Playground Rubber Mulch Calculator

Why Choose Rubber Mulch?

Rubber mulch offers several advantages for playground surfacing:

• Excellent shock absorption
• Weather resistant
• Minimal compaction compared to other materials
• Available in various colors
• Long-lasting durability
• ADA accessible when properly installed

 Why 6 Inches?

Though rubber mulch compacts less than wood fiber, some displacement occurs through:

• Regular playground use
• Weather conditions
• Children's activities
• Natural settling

Starting with 6 inches ensures maintaining the critical 4-inch minimum depth even after normal wear and displacement.

Important Safety Considerations

Fall Height Protection

• 4-inch minimum depth protects falls up to 8 feet
• 6-inch depth protects falls up to 10 feet
• Always verify fall heights of your specific equipment

Installation Requirements

• Install over a properly prepared, well-draining base
• Use containment borders to prevent migration
• Extend surfacing at least 6 feet beyond equipment in all directions
• Never install directly over concrete or asphalt
• Consider adding a weed barrier underneath

 Maintenance Tips

• Rake periodically to maintain even distribution
• Check depth regularly, especially in high-traffic areas
• Add material as needed to maintain proper depth
• Install wear mats under swings and slide exits
• Remove any foreign objects promptly
