Multiply the square footage of the project area by 0.01235. The result is the amount of crushed rocks you’ll need in cubic yards. This will give you a 4-inch crushed rock base, which is the standard depth for a base when installing pavers.
How many inches of paver base do I need?
What depth of base materials is necessary? There is no absolute rule to determine how required depth, however recommendations vary by use. The guidelines are 4 to 6 inches for pedestrian walkways and 8 to 12 inches for driveways.
How do you calculate sand base for pavers?
The recommended depth of sand for laying pavers is 1 inch. As one inch is 1/12 of a foot, divide the surface area, in square feet, by 12 to find the cubic feet of sand required. For example, a 60-square-foot patio requires 5 cubic feet of sand because 60/12 = 5.
How many bags of gravel do I need for paver base?
Normally you want a base layer of gravel about 4-inches deep. Four inches is one-third of a foot, so multiply the square footage by one-third to find the cubic feet of gravel you need. For a 120-square foot patio that works out to 40-cubic feet of gravel.
How do I calculate my patio base?
How to Find Cubic Yards of Base Material Measure the length and width of the patio in inches. Multiply the length and width to find the area in square inches. Multiply the area by the gravel depth in inches to find the volume in cubic inches. Divide gravel cubic inches by 46,656 to find the amount of gravel in cubic yards.
How thick should sand be under pavers?
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.
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 put too much sand under pavers?
Excess sand slowly fills the joints and spills out of the edges and across paver surfaces. Even with edge restraints supporting the perimeter, sand eventually erodes out of the joints and causes widespread chipping and paver misalignment.
Can you lay pavers on just sand?
In other words, compacted sand can provide a sufficient base for a paver patio that’s just going to have you walking across it. You need to be able to place the pavers carefully so they drop onto the final layer of sand as flat as possible.

How many paver base panels do I need?
Measure the width and length and figure out how much material you’ll need. Divide the square footage of your patio by the square-foot coverage of each panel to determine the number of panels you’ll need. Add about 20 percent if your patio is an irregular shape.
Is paver base better than gravel?
The only significant difference between gravel and paver base, is that the sharper edges of paver base mean it can lock together more effectively than gravel when packed down under the sand and pavers. However, this does not negate the use of gravel if you tamp it down well enough.
How much does 1 yard of paver base weigh?
Approximate Weight per cubic yard (loose): 2400 lbs (1.2 tons).
How much base do I need for paver patio?
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 base be?
Site Preparation. The recommended depth you’ll want to dig to is about 150mm or 6 inches from the finished patio level. You can use a tape measure to check your depth is correct and once you’re happy you can compact the soil using a Vibrating Plate compactor, also known as a Wacker Plate.
How do you calculate blocks of pavers?
=[ total parking area × no. of paver blocks per sq ft.] = [360 sq ft. × 2.9 nos./ sq ft.]Jun 18, 2021.
Do you tamp sand before laying pavers?
Not compacting the base Before laying bedding sand or pavers, your gravel base needs to be flat and firm, without any bellies or rises of more than 1/8″.

Can you lay pavers directly on dirt?
Typically, it is not recommended to directly lay down pavers over dirt. For pavers to look and perform well in a permanent installation setting, the ground/dirt floor must be excavated, leveled, and hard compacted.
