How Many Bags of Pea Gravel for Fire Pit Area?
Creating a cozy and inviting fire pit area in your backyard is a perfect way to enjoy the outdoors and create lasting memories with loved ones. Pea gravel is a popular choice for fire pit areas due to its durability, affordability, and aesthetic appeal. But how many bags of pea gravel do you need to cover your fire pit area?
Determining the Amount of Pea Gravel
The amount of pea gravel you need depends on the size and depth of your fire pit area. Here’s a step-by-step guide to help you determine the quantity:
1. Measure the Area’s Dimensions:
Using a tape measure, determine the length, width, and depth of the fire pit area.
2. Calculate the Volume of the Area:
Multiply the length, width, and depth to find the volume of the area in cubic feet.
3. Determine the Coverage of Pea Gravel:
Pea gravel typically comes in bags with a specified coverage area per bag, such as 0.5 cubic feet per bag.
4. Divide the Volume by the Coverage:
Divide the volume of the fire pit area by the coverage area of one bag of pea gravel to get the number of bags needed.
Example:
Let’s say your fire pit area measures 5 feet long, 3 feet wide, and 4 inches deep.
- Volume = 5 ft x 3 ft x (4 in / 12 in/ft) = 5 ft x 3 ft x 0.333 ft = 1.665 cubic feet
- If the pea gravel coverage is 0.5 cubic feet per bag:
- Number of Bags = 1.665 cubic feet / 0.5 cubic feet/bag = 3.33 bags
Additional Considerations:
- Size of the Fire Pit: The larger the fire pit, the more pea gravel you will need.
- Depth of the Pea Gravel: The deeper the pea gravel, the more bags you will require.
- Slope of the Area: If the fire pit area is on a slope, you may need more pea gravel to ensure proper drainage.
- Buffer Zone: Consider adding a 1- to 2-foot buffer zone around the fire pit for safety and aesthetics. This will require additional pea gravel.
Tips for Purchasing and Using Pea Gravel:
- Choose pea gravel that is specifically designed for fire pit areas.
- Inspect the pea gravel for sharp edges or debris before purchasing.
- Spread the pea gravel evenly over the fire pit area.
- Compact the pea gravel lightly to prevent shifting.
- Regularly top off the pea gravel as needed to maintain the desired depth.
