Ememem is a French artist who "fixes" potholes and various elements of public spaces. I posted about him quite a while back, but he doesn't lack places to fix.
If he uses the right materials (ceramic, adhesive, etc.), prepares the surface correctly, plus a good technique, and everything according to the local weather, it should be fine for at least ten years. I just hope it's the right stuff because someone can slip on it and everything can end with jail and a lot of money to be paid for who knows what. π€·
for ememem-style pothole mosaics, use fragmented ceramics or porcelain tiles for durabilityβthey resist compression well on a solid base and last years outdoors. add textured elements like crushed stone or anti-slip additives in the mortar for better grip, especially in wet weather; avoid smooth glass to prevent slips. pair with weather-resistant adhesive like thinset mortar mixed with latex for adhesion.

There always is, you just have to pay attention. Last week I passed by a small coffee shop and saw the details for the first time, after way too many years.
