If you're planning a backyard makeover, you're most likely trying to figure out how many square feet does a ton of rock cover before you mind down to the local landscaping supply backyard. It's one of those questions that seems like this should have a simple, one-size-fits-all answer, but in actuality, there are a few variables that can replace the mathematics.
The short answer—the 1 most contractors will certainly give you off the top of their heads—is that one ton of rock typically covers about 100 square feet at a level of 2 inches.
But before a person pull out your credit card plus order five tons for your driveway, we should probably speak about why the number of isn't set within stone. With respect to the size of the stones you choose and how deep you want to pile them, that coverage could reduce down to 50 square feet or even extend to a hundred and fifty.
The basic rule of thumb for rock coverage
When you're browsing the particular middle of your yard with a tape measure, you will need a starting point. Most landscaping professionals agree that regarding standard decorative small or crushed rock (roughly 1 inch in size), a ton is heading to give a person that 100-square-foot protection if you're growing it about two inches thick.
Two inches is normally the "sweet spot" for most projects. It's heavy enough to cover the dirt or weed fabric underneath, yet not so strong that you're too much water in rocks or making it impossible to walk via. If you're performing a driveway, you might want this a bit deeper, maybe three ins, which obviously means that same ton of rock won't proceed nearly as far.
Why the size of the rock changes everything
It's easy to forget that "rock" covers everything through tiny pea pea gravel to those huge, chunky river gemstones. The physical dimension of the individual stones plays a huge role in determining how many square feet a ton will cover.
Believe about it in this way: smaller rocks, such as pea gravel, package together much more tightly. There isn't a lot of "empty" air area between the stones. Because they're so dense, they cover less surface region per ton than larger, more irregularly shaped rocks might.
Upon the flip side, if you're using large 3-inch water rocks, they don't settle into every other just as much. A person get more "void space" between the particular stones. While this might make this feel like you're getting more insurance coverage, you often possess to pile all of them deeper in order to make sure you can't see the ground via the gaps. Therefore, while the math changes, the "ton equals 100 square feet" rule generally averages out to be a quite safe bet intended for most medium-sized landscaping design stones.
The particular depth factor: How deep do you really require to go?
This is how most individuals get tripped up. When you ask how many square feet does a ton of rock cover, you possess to decide upon your depth first.
- 1 inch heavy: In the event that you're just "freshening up" an present bed of stones, you might just needs an inch. In this instance, a ton can cover roughly 200 square feet .
- 2 inches deep: This is the standard for new pathways and garden bedrooms. A ton addresses about 100 square feet .
- 3 inches strong: This is recommended regarding driveways or areas where you want in order to suppress weeds without using any plastic underlayment. At this depth, a ton only covers regarding 66 square feet .
- 4 inches deep: If you're building a foundation for a lost or a quite heavy-duty driveway, you're taking a look at about 50 square feet per ton.
In case you don't account for depth, you'll almost certainly finish up short. It's always better to possess a few buckets of rock left over in order to have got a giant bald spot within the corner of your new patio.
Different kinds of rock have various densities
Not all rocks are made equal when it comes to pounds. A ton is definitely 2, 000 pounds, but 2, 000 pounds of 1 material might get up more bodily space than 2, 000 pounds of another.
Regarding instance, lava rock is extremely porous and light-weight. Because it's complete of tiny surroundings bubbles, a ton of lava rock will cover a much larger area than a ton of heavy granitic or river rock. You might obtain double the insurance coverage with lava rock simply because it's less dense.
On the some other end of the particular spectrum, something like crushed limestone or granite is very heavy. These rocks are solid and dense, meaning they won't cover quite just as much ground per ton. When you're in the supply yard, it's worth asking them if the specific rock you including is particularly large or light, since that can throw your calculations away by 10% or 20%.
How to accomplish the math for your project
I am aware, nobody loves doing math on the weekend, yet it's the only method in order to make sure you don't overspend. Right here is the simplest way to figure out there how much rock you need:
- Measure the area: Discover the square video of the area you want to cover (Length back button Width). If it's a circle, properly, God speed—or simply use a chain to get the diameter plus use an online loan calculator.
- Determine on depth: Convert your own desired depth directly into feet. For example, 2 inches will be 0. 16 feet (2 divided by 12).
- Calculate cubic feet: Multiply your square video clip by that decimal depth. (e. gary the gadget guy., 100 sq ft x 0. 16 = 16 cu feet).
- Convert to tons: Most standard landscaping rock weighs about two, 500 to several, 000 pounds for each cubic yard (which is 27 cubic feet). This indicates a single ton is roughly 18 to 20 cubic feet.
If that feels like too very much work, just keep in mind the 100-square-foot rule at 2 inches deep and adjust slightly centered on whether your own rock is especially chunky or especially light.
Common mistakes to prevent when ordering
One mistake I actually see all the particular time is people forgetting that rock settles. When the shipping truck dumps that pile within your driveway, it seems like a mountain. But as soon as you spread it out and walk on it a bit—or once it rains—the stones shift and settle into the nooks and crannies. This particular "compaction" makes it appear like you didn't buy enough.
Another thing in order to keep in thoughts could be the "fluff aspect. " When rock is crushed plus moved, it offers more air in it. After a few weeks of sitting in your own yard, it'll package down. I usually suggest ordering about 10% even more than your math says you need. Getting a little extra tucked away behind the garage will be a lifesaver when you notice a thin spot 6 months from now.
Also, don't forget about the border! If you're building an elevated bed or using a heavy plastic material edging, that takes up a bit of volume, as well. However, most people find that their measurements aren't perfectly exact anyway, so the particular 10% buffer generally covers these small discrepancies.
Purchasing in bulk versus. buying bags
If you only require to cover a tiny 10-square-foot area, you're better away from buying bags from a big-box store. But if you're wondering how many square feet does a ton of rock cover, you're most likely looking at a larger project.
Buying by the particular ton (bulk) will be almost always considerably cheaper than purchasing by the handbag. A ton of rock at a landscaping yard might cost anywhere through $30 to $150 depending on the type of stone. In case you tried to buy that same amount in 40-pound bags at a home improvement store, you'd be starting 50 bags and paying three periods the price.
The catch along with bulk is the particular delivery fee. Most places charge a flat rate in order to drop a stack in your entrance. If you only require one ton, the particular delivery fee might cost just as much as the rock itself. In the event that you need three or four plenty, bulk is a no-brainer.
Conclusions on your rock project
At the end of the day, landscaping design isn't an exact science. You're dealing with natural components that vary in shape, weight, and size. While the "100 square feet for each ton" guideline is definitely the industry standard, your specific backyard might behave a little differently.
Take your period with the dimensions, consider how deep you really require the coverage to be, and don't be afraid in order to ask the people on the rock yard for opinion. They see these materials every single day and may usually inform you exactly how a particular batch of Tennessee River Rock or crushed granite will be going to distribute.
As soon as you get that will number right, just about all that's left could be the "fun" part—shoveling it all into place. Good luck with the project!
