Hi sir,
Appreciate your explanations. Would like to ask regarding first floor toilet floor leaking (terrace). What waterproof material shall be suitable to treat the toilet floor without much hassle or hacking?
Tq
To solve the leaking 1st floor (terrace), usually there are two methods to rectify it
Method 1. Hack the entire floor and redo everything[SIZE=7]To hack the entire tiles,
To hack the existing cement sand screed,
To hack the existing waterproofing materials until the
concrete base. Once removed everything, Redo everything. Start with
Supply and apply with new waterproofing materials (Cementitious type),
Supply and apply cement sand screed (gradient/slope surface - gravity high level to low level to allow water flow)
Supply and install new tiles
Above method 1 is always the best solution. However required alot of time and the most expensive method. This method can be use if the water leaking area is too severe or too "complicated scenario" "Complicated scenario like I) concrete profiles full of crackline or full of porosity
II) the existing waterproofing embedded failed miserably
III) contractor forgot/never apply waterproofing membrane at all
Method 2. To inject chemical PU injection to permanently stop the leaking at that particular area onlyFirstly Determine and analyze the leaking area
Then Inject Chemical PU grouting to stop the water leaking area. This PU grouting once react with water will expand form a tight, impermeable, elastomeric seal and permanently stop the water leaking at "that particular area only"
Above method 2 do not required those hassle or hacking. Very straight forward rectify the water leaking.I will update more pictures to explain in more details. Currently busy

what is the cheapest waterproofing way for a small bathroom
Is your small bathroom completely new? The entire floor is "naked'? If so get those "cementitious Waterproofing type will do. Cementitious Type waterproofing is the cheapest among other membrane type (Polyurethene PU, Torch On membrane, Acrylic Polymer etc...) Internal areas can be apply with cementitious waterproofing membrane because internal areas do not exposed the sun and rain.
Exposed area to sun and rain must not apply with cementitious type waterproofing. The reason is over the long period expand and contraction will easily damage the brittle type cementitious waterproofing.

5. Self adhesive waterproofing system
=can diy?
I assuming your self adhesive waterproofing DIY type is pour on the tiles flooring surface and allow it penetrate into the concrete pore? This DIY type depending on the tiles and concrete profile surface. If the concrete profiles surface full of severe crackline / very porosity or the existing waterproofing embedded inside the concrete
poorly apply. This self adhesive DIY won't be effective.
This DIY might work if the leaking is very minor and concrete profiles surface is not severe.
My definition of self adhesive waterproofing type is those apply at large scale project spec by architect. Its not very popular type of waterproofing

how about toilet waterproofing. i know that if hire a contractor do, they will take out the existing tiles and redo the water proofing. is there any way we can DIY and without taking off the existing tiles.?
I think those DIY type is less effective to counter water leaking unless the situation leaking area is very minor. There is another method solving the water leaking without hacking existing tiles and redo the waterproofing which is inject PU grouting. Inject PU grouting is pretty complicated and one must be experienced and skillful to inspect the leaking area to made the best decision. This PU grouting is the most popular method and widely use by the developer and contractor when newly move in house owner complaint their unit is leaking.
I will upload more picture as examples. Hopefully tonight when i am free
