If water mark exist, even without ponding test the developer should repair it.
Anyhow, it is good to know that your developer have agreed to repair it for you.

If really 5mm gone in 1 hour and no sign of leakage, probably the reason will be the floor trap is not properly sealed.
FYI, if after ponding test there is no sign of leakage then your bathroom not likely will have waterproofing problem as when you use your bathroom, you will not pond it.
And i don't think water can affect a proper cured concrete much.

Developer was trying to avoid repair, to be specific, the sub-con that was doing defect rectification tries to avoid as much repair works they can.

This photos was submitted for defect claims, but was rejected by defect team...

Water mark at ceiling of downstair room:


Water mark also can be seen at side wall of bathroom:

This is a clear water seepage that developer must repair.

Can kindly pm me or post the developer name here , this is a very IRRESPONSIBLE developer we all need to be wary.

T****N IND*H from northern region

is there any ways to check leakage for condo units? i think not all owners, especially those investors would do leakage checking..

anyone who is living in condo, could you share your experience when you got your unit? many thanks

Just do a visual checking, look for water mark. Especially during heavy rain day.

For water seepage at bathroom side wall, what type of repair can be done, beside hack off tiles & redo water proofing?

As i know that shoild be the way.
Either from internal side or out side the wall.

Developer repaint & redo ponding test, now my bathroom side wall looks like this:



Very sad......

Ask them to repair the wall surface and repaint it.
Then further monitor for water seepage.
And FYI, waterproofing contractor is giving out 10 warranty to the developer.

my_nickleo, u can submit the developer an inspection report with photo showing the defect clearly and then give them 2 week notice if no rectification done within another 2 week, u will bring the issue to Tribunal for Homebuyer under national housing board of development and concurrently u will engage ur own contractor to submit the quotation to developer for the rectification work. If the development no action taken then give them a notice that u will start the rectification work after and back charge to the Vendor's solicitor (which bank pay to the lawyer to hold the retention money for the warranty purpose).

I use this way to force my developer to rectify all my complaints. Any non compliance still can claim to the Vendor solicitor BUT make sure is not exceeded 8 months they hand over the key to u. Do read thru the S&P agreement then u will know where u stand on ur own right.

I strongly suggest u force the developer to hack the entire bathroom floor then redo waterproofing and retile the floor again. As this is the proper rectification method and it can last longer and avoid for future leak.

How to do the water ponding test?
Use tape to seal up the floor water trap?
what kind of tape ?

hi guys, sorry for reviving old topic. I am having issue for my condo water ponding test. I seal the drainage with masking tape and put on 3kg heavy object. Flood the area and i was there observe around 1 hour before i left.

Today i went to the unit again, the flood gone and i notice there are some water in the drainage. Does this mean there is water leaking or i didn't done the sealing well.

Was trying to contact my neighbour downstair to check the ceiling but they are not available

masking tape is a very poor choice.

first time doing, dont know what should i use

any recommendation?

Use same diameter pipe and silicone the edges?

Is there a guideline for architect to follow when carry out ponding test before sign as acceptance? The ponding test is to do only at wet area (showering area), or both with the dry area (basin & wc area)?

A ponding test is done by sealing up all drainage exits in the area and flooding the entire area with 1-3 inches of water. The test may be carried out for a period of 24-72 hours depending on the situation.
Observations on the water level should be steady without any wetness on the outside wall and bottom floor (one floor below if more than one storey)

Should be both basin & wc area as long within the bathroom floor being wet area thus would be exposed to standing/ponding water by the user.

Installed bathroom tiles and grouting compound must be waterproof.

You can also add in a layer of waterproofing membrane if required to the manufacturer's installation guidelines
