If you would like to have a party inflatable installed on concrete or asphalt, you will need to add sandbags for proper anchoring of the inflatable. Some Community Parks require sandbags rather than stakes. Please find out the Parks policy prior to reserving.
You only need (1) order of sandbags per inflatable/tent if they are to be installed on concrete or hard pavement. One order comes with enough sandbangs to anchor the equipment.
