We currently have a patio area that is covered with slate chippings on top of rough MOT type one stone, which didnt seem to have a good quantity of fine compactable material in it
We are now thinking of removing the chippings and having paving slabs laid
I am wondering how thick the sub base needs to be?, if the MOT type hardcore isnt that well compacted and is fairly lumpy (to put it midly) would i need to start again
Also are paving slabs best laid on motar or a sand base?
