I will be having a concrete foot path around the house and also concrete our Alfresco area. As my funds don't allow to get this done yet I was thinking of doing any digging out required, laying and compacting the crushed rock base. This should help with my mud problem for the time being.
So to work out if I need to dig out, how thick should the crushed rock be ?
and how thick should the concrete be on top of that ?
