Does anyone know what this is? It's in a few other places too.
It wasn't there initially but has appeared over time. Dangerous for the house?

There is a slope from the house of 2-3cm/m.

Water splashing from above and running towards the ground, and if the tiles are possibly made of concrete, it can result in deposits on other surfaces that look like lime scale. Make sure the slope is not towards the house; all water should be directed away.
