Hi All,
I'm planning to lay a 30sqm (~8mx4m) area and a 10sqm path using sandstone pavers at my new house.
The sandstone is 400x400 naturally split so they vary in thickness from 15 to 20mm.
I am planning to lay down about 5cm of Road base and compact it, then lay down 5 cm of concrete over the area.
Then I will mortar down the pavers.
My questions are these, are the thickness of road base and concrete okay for a patio area?
Do I need to have expansion joints?
if I do need expansion joints are they sawed in after the pavers go down? Whats the process?
Thanks
Luke
