Safety Limitations

Important Safety Notice

• Maximum fall height protection: 5 feet
• Not recommended as primary safety surfacing
• Presents mobility challenges
• Requires consistent maintenance
• Can be displaced easily by play activity

Why Pea Gravel Isn't Ideal

• Scatters easily outside containment areas
• Can become projectiles when thrown
• Difficult for wheelchair access
• Requires frequent depth checking
• May hide sharp objects or debris
• Can be swallowed by small children
• Needs regular raking and leveling

 Using the Calculator

For Installation

• Include proper drainage layer
• Account for containment borders
• Calculate new material needed
• Factor in settling and displacement

 Installation Requirements

Base Preparation

• Remove existing material
• Install proper drainage system
• Add geotextile fabric barrier
• Ensure adequate containment
• Maintain minimum depth throughout

Maintenance Considerations

• Regular depth checks
• Frequent raking
• Material replacement as needed
• Border maintenance
• Drainage system inspection

 Better Alternatives to Consider

• Engineered Wood Fiber
• Rubber Mulch
• Poured-in-Place Rubber
• Rubber Tiles
• Artificial Turf Systems

 Professional Recommendations

If Using Pea Gravel

• Install only in limited areas
• Use proper containment systems
• Maintain strict depth requirements
• Install adequate drainage
• Regular maintenance schedule
• Consider mixed surfacing systems

Installation Tips

• Never install over concrete or asphalt
• Ensure proper drainage slope
• Install border containment first
• Maintain consistent depth
• Add drainage layer beneath
