Hi sifu, I recently completed the torch membrane waterproof 3 days ago. Today raining and a little bit of leaking from the roof slab. The contractor informed me that due to the pressure of the rains as the concrete slab is not totally dry yet. Is it true?

any recommendation for torch membrane specialist?

My carporch concrete roof top is having small cracks and the normal waterproofing paint is not really workable although many layers were painted.
i googled and many placed as ads.

size is about 20'x20'

Cheras area.

This is regarding a new house.

The bathrooms have a shower area that has slightly lower floor area and come with shower screen. The floor of non shower area (toilet bowl and sink) is slightly higher.

I pond test the entire bathrooms (two bathrooms with same design 8-3' x 6-3'). The shower area doesn't leak below. The non-shower area leaks below (I come back after 24 hours).

Is this normal? Or is this consider a defect that need to be rectified by developer? I need to ask because as expected, my developer argue that no body flood the non shower area in normal use and I have also void the warranty.

Thanks in advance!

When you said 'dry area' do you mean there is no waterproofing?

It may sounds right at first read. The shower area indeed try to prevent water from shower into the non-shower area. But the non-shower area is definitely cannot be called 'dry-area' because there is a two-way-tap beside the toilet bowl with a bidet and a straight tap where water can immediately hit the floor of this area. There is also a drain. It may not be as wet as shower area, but it still will get wet. And for small bathroom, it can get pretty wet. Just imagine cleaning your feet.

I can understand where you are coming from. 

Hi all the sifu

may i know how much it cost to fix these:
1) roof water leaking
* charge per spot?

2) aircon pipe leaking
Aircon pipe concealed within the wall, So will need to hack the wall to fix

*My bad! I pressed the add reply to the 3 images above and left out my comments below:

Hi all, need your advice as I have this leaking issue, allegedly from my apartment to the unit downstairs that's been ongoing for the last 3 years. My apt is tenanted.

First image was taken at the downstairs unit's bedroom before any repair was done. After the downstairs owner reported a complaint, I engaged a contractor, which was recommended by the management office. Waterproofing was done to my bathroom and issue closed (mid 2019).

2nd image was taken at the same spot by the downstairs unit 1.5 years after my repair (early 2021). The management office this time suspected the leak may be from somewhere else (my planter box unit). Because of covid SOPs etc. and didn't want the issue to drag on for too long, I once again engaged the contractor to do the repair. 

Fast forward to this year, you can see in the 3rd image that the watermark is slowly coming back. Management office contacted me again. At this point, I am not sure what else they want me to do. Plus I recently changed the piping in my unit's bathroom to new ones.

How can I push this back to the management office  so that they do the proper checking on their side rather than just simply forwarding me the downstair's unit's complaints? Could it be that the leaks originate from within the downstair's unit itself (eg. their own piping etc)?

Also, do you have any recommended waterproofing companies? I am thinking of engaging one, to get their opinion.

Thank you.

See the 3 photos are right before my written post. You can refer to my written post for explanations of each photo. No I did not oversee the work myself as the contractor did the work during office hours.

Hi Mini Orchard,

Would you please advise, this "Penten" is applicable to tiles to solve the bathroom leaking problem?

Thank you!

Hi Guys..

Need some help..

Water is seeping in through the edges of the window frame and also below the window itself.

Another issue is that this is a condo and the other side of the window is facing into thin air.

Anybody have any ideas that can help me? or what I should ask when trying to engage a contractor

Hi everyone, recently purchased an old new house - around 10 years old. I am thinking should I check for any water pipe leak before I do renovations. Is it a standard practise? I don’t plan to renovate all bathrooms (5 bathrooms!) hence cannot change the piping. Anyone had any experience dealing with water leak detection? Done a pressure test myself, seems ok but not able to test the pipes coming from reserve tank. In Penang, anyone had dealt with any water leak checking company here? A bit worried there’s a leak after I’ve done renovations.

This is regarding a new 2-storey house

There are 'water stains' at the ceiling of the first floor room at the back of the house. What's the cause of this, roof leaking or pipe leakage? Is this common and is it a major issue

Hi all,

My old houses constantly having never-ending water leaking problem. Water/yellow stain on plaster ceiling. After paint and repaired, same issue different area. Plan to DIY if possible.

I saw some houses have this black piece of paper on their roof with bricks or something heavy on the black thing.

Anyone know what is the black piece of paper call? and price?

Appreciated ur reply.

Old as in 30-40 years.

The house entire roof already changed due to termite 3 years ago. After the whole roof changed, no issue. Just recently a year ago started leaking. I have called roof repair to fix, solved and the issue come again at other area.

So maybe adding those black piece of paper to the affected area able to solve the issue.

I will consider your advice.

Have you engage any roof repair company before? If yes, how is your experience with them?

Any one in this topic mind to share contacts of roof repair man or roof repair company where price is reasonable?

Hi all, advise needed. Looking for a simple and quick method to waterproof the small yard area in my old apt. It's mostly a dry area, except for that small part where the washing machine is at. Downstairs owner is complaining of water dripping from ceiling/my unit just around that area where my washing machine is. I am not aiming for a full hacking & waterproof method yet. Planning to try coating with waterproof paint method first. Anyone here can recommend a brand or any products that you have used? TQ.

Hi all, seeking advice. got water leaking from my unit above. the unit above claimed they tried to patch all they could from above. they want to avoid hacking down and redo the waterproofing and suggest me to paint a waterproofing paint(t200 penten) on my ceiling instead. will this waterproof paint works? do i have to paint the whole ceiling with that waterproof paint?

Hi, I would like to apply the waterproofing coating on top of the concrete roof car pouch. I'm wondering between Bostik AC2 and Pentens T-200H,which one can last longer and easier to DIY? Trying to get rid of the nightmare of seeing water leak from the slab. 
Thank you.

Hi all, I intend to buy a subsales property below market value, but I realized there are water leaking issues in several spots in the car porch area and level 3 of the unit.
Attach some photos here for reference.
I get quote from the contractor that usually helps to repair water leaking issues in that housing area around RM9500. Is this a reasonable price?
Hope you all can help. Thank you so much
