1. What Is Playground Mulch?

Playground mulch is a protective surface material used under and around play equipment to cushion falls and prevent injuries. Common types include engineered wood fiber, rubber mulch, and bark mulch.

2. How The Calculator Works

The calculator uses the formula:

Where:

• \( Area \) — Playground area in square feet
• \( Depth \) — Desired mulch depth in feet
• 27 — Conversion factor (cubic feet to cubic yards)

Explanation: The formula calculates the volume of mulch needed in cubic yards by multiplying the area by depth and converting to cubic yards.

3. Importance Of Proper Mulch Depth

Details: Proper mulch depth is critical for safety. The Consumer Product Safety Commission recommends:

• 9 inches for equipment up to 7 feet high
• 12 inches for equipment 7-10 feet high

4. Using The Calculator

Tips: Measure your playground area accurately in square feet. Determine the appropriate depth based on equipment height. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: How often should playground mulch be replaced?
A: Typically every 1-2 years, or when compaction reduces depth below recommended levels.

Q2: What's the difference between cubic yards and cubic feet?
A: 1 cubic yard = 27 cubic feet. Mulch is typically sold by the cubic yard.

Q3: Can I use this calculator for other types of mulch?
A: Yes, the calculation works for any mulch type, though application rates may vary.

Q4: How do I measure an irregularly shaped playground?
A: Break it into rectangles, calculate each area separately, then sum them.

Q5: Should I account for settling?
A: Yes, consider adding 10-15% extra to account for settling over time.
