Rubber Mulch vs Wood Mulch

Rubber Mulch Benefits

  • Lasts 10-12 years without replacement
  • Won't attract termites or carpenter ants
  • Doesn't float away in heavy rain
  • ASTM certified for playground fall protection

Considerations

  • Higher upfront cost than wood mulch
  • Can get hot in direct sunlight
  • Doesn't add nutrients to soil
  • Rubber smell initially (fades over time)

Pro Tips

  • Install landscape fabric underneath to prevent weeds and keep mulch clean
  • For playgrounds, follow ASTM F1292 fall height guidelines (6" minimum depth)
  • Rubber mulch doesn't decompose - one-time installation lasts 10-12 years
  • Hose down periodically to remove dust and debris; won't wash away like wood

Common Questions

How much rubber mulch do I need?

Multiply area by depth in feet. A 200 sq ft area at 3" deep needs about 50 cu ft (63 bags).

How deep should rubber mulch be?

2-3" for landscaping, 6" minimum for playgrounds (ASTM fall protection).

Is rubber mulch worth the cost?

Yes long-term: one-time cost vs replacing wood mulch annually for 10+ years.

Does rubber mulch attract bugs?

No. Unlike wood mulch, rubber doesn't attract termites, ants, or other insects.

How the Calculator Works

The calculator multiplies your area (length × width) by the depth to get total cubic feet needed. We then divide by the standard bag size (0.8 cu ft) to get your bag count. The cost comparison assumes wood mulch needs annual replacement while rubber mulch lasts 10-12 years.

Formula

Cubic Feet = Length × Width × (Depth ÷ 12)

Bags = Cubic Feet ÷ 0.8 (standard bag size)
