Looking to install outside in a swing set play area. What’s the best base?

We recommend installing our flooring over any hard, flat surface. Concrete, asphalt, and compacted crushed granite are examples. A concrete pad would provide the best results for installing our flooring and keep your children safe, but you can also use compacted crushed granite if the swing set is over grass. We would recommend removing the existing grass and then adding in crushed granite. You would then compact this crushed granite layer to create a flat, hard surface. This will help to ensure that the tiles lay properly and help to keep your kids safe while at play.
