To start figuring out how much road base you need for your project, you need first to determine the area you’re going to be covering. If the area you’re covering is rectangular, the calculations are quite straightforward: multiply the length by the width.
First measure the square footage of the project area. This is achieved by simply multiplying the width times the length. Next, multiply your square footage by .01235. This equation will give you the amount of stone that you will need for your base in cubic yards.
For sidewalks and patios or any other light duty areas you will only need a 4 inch base of 3/4 inch quarry process or RCA beneath a 1 inch layer of concrete sand. To correctly figure out how much base material that you will need you will first need to know how each material is measured.
Deciding the correct amount of walkway base material is actually quite simple. For sidewalks and patios or any other light duty areas you will only need a 4 inch base of 3/4 inch quarry process or RCA beneath a 1 inch layer of concrete sand.
To determine how many paver stones you need:Multiply the length and width (in feet) of the area you're paving.Multiply the length and width (in inches) of your bricks or paving stones.Divide the brick or paver's surface area by 144 to convert to square feet.Divide the total paving area by the paver's surface area.More items...•
Multiply the length (L), in feet, by the width (W), in feet, by the height (H), in feet, and divide by 27. This number is how many cubic yards of crushed stone you need.
Accurately Measure Required Base Material 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.
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.
approximately 100 square feetA ton of gravel will cover approximately 100 square feet, 2 inches deep.
Measure the length and width in metres of the area you wish to fill with a sub base aggregate e.g. 20m x 10m. Multiply the length and width to find the area in square metres. Multiply by the depth e.g. 150mm. Multiply by 2 to get the tonnage required.
For a strong foundation, your paving may need road base. If you are paving a driveway or on an unstable site, it is recommended that you consult a suitably qualified engineer. Generally, road base is layed to a total depth of 100 to 150mm (10-15cm) around the entire area.
The depth at which you will need your base will depend on where you are laying your paving and whether you want this paving raised or at ground level. The Typical measurements are a depth of 150mm. This includes a 75mm sub base, 50mm of a mortar mix or sharp sand and then the paving on top of this.
So, assuming your paver size is 12″ x 12″, multiply 12×12 and then divide 144 by the answer. You'll find that 144 ÷ (12×12) = 1.0. That means you need one paver per square foot, which makes sense since a 12″ x 12″ paver is 1 square foot.
Generally, a typical 50 lb bag of sand yields 0.5 cubic feet, which will cover approximately 3 square feet area for standard 2 inch depth, 6 square feet at 1 inch deep, 2 square feet at 3 inches deep, or 1.5 square feet at 4 inches deep.

When filling small gaps, a 50lb bag of polymeric sand will usually cover 75-100 ft2. When filling wide gaps of 1/4″ to 3/8″ a 50lb bag will usually cover 30-60 ft2. Wider gaps, for example with a flagstone patio, will require even more sand to fill.

How much does brick paver installation cost? Most homeowners pay between $8 and $25 for installing pavers. Excluding equipment, labor, cement, and other fees, here’s a quick rundown of the costs of each.
For sidewalks and patios or any other light duty areas you will only need a 4 inch base of 3/4 inch quarry process or RCA beneath a 1 inch layer of concrete sand.
Crushed stone, which is what is recommended as a base material for a paver base is measured in cubic yards. First measure the square footage of the project area. This is achieved by simply multiplying the width times the length. Next, multiply your square footage by .01235.
To determine how many paver stones you need: Multiply the length and width (in feet) of the area you’re paving. Multiply the length and width (in inches) of your bricks or paving stones. Divide the brick or paver’s surface area by 144 to convert to square feet.
Traditional paver stones come in three typical sizes. Small stones are usually 0.2 square feet per stone, mediums are 1 square foot per stone and large ones are 1.71 square feet per stone. Some types, like Flagstone, come in uneven shapes. That means you have to make sure your design is well planned and that you have enough paver stones in case there are any mistakes.
To start figuring out how much road base you need for your project, you need first to determine the area you’re going to be covering. If the area you’re covering is rectangular, the calculations are quite straightforward: multiply the length by the width. For irregularly shaped areas, divide it into regular shapes such as triangles, rectangles, ...
Once you have your cubic yardage and the density of the material you’re using, it’s time to put it together. Multiply the two figures together, again maintaining awareness of your units to get an accurate result. If you’re using cubic yards, have the density measured in pounds per cubic yard, so the units match up well, and you have fewer conversions to do. This calculation should give you the number of pounds of rock base you need. Once you have that number, divide it by 2000. The result is the number of tons of road base you need for your project. Consider adding a little extra to your total to make sure you have enough in case you accidentally waste some product.
For irregularly shaped areas, divide it into regular shapes such as triangles, rectangles, and circles. Find the area of those shapes with their respective formulas and then add them together. The combined area will give you the square footage of the area you’ll be covering.
If you don’t have enough, you’ll have to stop and wait to finish the job until you resupply. If you have too much, you’ve wasted money and material. While you may be able to use the extra material for a future job, it’s still better to avoid that when you can. So how do you figure out how much road base you need to avoid these problems?
In-place densities for most compacted granular or crushed base courses should be in the range of 3510 to 3780 lbs/yd 3 (2080 to 2250 kg/m 3 ).
"road base" usually comes in various types. They are mix of very fine (dust-like), medium (sand-to pebbles), and coarse (up to about 2") materials.
To determine how many paver stones you need: Multiply the length and width (in feet) of the area you’re paving. Multiply the length and width (in inches) of your bricks or paving stones. Divide the brick or paver’s surface area by 144 to convert to square feet.
