1. What is Pea Gravel?

Pea gravel is small, rounded stones typically about 1/4" to 1/2" in diameter. It's commonly used for landscaping, pathways, and drainage projects due to its smooth texture and attractive appearance.

2. How Does the Calculator Work?

The calculator uses these formulas:

Where:

• \( Area \) — Area in square feet
• \( Depth \) — Depth in inches
• 324 — Conversion factor (27 cubic feet per yard × 12 inches per foot)
• 1.35 — Average weight of pea gravel per cubic yard (tons)

Explanation: The calculation converts area and depth into cubic yards, then estimates weight based on typical pea gravel density.

3. Importance of Accurate Calculation

Details: Proper calculation ensures you purchase the right amount of material - avoiding costly over-ordering or frustrating under-ordering for your project.

4. Using the Calculator

Tips: Measure your area accurately in square feet. For depth, consider both the desired visible layer and any compacted base layer needed.

5. Frequently Asked Questions (FAQ)

Q1: How deep should pea gravel be?
A: For walkways, 2-3 inches is typical. For driveways, 4-6 inches with proper base is recommended.

Q2: Does pea gravel compact?
A: It settles somewhat but doesn't compact like angular gravel. Add 10-15% extra for settling.

Q3: How do I prepare the area?
A: Remove vegetation, level the ground, and install landscape fabric to prevent weeds before adding gravel.

Q4: Can pea gravel be used for driveways?
A: Yes, but requires proper edging and a thicker layer than for walkways. Consider adding stabilizing grids.

Q5: How much does pea gravel cost?
A: Typically $30-$60 per ton, with bulk purchases being more economical than bagged gravel.
