Can a school inflatable go on blacktop, grass or the gym floor?
Measure the open space you can actually give us, not the whole field. Each inflatable needs extra room around it for the blower, the anchors, the way in and out, and an adult watching the line. Keep a lane open for emergency vehicles and for students moving between stations.
On blacktop, the first question is how that exact unit gets anchored. We only use sandbags or ballast when the manufacturer allows it. In the gym, measure the height under the lights, beams and basketball goals, and check the doors and hallway turns. Our guide to bounce house on concrete, grass, or indoors covers each surface.
Before the day, ask the front office where we can unload, what time we can get in, and whether the school needs a COI.
