Tiles laid to falls where water must drain, and bedding is full
Why — act while you have leverage
A bathroom floor laid flat holds water against the skirting until it finds the wall behind. Hollow tiles crack under a dropped weight and lift at the corners.
What to look at
- Water poured on the finished floor running to the trap
- A tap-test sweep of every wet-area floor
- Consistent joint width, and the spacers actually removed
How to check it yourself
Wet areas are laid to a fall toward the drain and the fall is checked with water, not with a spirit level alone — pour a bucket and watch where it goes. Bedding mortar is full under the tile; tap across the finished floor and listen for hollows.
Where this comes from: IS 15622 (pressed ceramic tiles) for the tile; NBC 2016 Part 9 for drainage falls (indian standard or building code)
