How much sand do you put under pavers?
Plan on spreading about 1 inch of sand beneath the pavers, says Western Interlock. You’ll also use it to fill the gaps between them. The sand should be spread over a 4- to 12-inch layer of crushed stone, which has been tamped into place.
Can I put 2 inches of sand under pavers?
A 1-inch layer of level sand allows pavers to sink slightly into the bedding to hold them firmly in place. If the sand layer is too thick — 2 inches, for example — the compactor’s vibration causes the pavers to sink unevenly as the machine travels across the surface.
How much sand do I need for a patio base?
The pavers lie on a 5 1/2 -inch bed of sand and gravel. The bottom 4 inches is gravel to provide drainage. The top 1 1/2 inches is bedding sand that helps hold the pavers in place once they’re compacted into it. Finer sand, sprinkled between the pavers, keeps them from shifting.

How do I calculate how much sand I need?
To determine how much sand, topsoil or stone you need to fill an area: Measure number of square feet in the area. # of square feet x depth in feet = # of cubic feet. # of cubic feet /divided by 27 = # of cubic yards. # of cubic yards x (unit weight in pounds / 2000) = # of tons needed.
Can you install pavers without gravel?
You don’t have to lay gravel before pavers, but doing so can be beneficial to your project.
Can you lay pavers without gravel?

Does sand need to be compacted?
Working on and compacting granular soils such as sands and gravels are difficult tasks. Due to the composition of sand and gravel, water can enter or leave the voids in them with relative ease. This material must be compacted to provide the required strength.
Do you compact sand before laying block paving?
Apply a 50mm layer of damp sharp sand – it should be moist enough to compact, which you’ll be able to test by creating a ball of sand with your hand. If it doesn’t fall apart, it’s suitable to use. Once applied, use a vibrating plate compactor to compact it down and screed it.
How many inches of gravel do you need for pavers?
You’ll be using 4 inches of gravel, which is 1/3 of a yard, for a paver base. To figure out how many cubic feet of gravel you will need, multiply your square footage by 1/3. In this example, you’d need about 20 cubic feet of gravel, or 3/4 cubic yards. You may want more in case you spill some.
How deep should a patio sub base be?
Dig a depth of around 150mm across the whole area, making sure the soil is evenly compacted. Then tip in the sub-base, raking it into a consistent depth of 100mm. Make sure it’s smooth, flat and firm.
What is a good base for pavers?
Roughly crushed stone makes a good base for pavers that will be used more regularly. A base of 4 to 6 inches of well-compacted stone pieces provides a sturdy and stable foundation for nearly any type of paver installation, notes Concrete Construction, an industry website.
