Too few aggregates can lead to additional deliveries, which can waste time and money. Too many aggregates lead to wastage too. Are you wondering how much gravel or slate you will require for your project? To help you, we have developed a gravel calculator for you to use. How much gravel or slate do I need? All you need to know is the size of the area you wish to cover, what depth of gravel or slate you require, and your post-code. The size information helps calculate how much gravel or slate you will require, while your post-code helps us calculate a cost estimate based on delivery.
Try it yourself now. Note: This calculator is only intended as a rough guide to help you approximate the likely volume of gravel , slate or other aggregates needed for your project. Calculating an accurate estimate of how much gravel or aggregate you need for a driveway is simple with our gravel calculator. All you need to know is the desired length and width of the driveway, along with what gravel depth you need. You can get an estimate right now using the calculator above.
If you would like a very rough estimate, take a look at our table below. To calculate how much gravel you require for your garden, you must know the approximate area you are working with, and the desired depth. For gardens, this can be trickier as the shape may not be a simple square. Calculate the area of the excavation, multiplying the length and width together.
You can also type the area of the excavation directly into the gravel estimator if you choose to excavate a more sophisticated shape. We've got calculators to help you find the areas of many geometric figures like triangles or pentagons.
For even more examples, visit the 2d geometry section of our math calculators page. Determine the depth of the excavation. The volume of gravel required is equal to the volume of excavation. Our gravel calculator will display this value for you. Types of gravel We can differentiate various types of gravel on the basis of: Size — there are many sizes of gravel. We can find some with rock fragments 4 inches about 10 cm in diameter and others with a particle the size of your fingernail.
Of course, different sizes serve different purposes. Normally, we would like our gravel path to consist of 2 or 3 different layers of gravel. First, we can lay machine-crushed gravel of a larger size that will serve as a solid foundation for more aesthetic higher layers.
We can add sand or dirt to this basal layer of gravel. At higher levels we would like to have gravel of a smaller size that will fit into the holes between the stones of the foundation layer. Shape — we will talk about shape in terms of the topmost layer of our gravel path. We can go for pea gravel that consists of smooth, round, naturally-weathered stones. It will not only be pleasant for the feet of your children because of its smoothness but also attractive to the eyes of you and your neighbors.
However, pea gravel also has its downsides. It can shift under pressure, creating footprints or trails behind your car. The owner of a pea gravel path has to get used to raking and refilling gravel from time to time. The other option is to choose an angular type of gravel. Although not as comfortable to walk on if someone falls they might even get hurt! This is thanks to particular rocks locking into one another.
Examples of angular types of gravel are decomposed granite, lava rock, and quartzite. Color — this is an important attribute of landscape gravel, as it needs to fit your personal taste and the environment — the style in which your house and yard are designed.
Darker colors will retain more heat and raise the temperature of gravel so it will dry more easily. But watch out! It also might burn your feet on a sunny day! If you want your path to look natural, you should go for gray or light brown gravel. An interesting choice might be Jersey Shore gravel with its yellowish, golden-like color.
And, if you want to stun your neighborhood — marble chips will do the trick. They will sparkle in the sunlight, making sure that your yard will stand out from its surroundings! Gravel estimator - how to calculate landscape gravel quantity? First, we need to divide the pea gravel path into four rectangles: 1, 2, 3, and 4. Now, we have to measure the width and width of each sector: Sector 1 has the length of 10 yd and the width of 0. Sector 2: the area is equal to 4 yd multiplied by 0.
Sector 3: the area is equal to 4 yd multiplied by 2. Sector 4: the area is equal to 10 yd multiplied by 0. Again, the gravel calculator will do this math for you. In case the area you are calculating has an irregular shape, things get a bit more difficult, but in general what you would want to do is divide it in several regularly-shaped sections, calculate their volume and gravel requirements and then sum them up together.
The one-click copy function of our tool should come in handy. In case you end up with a large number of sections to sum, you might appreciate our summation calculator. Gravel is a naturally occurring material, consisting of water-born pieces of rock and is found in buried or current stream beds. The peas are usually rounded with smooth surfaces, while other properties depend on "parent rock".
You may also encounter "crushed gravel", which is simply larger gravel particles crushed to a smaller desired size. Gravel is usually sold with a guaranteed maximum particle size, e. This means that no side of any particle will be larger than the specified measurement, which is achieved through screening, usually using industrial automated screeners.
Note that a gravel's density depends on this, so make sure to consult the manufacturer's technical specifications for the estimated density which you should then input in our gravel calculator. Crushed stone is often used as a material for producing concrete. It is also used as a road base, and in some locations it is used for paving roads, for example Russia has over , km , mi of gravel roads. It is a great driveway base material, bike path base fill, paver patio sub base, walkways, and just general fill material.
Some types of gravel offer excellent drainage as water is able to percolate through the stones leaving your property or walkway clean and dry. Contrary to what you may think, there is more than one type of gravel, both by composition and size of the stones. Selecting the right size and style is crucial for the success of any construction project, as some are more versatile and have a different application than others.
For example, landscaping gravel would last longer than mulch or pine straw, making it great for outdoor spaces requiring a durable material, while construction gravel provides solid footing for construction and landscaping.
Different types of gravel have different densities and by knowing it you can get a more accurate estimate for the amount of gravel you need. It is further categorized in several types, listed in the table below [2] :.
For small projects, you can buy pea gravel in small bags, but for larger projects, you would need to buy by the cubic yard or by the ton cubic meter or tonne. Our tool allows you to enter price per ton or tonne to get a price estimate as well. This corresponds to gravel with average sized pebbles and is the number used in the calculator.
