Disclaimer

PatioCalc's calculators give estimates for planning and budgeting. They are not a guarantee of the quantity of material you will need or of what a project will cost.

Quantities

Results depend on the measurements you enter and on assumptions such as material density, bag yield, compaction and waste. Real-world conditions vary: ground is uneven, materials differ between suppliers and batches, and installation methods differ. Always check quantities with your supplier and the product's own coverage information before ordering, and consider buying a little extra.

Costs

Prices shown in the calculators are example values that you can edit, not quotes or averages for your area. Material prices, delivery fees and labor rates vary widely by location and over time. Get quotes from local suppliers and contractors for an accurate budget.

Safety and building codes

Structural elements such as footings, slabs and retaining features must meet local building codes and, where required, be designed by a qualified professional. Playground surfacing depth must follow the safety guidance that applies to your equipment and the surfacing manufacturer's tested ratings. Follow product safety instructions, wear appropriate protective equipment, and call your local utility-locating service before you dig.
