the recent heat wave in Norway and my not taking air out when landing has led to overpressurized tubes - and caused damage. The outer hull went apart were it seems to have been glued together. The inner hull (white translucent foil) is undamaged. Is there any advice about how to repair this damage - and what materials should be used?
Intuitively I would glue the foil togeter, then tape it with repair patches on the outside (possibly with strong ones that stretch over a larger part of the side tube).
Any suggestions?

The photos show how the tarp tore apart.
