We can set-up an inflatable on many surfaces (grass, asphalt, concrete, inside, outside, etc.). It is very important that the location is flat, level, and smooth. It is also imperative that the location allows for overhead clearance from any trees, power-lines, is free of debris, and is easily accessible. Additionally, it is very important to let us know the type of surface, so we can bring the correct anchor system to the job site. We will anchor the unit either by driving stakes into the ground or by using sandbags where stakes cannot be used. When you make the reservation, we will make sure to ask you these questions.
