Surface to use in humid conditions
I currently live in the dry east of the country where high humidity is not a problem. However, I’ve bought a house in France and the winters can be twice as wet as where I am now. Part of the garden is a courtyard area currently covered in some sort of shingle that is so overgrown with moss and algae that it’s impossible to view properly. I would like to be able to put a sitting/dining area in the courtyard, and have been thinking of hard landscaping it. But I am worried that paving stones would have to be pressure cleaned all the time because of the algae. People who live in more humid areas of this country, what advice can you offer me? I’m open to any kind of surface (that is not plastic or concrete). It needs to be reasonably level for the table and chairs. Hoggin? Replacement gravel? What works well?
