When it comes to calculating the amount of pea gravel you will need for a specific area, it is important to know the coverage rate. In this case, 1 ton of pea gravel covers 100 square feet, 2 inches deep. So, to determine how much pea gravel you will need for 200 square feet, we can follow these steps:
1. Calculate the depth: Since the coverage rate is given for a depth of 2 inches, we need to determine how much pea gravel we need for a different depth. Let’s say we want a depth of 1 inch instead. To do this, we divide the desired depth (1 inch) by the coverage rate depth (2 inches): 1/2 = 0.5.
2. Adjust the coverage rate: Now that we have the adjustment factor of 0.5, we can multiply it by the coverage rate to determine the coverage rate for our desired depth. 0.5 x 100 = 50. This means that 1 ton of pea gravel will cover 50 square feet at a depth of 1 inch.
3. Calculate the required amount: To find out how many tons of pea gravel we need for 200 square feet at a depth of 1 inch, we divide the area by the adjusted coverage rate: 200/50 = 4.
Therefore, for 200 square feet at a depth of 1 inch, you will need approximately 4 tons of pea gravel.
It is important to note that this calculation assumes a uniform depth throughout the entire area. If you have varying depths or slopes, you may need to adjust the calculation accordingly or seek professional advice. Additionally, it is always a good idea to order slightly more pea gravel than you think you will need to account for any irregularities or loss during installation.
In my personal experience, I had a customer who wanted to create a small pathway in their backyard using pea gravel. The area they wanted to cover was approximately 150 square feet. After discussing their desired depth and considering the coverage rate, we determined that they would need around 3 tons of pea gravel. However, to be safe, we ordered an extra half ton to ensure we had enough to complete the project without any shortage. It turned out to be a wise decision, as we encountered some uneven spots that required a bit more gravel to level out.
