The guidelines are 4 to 6 inches for pedestrian walkways and 8 to 12 inches for driveways. Local soil conditions also impact depth needs. Generally, clay bases need to be dug deeper to facilitate drainage.
What is the maximum depth of sand under pavers?
Excavate the area to be paved to the depth of the paver plus 100mm for the compacted road base and 50mm for the compacted bedding sand (i.e. 150mm in total). Ensure that the base is gently sloped away from any nearby buildings allowing for a fall of 20mm per metre.
Do I need both paver base and leveling sand?
Once the paver base is laid and compacted, a layer of paver sand is added on top. This sand assists in leveling and offers a soft, flexible layer to place and adjust the pavers. After laying the pavers, additional sand is often swept into the gaps between them to lock them in place and prevent shifting.
Can you have too much sand under pavers?
Pavers that shift out of place can be caused be a number of things. One very common cause is a base that is not deep enough. A contractor can save a lot on materials by skimping the base, but it will compromise the structure of the pavement. Too much sand in the base can also cause pavers to shift or heave.
Is 2 inches of sand too much for pavers?
Pro Tip: It's very important that you lay no more than 1” of bedding sand. Any more will promote settling or wobbling—two things you don't want pavers to do.

Secondly, the sand allows water to drain out under the pavers. Otherwise, you may have standing water on the soil which will turn it to mud and the mud will ooze up between the pavers. The pavers will also tend to sink into the soft mud in places where people walk, especially if you have clay soil.
Do you compact sand before laying pavers?
ANSWER: Yes, hand tamp the sand and use a straight edge (or side of 2 x 4 board), from high end of slope to low end, to make sure you still do not have any low spots.

To achieve a firm base from the beginning, you need to make sure you have the correct depth of sand under pavers. We recommend allowing for a depth of at least 30mm loose sand.
