How to Use Mainland Aggregates Gravel Calculator

Designing and creating a pathway can transform your outdoor space, adding functionality and aesthetic appeal. One important aspect of pathway construction is determining the amount of gravel needed for the project. Calculating the required quantity of gravel ensures you purchase the right amount and minimizes waste. Mainland Aggregates has a useful tool the Gravel Calculator to help you calculate the correct amount of gravel you will need for you project.  

Measure the Pathway: Start by measuring the length and width of the pathway using a tape measure, as well as how long the pathway will be. Note down these measurements’ metric.  

Determine the Depth: Measure or decide on the desired depth of gravel for your pathway. A typical depth ranges from 50mm to 100mm, depending on the intended use and soil conditions. 

Calculate the Volume: To find the volume of gravel needed simply enter the measurements into the Gravel Calculator.  

Calculate Your Order: Once you have the approximate weight of gravel required the quantity of bulk bags can then be calculated. For example, 20mm Golden Flint Gravel is delivered in 850kg bulk bags.  

Compaction and Settling: Gravel can settle over time, so it's advisable to account for compaction and settling. It is recommended to add 10-15% to the calculated amount to compensate for this. It may also be prudent to secure the newly laid gravel with a Geotextile membrane.  

It's important to note that the Gravel Calculator provides an estimation and may vary depending on the type and density of the gravel being used. Consult with us at Mainland Aggregates to ensure accuracy and account for any specific factors related to your project.
