Evening all.

As the thread title suggests, I am planning to lay a mix of patios and paths in the garden of my SB.  As part of achieving the necessary levels for the house itself, the courtyard garden was excavated down to subsoil level, which in my case means thick clay. Not sure if the photo shows it clearly, but the clay is fully exposed throughout, there isn't a pinch of soil to be found anywhere!

 

I plan to compact about 100mm of MOT type 1 and 2 subbase, then use normal 5:1 mix on top, then lay slabs having back-buttered them with adhesive. 

 

In other words, I'll just do the normal thing.

 

My question is, should I not be doing something else, too? Is the normal method sufficient given the ground conditions?

The paving may still shift about as the ground swells and shrinks. Not much you can do on a domestic patio.
