The amount of sand you use can make or break your paver installation, so it's best that you use no more than the recommended 1 inch. Here's why: A sand layer that is too thick can create waves in your patio during the installation. Pressing pavers into a thick sand bed may result in misalignment and a messy look.
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. Once your sand is in place, you'll use a 10'–12' strike board to “screed” the sand.
Paver sand holds the pavers in place and allows you to adjust them. The final paver sand depth needs to be 1 inch and you need to account for sand filtering into the paver base and into the joints between the pavers. Make your calculations using a sand depth of 2 inches or 0.1667 feet.
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.
Prepare Ground
Ensure you have a root and rubble free compatible sand sub-base of at least 50mm thick. The sub-base should be roughly levelled and damped down before tamping down firmly with a hand or mechanical compactor. Hand compaction is usually enough for most domestic applications when 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.
Dry laying allows porcelain pavers to be laid directly on grass and sand, but also on gravel, thanks to their reduced thickness of 20 millimeters that avoids the use of adhesives.
Set up the guides so that your pavers will be 3/8" (1 cm) above the finished level (this allows for your final compaction). Level the sand evenly by pulling a board along the pipes (see photo).
Durable and attractive, pavers make a great choice for outdoor flooring. Sustaining their beauty requires little work. However, since pavers are exposed to various elements such as rain and wind, the joint sand between pavers may get washed out overtime. Occasional washing can also cause the joint sand to corrode.
Once the silica joint sand has been activated by the urethane in our Ure Seal h2o brick paver sealant, the 4 grain silica sand will become extremely hard, comparable to the consistency of concrete.
A minimum of 24 hours drying time is required prior to allowing foot traffic and 48 hours for vehicular traffic on the paver surface. Dampening: Apply a gentle fine mist to the filled joints, flooding the faces of the pavers and allowing the water to run into the joints. Do not flood the sand onto paver surfaces.
Therefore, you need to dig a paver patio base depth of about 9 inches (22.86 cm) to accommodate any kind of paver. 5 inches (12.7 cm) of the hole will be filled with the base material for the base such sand or gravel.
Whilst it is technically possible to lay pavers on bare, unprepared ground, this practice is not recommended as the ground will shift over time, causing the pavers to develop a sunken look, or even crack.
What Happens If You Don't Put Gravel Under Pavers? Drainage can really make or break an area where pavers are installed. If you have a paver patio, for example, without gravel or an alternative drainage system in place, water can roll back on it, causing damaging erosion.
The paver bed is usually made of sand, 1/4″-10 crushed gravel, or synthetic material, and is the topmost paver support layer keeping pavers in place.
A GRAVEL BASE LAYER BEFORE SAND IS A MUST! Using sand alone to set pavers is not enough. The best and recommended paver base is 3/8-inch crushed gravel. The gravel provides a flexible base that absorbs ground tension to prevent frost heaves.
The traditional base for a paver patio is 4–6” of compacted gravel above your dirt. If you're installing a driveway or road intended for vehicular traffic, you'll need to double the thickness of your gravel layer.
Landscape Fabric Works Under Rocks and Pavers, Too
Laying down landscape fabric will help prevent unsightly weeds from popping up in between the rocks and pavers, and as you probably already know, these are a pain to get rid of.
To compact the pavers themselves without a plate compactor, you're going to use a rubber mallet. You will not use a hand tamper at this part. It is too rough, and it requires more strength than a paver requires. It can even damage the pavers, especially the ones with a more glossy finish or the most soft stone pavers.
You can choose to fill the cracks between pavers with a polymer sand. This filler, once wet with a hose, turns hard, almost like mortar. It will make it tougher for weeds to take root. Or, plan to seal the patio once it's complete.
What is Polymeric Sand? Polymeric sand is a material used to fill paver joints, the empty spaces found between each paver, tile or natural stone.
Take a garden hose, with the nozzle set to mist, and lightly spray it over the pavers, starting from the highest section and working your way down to the lowest. Not only does this harden the polymeric sand in the gaps between pavers, it also removes any remaining sand from the stone's surface.
To fix sunken pavers, follow the six-step process we've outlined below. We will have to pull up the paving stones, remove our bedding layer, add gravel, tamper the gravel, and put some new sand back in—then we can lay our pavers again.
