How to Use the Rubber Mulch Calculator
Using our rubber mulch calculator ensures you purchase the exact amount of material for your playground or landscaping project. Unlike wood mulch, rubber mulch does not decompose, making it a one-time investment that requires precision during the planning phase.
Standard Depth Recommendations
Playground Safety: For critical fall heights, a depth of 6 inches is standard for most residential and commercial playgrounds.
Garden Landscaping: A depth of 2 to 3 inches is usually sufficient for weed suppression and aesthetic purposes.
Erosion Control: Areas prone to runoff may require 4 inches of depth for better stabilization.
Calculation Examples
Example 1: The Rectangular Playground
Suppose you have a playground area that is 20 feet long and 15 feet wide. To meet safety standards, you want a depth of 6 inches. Using a standard 0.8 cubic foot bag size:
– Area: 20 * 15 = 300 sq. ft.
– Volume: 300 * (6 / 12) = 150 cubic feet.
– Bags: 150 / 0.8 = 188 bags.
Example 2: The Circular Garden Bed
You have a circular tree surround with a radius of 5 feet and want 3 inches of mulch coverage.
– Area: π * 5² ≈ 78.5 sq. ft.
– Volume: 78.5 * (3 / 12) = 19.6 cubic feet.
– Bags: 19.6 / 0.8 ≈ 25 bags.
Why Rubber Mulch Weight Matters
Rubber mulch typically weighs approximately 20 lbs per cubic foot (depending on the brand and nugget size). Understanding the total weight helps you plan for transport or delivery. If your project requires 100 cubic feet, you are looking at roughly 2,000 lbs (1 ton) of material.
