Deciding the correct amount of walkway base material is actually quite simple. For sidewalks and patios or any other light duty areas you will only need a 4 inch base of 3/4 inch quarry process or RCA beneath a 1 inch layer of concrete sand.To correctly figure out how much base material that you will need you will first need to know how each material is measured.e sure to add the thickness of the pavers that you will be laying to the depth that you dig. Also, remove an extra 8 inches of soil beyond the planned edge of your pavers. Once you have removed the soil you will now need to run the âsub-baseâ with a plate compactor overlapping each pass by 4 inches.
