Rubber Mulch Coverage & Depth Guide
Rubber mulch quantity depends on the project area, intended application, required installed depth, and package size.
Use this guide as a starting point for playground and landscaping projects.
Measure the Project Area
For a rectangular area:
Length × Width = Square Feet
Example:
30 feet × 20 feet = 600 square feet
For circular, curved, or irregular areas, divide the project into smaller measurable sections or contact us for help calculating the total area.
Landscaping Depth
Rubber mulch used as landscape ground cover is typically installed approximately 1.5–2 inches deep.
-
1.5 inches provides economical decorative coverage.
-
2 inches provides fuller coverage and additional weed suppression.
Avoid placing excessive mulch directly against plant stems, tree trunks, buildings, or other areas where clearance is needed.
Playground Depth & Fall Height
Certified playground nugget rubber mulch requires a compacted depth based on the equipment’s maximum fall height.
GroundSmart publishes the following ratings:
-
4 inches compacted: protection up to 10 feet
-
5 inches compacted: protection up to 12 feet
-
6 inches compacted: protection up to 16 feet
The selected surfacing depth must meet or exceed the maximum fall height of the playground equipment.
Always follow the current product certification, manufacturer instructions, and applicable playground-safety requirements.
GroundSmart Package Sizes
GroundSmart bulk rubber mulch is available in 1.5-cubic-foot bags.
-
Half pallet: 25 bags / 37.5 cubic feet
-
Full pallet: 50 bags / 75 cubic feet
Estimated Coverage by Package
Landscaping Coverage
| Installed Depth | Half Pallet | Full Pallet |
|---|---|---|
| 1.5 inches | Approximately 300 sq. ft. | Approximately 600 sq. ft. |
| 2 inches | Approximately 225 sq. ft. | Approximately 450 sq. ft. |
Playground Coverage
| Compacted Depth | Half Pallet | Full Pallet |
|---|---|---|
| 4 inches | Approximately 112 sq. ft. | Approximately 225 sq. ft. |
| 5 inches | Approximately 90 sq. ft. | Approximately 180 sq. ft. |
| 6 inches | Approximately 75 sq. ft. | Approximately 150 sq. ft. |
Coverage figures are estimates. Site conditions, settlement, compaction, grading, and installation requirements may affect the final quantity.
Calculate Cubic Feet
Use this formula:
Square Feet × Depth in Inches ÷ 12 = Cubic Feet Required
Example for 600 square feet at 1.5 inches:
600 × 1.5 ÷ 12 = 75 cubic feet
That project would require approximately one full pallet of GroundSmart rubber mulch.
Calculate the Number of Bags
Each GroundSmart bag contains 1.5 cubic feet.
Use this formula:
Cubic Feet Required ÷ 1.5 = Bags Required
Always round up to the next whole bag and then to the available half-pallet or full-pallet package.
Plan for Playground Maintenance
Loose-fill playground surfacing should be inspected and maintained regularly.
Rake displaced material back into high-use areas beneath swings, slides, climbers, and transfer points. Maintain the required compacted depth throughout the complete playground use zone.
Wear mats can help reduce displacement in frequently used areas.
