We take efforts to prevent any marking of floors or surfaces when installing bleachers. Most surfaces are unaffected by bleachers with the exception of wood floors. When installing on a wood surface, tarps or carpet runners are required to prevent marking of the surface by the rental bleachers.
When installing on grass the area under the frames can turn yellow or even fade completely depending on the length of the rental. However it is very uncommon except for long term rentals.
