Building a patio

[Grahamm]

If youre layin slabs of any description, my advice would be to lay them on a full bed of mortar with mortar joints, or youre likely to be plagued with billions of foccin ants every summer getting between the joints and nesting, and when they start to fly its like a black cloud.

Thanks for the suggestion, but there's going to be a narrow flower bed along the edge where it runs alongside the garden wall, so they'd just get through that anyway!

Also cement/ mortar adds another level of complexity which we'd prefer to avoid if at all possible.
