i may have been a bit rusty with my concrete knowledge

erm... an easy analogy

put a plate on top of a glass of hot water (like u said, curing concrete release heat)

you will see condensate droplets on the bottom of the plate (the 1st floor slab soffit)

i know it's a bad analogy, but i am also interested in the source of the water droplets on the soffit.  smile.gif

More like how rain clouds are formed?

same principle.. remove the heat from steam you will get water..

Water condensation always forms on cool ambient.. also known as dew point..

Moonhowler,

I chance upon this thread, and hopefully u can help me out.

I'm currently extending my backyard yard to a wet kitchen, and the current progress is say bout 70% done. Roof tiles are the large cement(or clay) corrugated kind, and ceiling are plaster ceiling. There isn't any insulation in between.

The issue is we found moisture/condensation spots on plaster ceiling joints on a few spots, and we thought it was due to roof leak. Efforts has been done to seal the roof even more, with bitumen tape i think, hopefully will stop the issue.

However, since laying the wet ground cement (prep for tiling) yesterday, this morning i found the condensation was more severe on the ceilings, especially the usual spots..and i found out it might be a condensation issue instead of roof leak, when i wipe the inner windows and its all damped. Usually I close off that area during the evening and night, so no ventilation movement, and i can feel its very humid with heavy masonry smell.

Now, i am leaning towards this might be a condensation issue due to the wet masonry works that's not all dry out, and bad airing practice i have been doing at this phase.

Does anyone faced this kind of issue before, and hopefully can enlightened me, as me and my contractor are still puzzled. My contractor is those China-man self employed kind, so i suspected he isn't well versed on this condensation matter as well.

Next phase I will try hoisting the new roof with pipe water to chk if any leakage from roof, so i can rule out the roof.

Its a nightmare for me at the moment, not knowing what shit is gonna come down the road due to this water/leakage/ condensation issue.

Can do some initial investigation first if not sure. Any raining that particular day?

To check whether its condensation or leaking at the plaster ceiling. Maybe you can ask the contractor to cut that area of moisture / condensation spots on plaster ceiling and allow few days to monitor any minor leaking?

If condensation, just install exhaust fan could easily get rid of the bad ventilation humid air.

Instead of hacking, what about epoxy waterproofing flake coating option?
Any pros and cons?
*
Good question about this method

This method is suitable if the tiles bonding with the concrete surface is still solid intact. Because this application method is applying on top of the floor tiles surface.

Those floor tiles with alot of hollow sounds (when you knock the tiles), eventually will come off in the future. The hollow sounds happen because the bonding between the floor tiles and concrete surface is no longer intact. The epoxy waterproofing flake which applying on top of the floor tiles will come off together too. Leaking occurred.

Epoxy flake waterproofing final layer is apply with a transparent liquid chemical call Epoxy. This final layer might be slippery to some people and there are few cases ppl fall down. This is better to avoid if you have old man might using that toilet shower area.

Another bad thing is if you have very nice color expensive floor tiles, this epoxy flake waterpoofing will apply on top of it and you wont able see that beautiful expensive floor tiles anymore.

Pros
This method work if the tiles flooring still strongly intact with the concrete surface. No hollow sound at all.
You can have them create few design pattern.
If you have a bad looking tiles, this epoxy flake waterproofing will cover it and makes it better looking smile.gif

Recently i found a contractor using another more or less similar method like Epoxy flake waterproofing but without apply epoxy final layer. I will try ask him more details his method and some photos to update here. The finishing pretty nice too.

Hi Guys, ask me anything of Water leaking / Waterproofing. The more complicated the question is, the better.
Wondered if you can help me on my water leaking problems at my car porch.
My car porch have a flat concrete slab, and during heavy rain, the water will slowly drip through the concrete and onto my porch.

When I go above to check, i noticed cracks on the cement slab which may be the cause of the problem, especially near the edges (refer to picture). Note that I have done cementious waterproofing, and also coated the surface with epoxy resin, but that only lasted for a year before that gives way.

Would like to ask what can be done, and if we can do PU injection to stop the leaks. Or perhaps torch applied bituminous membrane ?

Appreciate if you can advise on my leaky problem...

My other tenant house has toilet leak issue, about 30qft. Get a contractor check, 1st method hack cost 2.5k, 2nd method apply Epoxy (not flake type), 3 layer, floor and wall (4ft), RM800.

My water leak only happened after 5 years.

Doe applying grout sealant solve the toilet leaking?
I plan to DIY instead of applying the Epoxy

May I know how much the grout sealant cost and what type of grout sealant I should look for.
And what type of Epoxy and cost to use if plan to apply.

Thanks for advice.

I semi-retired doing waterproofing work already. Hahaha!! However if you want a truly specialize waterproofing contractor around klang valley. Those only do waterproofing and rectifying water leaking. I could share their contact number here. I can find my old specialize waterproofing contacts at Johor and Penang area too after i ask their permission. =)

I classified two types of waterproofing contractor.
1) A waterproofing contractor specialize doing commercial big development project (example: Shopping mall, Condo etc)
2) A waterproofing contractor specialize doing only residential house (example: house toilet, shop toilet)

I will share their contact numbers here after i get their permission. Because some of them are attached to manufacturer waterproofing plant.

Its finishing using those typical pebbles type and he did a very slope. Water flow down to downpipe very fast leaving the area floor dried up very quick. Due to pebbles rough surface, its not slippery at all.

I will explain in more details his method on my next post.

Hmm.. The waterproofing products is wrongly used. Never use "cementitious waterproofing materials" apply at external area that exposed to sun and raining (roof, balcony, swimming pool).

Cementitious waterproofing materials can only apply at internal area like (internal toilet, internal kitchen etc). Areas did not exposed sun and raining.

Torch on membrane is good but expensive. And make sure the surface area has good slope. Water ponding above torch on membrane in a long period will peel off.

Attached Image Attached Image

My advice apply those exposed waterproofing membrane acrylic copolymer design against sunlight and UV resistance. The finishing will be waterproofing membrane (grey color) embedded with fibreglass sandwich in between waterproofing membrane. Apply minimum 3 - 4 layers waterproofing membrane because this is external area.

All development project using this type of design waterproofing method if architect specify exposed waterproofing at roof top. Waterproofing manufacturer usually recommend this method.

Epoxy resin eventually will wear out apply at external area due to raining and sun especially our tropical country. Within one year wear out most probably a very thin layer apply at the surface only. =)

In my experience grout sealant will not solved. Even if solved, the leaking will come back very soon. Grout sealant wear out very soon. Curiosity you mention 2nd method apply epoxy (not flake type) is it something above picture i post?

Hello,

my first floor ceiling was damp/ and water was seeping down the corner. Contractor came and checked and said have to hack wall as suspected pipe abs leaking. Upon hacking found abs pipe not leaking, infact no idea where leaking come from. Now found out that neighbor next door is having leaking right at the same spot so the leak may infact come from her side huh.gif

Q1: should i seal the wall or wait until leak is confirmed from neighbor?
Q2: should i just change the abs pipe anyways since already paid for the job?
Q3: if i ask someone to check and give quotation, do i have to pay anything if i dont hire him?
Q4: should i ask compensation from neighbor for the leak/damage to my house?
Q5: what happens if we cant find the leak from neighbor's house as well? Any ideas?
Q6: typically what would be the cost of this kind of service?

when there is construction joint, usually they will be grout tube inside.

My questions is it is we always have to inject the acrylic gel into the tube after the concrete completed. or it is only inject the gel when there is water leakage.

this is scenario base on construction stage.

Hi sir,

I suspect my newly bought condo unit to have some water seepage from shower to the wall. Paint on the wall right outside the shower area have some bubbles / wet mark. The wall is dry now as bathroom have not been used for a year. Switched on all water pipe for 2 days and wall still dry hence i believe piping still ok.

Any services that you can recommend?

Many thanks.

is this New Condo like BRAND NEW or you just bough a resale unit?

which area of wall outside shower area is leaking? wall inside bathroom outside shower area?

usually wall waterproofing only until few inch from floor, the rest of the floor usually use tile to cover. even with waterproofing the normal paint used indoor may not be suitable for wet environment and should use waterproof paint used mainly outdoors, or maybe add a sealant on top of the paint.

when water sips in from surface and cannot escape bubble starts to show.

if got photo easier to tell.

It cost me rm970 for this small toilet.. and I can get it at rm800 if the epoxy is just of a single color.. This price is for toilet below 30sqft. It's been 2 months now, and I still dont see any leaking.. Phewwww.. what a relief.. Looking from far away, the pattern looks nice, but when looking closer, it's farrrr from perfect. Not as beautiful as the one I saw in a hotel.. The lines/pattern boundary are blurry ... lots of color.. how do i say it, color bleeding? something like that..
