Revisions log for Answer #459

The 2 cm plates and size without glue are very, very critical of many people. I did a lot of googling and asking beforehand, and most said they had to be glued.

We too were very unsure and last year we laid 90x45x2 slabs in a gravel pad. There is a very narrow joint with inversion sand.

Underneath is tamped gravel and curbs set in concrete all around.

So far we are very happy, except for a few rookie mistakes (2 slabs are wobbly, the edge in the front is too high, so green cover forms there over the winter, and cleanup is somewhat difficult). But they can be fixed if we take the trouble.
