This can be done by measuring the length in meters and the width in meters. Once you have these 2 lengths, you then need to multiply them by each other. This will give you your approximate square area! You can do this with just a simple tape measure! Once you have all this information, you can then use our calculator on the side of most pages, just select the category of product e.
When you need to work out the amount of mulch you need for a certain area, you apply a similar principle by working out the amount of meters squared that you have. With mulches, 1 cubic meter will cover approximately 13 m2 70mm thick. So lets say you have 27m2 of area and want it covered at the recommended coverage of 70mm, you would need to purchase 2 cubic meters. There are 54 bags of stone or soil per 1 cubic yard. There are 27 1 cubic foot bags or 18 1. A bag of hardwood or cedar bark contains about 1 cubic foot of material, enough to cover about 4 square feet at 3" deep.
If you have large areas you probably need bulk. A less expensive alternative to buying in bags is to bring in and fill up your own containers with bulk materials. If you are dressing up a small area maybe bags are best if you do not have a way to haul bulk material. Mulch purchased by the bag is about 2 or 3 times more costly than bulk.
Stone purchased by the bag is about 3 or 4 times more costly than bulk. Soil purchased by the bag is about 4 or 5 times more costly than bulk. Tips for moving bulk material When shoveling heavy materials, using more small shovelfuls is easier on your body than using fewer but larger shovelfuls.
To find how much river rock you need, here are the steps to follow:. You are at the right place to find how much area or square footage a certain volume or weight of river rock can cover. You first have to enter the volume or weight of the available river rock you have , whichever value is known for this requirement.
Then input your desired river rock depth. You will then instantly see the area coverage of your river rock. Play around with the calculator to explore which variables you can work out by filling in your known fields and leaving a particular variable empty. At the very bottom, you will see the river rock cost calculator feature wherein you can enter the cost of river rock per unit volume or per unit mass to find the total cost of your selected river rock.
Now that we know how to use our calculator, either as a river rock coverage calculator or as a river rock cost calculator, wouldn't it be nice to also know how to calculate river rock's volume or weight on your own?
All you have to do is find the volume that you want to fill with river rock by multiplying its dimensions together while considering the percentage of waste you might have, as shown in the equation below:.
After calculating the needed volume of river rock, multiplying its value by the density of this river rock will give you the corresponding weight of your river rock, like in this equation:. You can check your preferred river rock's density value in the different types of river rock section of this text.
Let's say we want to make a 7. If you need the volume in cubic feet or cubic yards , you can use our volume converter for the conversion. Nevertheless, when using our river rock calculator, you can easily change its units by just clicking or tapping on its units and selecting the unit you want.
Going back to the computations, to know how heavy this volume of pea gravel is, we evaluate its weight using the equation below:. We now know we need more than 1, kg of pea gravel for our walkway project from our calculation above. Due to their smooth texture and round shapes, we typically see them used as pavement for barefoot pathways in gardens , around swimming pools , and even in shower room floorings. When combined with other underground structures like perforated drainage pipes and other subgrade rock layers, they can also prevent water puddling and soil erosion.
You can check your local gardening supplies or hardware store for river rocks in your area. For small quantities, you can buy them in bags of various sizes. These suppliers may offer you a truckload of river rocks for larger projects, depending on their availability. You can use river rocks to pave your pathways or to surround your plants to protect the soil from erosion or from pets that like digging soil.
Use light-colored river rocks for a cooler garden as they tend to reflect more sunlight than the dark-colored ones that absorb heat more. Typically, rounder rocks tend to cost more than irregularly-shaped rocks. Embed Share via. Table of contents: What are river rocks? How much river rock do you need?
