First let me say what a super site this is. Factual, to the point and full of useful information and links.
I have been considering using some 600x600 slate slabs in my garden. My idea is to lay a chess board pattern and use pea gravel in the non slate squares. The plan is to use a 10:1 grit sand/cement mix 50mm deep across the full 20m² area, and then lay the slates in a chess board pattern and then fill the empty 600x600 squares with the pea gravel when the mix has gone off fully.
Most of the area will be used only occasionally and one area, down the side of the house, as a path once or twice a week. Very very light use.
The question is this: Will the semi dry mix be OK for this and perhaps more importantly, because the gravel squares will fill with rain, I will make some holes in the bedding of those squares for drainage, but will the slate slabs stay fixed in place or will water at the base edges of the slabs cause a problem? I can leave a 10mm space between corners of the slabs and the rain can run off the bedding to one edge. But will that undermine the slabs?
Thanks
