regarding my case, as i dont have money to demolish and rebuild, i do ajiya awning, it fixed the problem, but in very very heavy rain i can see 2-3 small water mark.
recently i cleaned the roof, clean away dust etc, paint the whole cement roof with undercoat and then paint. hope it will do. considering to put bitumen stripes around the roof sides/lines later

Bro,

a) Based on the above scenario, your RC Flat roof is sitting on existing wall/beam right? My question,

did your SC roughen the existing BW/Beam surface,
did he clean it after roughen the surface and
finally did they use any bonding agent prior pouring the Concrete of the RC Flat roof?

Sorry, your questionis to?

To both of you...

What is"Angle Fillet"?

The join between the slab and wall is 90deg, but with Angle Fillet it go 45 deg.

This morning heavy rain and think get worst, hence engage my tile contractor and seem advice, and they will do

1) hack small part of existing floor (near wall)
2) Apply 2 layer of Water proofing "FLESEAL 200"
3) Apply one layer of sand / cement (Up to low), so that water could exist more fasted
Option: If still have balance water proofing, will than another layer, as I puchased the 20KG...

All this will minus of from the old contractor $$$ that still hold by me.
As I guess he also out of idea or knowing he in big trouble, hence agreed to let other people do...

Take sl2007 advice, make Angle Fillet. Than apply the sealer.

WHere could I get this so called "Anfle FIllet" or meant of doing a 45degree a slope through cement?

the angle fillet is done using cement screed. This is to drain the water from the edges

The Indo is making a slope but not really 45degree, it more like 25-30 degree, and I have a filling that they will able to solve the problem, since they check the root cause and saw the leaking when they doing my roof work...
