Is it ok to put paving slabs directly onto bare soil in my back garden? I don't want to do the proper patio thing. I just want some even area that is not muddy to have summer picnics on.
StephenW
What happens is when it rains the soil underneath turns to mud and comes up through the joints when you walk on the slabs. This then leaves a hollow under the slab which means it wobbles more and squirts more mud up through the joint. When it dries the slab will be loose and will not be level.

How to make a slab smoother?
