Hello!
We have a rooftop terrace that is supposed to be tiled. The construction is (from top to bottom)
- tiles
- concrete, about 50 mm
- waterproofing, bitumen
- insulation
- poured flooring
Unfortunately, the builder has installed the tiles incorrectly. They did not apply the tiles with full adhesive coverage underneath. The voids that occur under the tiles can then fill with water, which in turn can lead to frost heaving.
This cannot be fixed afterwards. The only way to correct the mistake is to redo all the tiling. Now, I fear that the builder cannot manage this financially. The question is, what is my least bad option?
- Negotiate with the builder about me paying part of the cost to redo the tiling
- Live with the mistake and let the builder come back to repair any tiles that may come loose.
How big is the risk of frost heaving?
Best regards, N

If the builder cannot manage financially, there is a high risk that they will not be around to fix the errors when they appear...
I am fully aware that the builder may not be around in the future. But if the risk of frost damage is small, it might not be very costly to address. Alternatively, if the risk is high, over time you might end up replacing practically all the tiles, and then it might be cheaper to negotiate with the builder to redo everything now. This reasoning is the background to my question about the risk of frost damage.
So do you have any issues or do you think you will have issues? How do you know it is incorrectly installed?
The risk of frost heaving can probably only be answered by the person who laid the tiles because we know nothing.
It's hard to make a complaint before any fault shows.

If it is not done according to the manufacturer's assembly instructions, you can file a complaint. Like if you lay roofing felt incorrectly, but it hasn't started leaking yet.
