Waterproofing but still leaking - Sometimes it's not the material!

1. Thought Waterproofing Was Done - Who Would Have Thought It Was Leaking Again

You buy genuine materials, follow the instructions.

The technician has scanned 2 layers and sent back a photo.

But then a few months later... the walls started to turn yellow, and the toilet floor leaked water to the floor below.

"What kind of waterproofing still leaks?"

The answer sounds so real:

The fault is often not in the material - but in the way it is used.

2. Typical Mistakes That Damage Waterproofing Layers Even If The Right Materials Are Used:

- Not cleaning the surface thoroughly before construction: The waterproof layer does not adhere and peels off after a few months.

- Construction when the surface is still wet or too dry: The material layer does not adhere well and absorbs water back.

- Do not use a bonding layer of oil: The coating does not adhere firmly to the substrate and is easy to separate.

- Do not treat weak points: pipe collar, wall base, stop joint: Water seeps through the gap, causing seepage even though the floor surface has been treated.

- Wrong construction process: wrong mixing ratio, applying too thin a layer, not waiting for it to dry enough: The waterproof layer is weak, easily cracked and blistered.

3. Waterproofing Construction Not Only Requires Good Materials But Also Knowledge, Experience And Experience

Waterproofing materials are aids, but the installer is the one who determines the results.

- Failure to follow correct mixing ratio.

- Do not process the wall base/pipe collar.

- Not understanding whether the material needs to be moist or dry before construction

The waterproof layer is just a membrane waiting to crack.

- Check humidity with equipment or experience.

During construction:
