1 ton of crushed rock will typically cover an area of roughly 25-35 square metres. The exact amount that can be covered will vary depending upon several factors, such as the size and type of the crushed rock, the depth of coverage you are looking to achieve, and the area you are working with.
Generally, you should plan for a coverage area of 50-60mm (2-2. 5 inches) for most types of crushed rock, but this can increase or decrease depending on the size of the particular crushed rock and the area being covered.

How do you calculate how much crushed rock I need?
Calculating how much crushed rock you need depends on several factors, such as the size and shape of the area you are filling, the type of rock you are using, and the depth you wish to fill the area.
To determine the amount of crushed rock you will need, first measure the length and width of the area to be filled in feet. Then, multiply the length by the width. This will tell you the square footage of the area you need to cover.
Next, decide on the depth you would like to cover the area with – a good general rule is that one cubic yard of crushed rock covers about 100 square feet with a depth of 3 inches. Now you must calculate the volume of rock you will need by multiplying the length by width by the desired depth in feet.
Finally, divide this number by 27 to convert the volume into cubic yards. To get the exact number of cubic yards you need, subtract any areas of the coverage you won’t need to worry about, such as areas under trees, driveways, sidewalks, or other obstacles.
When you are finished, you will have the exact amount of crushed rock needed to complete your project!.
How many tons of rock do I need per square foot?
The exact amount of rock you need per square foot can vary depending on your particular project. Generally speaking, it is recommended to use 3-8 inches of clean and washed rock for drainage systems, edging, patios, fire rings, landscape beds, pathways and gardens.
Depending on the size of the rock, this can range from 0. 25-1. 25 tons per square foot. For example, for a standard ¾ inch rock, you would need about 0. 5 tons per square foot. If you are using a 1.
5 inch rock, you would need approximately 1. 2-1. 3 tons per square foot. It is important to order the right amount of rock so that you do not run out before the job is complete. Additionally, keep in mind it is typically cheaper to purchase rock in bulk and it is always wise to get a second opinion from a professional before committing to a particular amount and type of rock.
What size gravel is for driveways?
The size of gravel used for driveways typically ranges between 3/8” and 3” in diameter. For best results, choose a gravel consisting of crushed rock, quartz, granite, or recycled asphalt. It should also have a course, angular shape to help promote stability and provide an attractive appearance.
Additionally, it should have a mix of sizes, including fine and coarse particles, so that the mixture can pack together and will not scatter or be displaced easily. If installing a gravel driveway, you should consider crushed stone along with gravel to help form a hard and durable surface.
Making sure the gravel is properly installed and layered is also important, because it provides better results when the pieces fit together like a puzzle.
How many square feet is a ton of natural stone?
It is impossible to know how many square feet a ton of natural stone will cover since it depends largely on the size and thickness of the stone. Generally, however, one ton of natural stone will cover approximately 80 to 100 square feet with a depth of 2 to 3 inches.
Additionally, it is important to note that the coverage can be significantly less for thicker natural stone.
How thick should a crushed rock driveway be?
The thickness of a crushed rock driveway depends on several factors and should be determined by an experienced professional. Generally speaking, it is recommended to install a minimum thickness of 4-6 inches of road base material, which is composed of native soils and/or crushed aggregate, and to add 1-2 inches of screening or 4-6 inches of a dense graded aggregate.
A professional should also consider the amount of traffic, type of traffic including the weight of vehicles, and whether the area will freeze and thaw. Additional considerations include water diversion and the total load that will be transferred to the structure including soil, gravel, paving materials, and vehicles.
It is important to properly prepare the subgrade, compacting and adding geotextiles and a drainage layer to further ensure the longevity and stability of the driveway.
What size is #2 gravel?
#2 gravel, also known as “processed gravel,” is a combination of stone and sand. The size of the gravel typically ranges from 1/4 inch to 1 inch in diameter, making it an ideal choice for a variety of projects including landscaping, pathways, and ground cover applications.
Unlike crushed stone, which is produced by breaking stones into small, uniform pieces, #2 gravel is created through the process of sifting and sorting stones and mixing them with sand. This process usually involves passing the stones and sand combination through a wire mesh screen or sieve, which helps to separate the stones from the sand and to break them down into smaller pieces.
Once the stones and sand have been sifted and sorted, the mixture is then screened to a specific size, with stones measuring from approximately 1/4 inch to 1 inch in diameter. The result is then referred to as #2 gravel, or “processed gravel”.
How much compacted gravel do I need?
The amount of compacted gravel you need depends on the size and type of project you are doing. If you are working on a driveway, for example, you will need to calculate the square footage. Generally, it is recommended to use 4–6 inches of gravel and to compact it to 2–3 inches.
Depending on the size of the area you are working with, you can calculate how much material you will need. To calculate the amount of compacted gravel, you need to multiply the square feet by the desired thickness.
For example, if you have a 10 by 10-foot area, you would need 100 square feet. If you are using 4 inches of compacted gravel, multiply 100 which is the square footage by 0. 33, which is 4 inches converted to feet, to get 33 cubic feet of gravel.
That is equivalent to 1. 5 cubic yards.
