Is terrace slab thickness under 2 cm also okay?

Small animal litter. You can then sweep it up and dispose of it. : I am surprised that as a wood floor lover you don’t want this on the terrace as well.

My goodness, you know my innermost self :eek: :eek: Terrace wood is already reserved, larch about 40mm. Unfortunately, the start of construction depends on the current frost. First Christmas, then post-Christmas period and now frost........ Then it will soon be Christmas again anyway. We used to have what I consider nice concrete slabs, but not laid in gravel for the reasons mentioned.
