Once the patio has been laid out, use a mattock and shovel to dig out an area equal to the size of the patio and about 5-1/2 inches deep. If you are removing turf to make room for a patio, use excavated healthy turf to patch other areas of the lawn or to create a new area of lawn.
Calculate how deep to excavate by adding the depth of the gravel base, sand bedding and pavers. You'll need 4 inches of base for foot traffic, 6 inches if a lawn tractor will go over it and 12 inches for a driveway or surface vehicles will park on. The sand layer should be 1 inch thick.
