![]() For paths, you would need the gravel layer to be thick enough to prevent weeds from growing in it if there will not be a weed barrier. Calculating concrete weight and dimensions can help you determine how much gravel you will need as a base. For example, you might have a layer of gravel as a base for concrete, with the depth of the gravel being dependent on the thickness of the concrete slab. The minimum gravel depth required depends on its intended use. Pea Gravel Cost = 22.8 tons x $45 per ton SInce you need 22.8 tons of pea gravel, it would cost about $1,026 for the gravel alone. Since this is a large project, let's say that you are buying bulk pea gravel at $45 per ton. It’s cheaper to buy bulk gravel compared to buying bagged gravel. The cost of gravel can vary depending on your location, the amount of gravel you are buying, and the season. Pea Gravel Weight = 480 cubic feet x (95 lbs per cubic feet) With a volume of 480 cubic feet, the weight would be about 45,600 lbs. Let’s say that we want to use pea gravel for our driveway. Gravel Weight = Volume (ft 3) x Density (lbs/(ft 3) Pea gravel has a density of 95 lbs per cubic feet, while crushed limestone can have a density as high as 140 lbs per cubic feet. For example, the density of gravel is about 105 lbs per cubic feet. Different materials will have different densities. This is how heavy the gravel is for a certain volume. To find the weight of the gravel, you will need to know the gravel’s density. Other common quotes for gravel can be by the yard or by the truckload, which is why this page allows you to calculate yards of gravel.

Volume of Gravel = 480 square feet x 1 foot A gravel driveway might have a thickness of 12 inches to 18 inches.įrom our driveway example, let’s say that the gravel will be 12 inches deep, or 1 foot deep, and covers an area of 480 square feet. For high-traffic uses with larger loads, you will need a thicker gravel layer. A common depth is 4 inches for gravel paths. The depth to be used is how deep you want the gravel to be. Once you know the surface area to be covered, you can easily find the volume of gravel needed by multiplying area by depth. Using the formula for the area of a rectangle, the area is 480 square feet.įor more complex and irregular shapes, you can use a square footage calculator to find the area. The dimensions for this driveway is 24 feet by 20 feet. Circular areas can be found by the formula πr 2, where r is the radius and pi (π) is roughly 3.14.įor example, let’s say that you want to build a two-car gravel driveway. For rectangular areas, such as driveways or straight paths, you can find the surface area by multiplying the length of the area by the width. You will need to know the surface area of the project in order to calculate the volume of gravel needed. Find the area to be covered with gravelĪrea is the space that the gravel will cover.To use this page to calculate pea gravel and other gravel types, you can follow these calculation steps: You can quickly determine “how much gravel do I need” by using a gravel calculator. Based on the type of material that you want to use, such as pea gravel, river rock, crushed limestone, or sand, the weight and estimated cost of gravel is also calculated. Once you know the dimensions of the area that you want to cover, the gravel calculator gives you a certain volume of gravel that you would need. Gravel can also be used to make paths, such as through your backyard, or it can be used for gravel driveways. Gravel gardens are low-maintenance and can be a great drought-tolerant landscaping idea. For example, you may want to calculate the amount of gravel needed to cover a garden. The calculation is based on the dimensions of the area, including depth, that will be filled in with gravel.
