If as you say, the panels have been fixed with asphalt/bitumen
adhesive (tile adhesive) this can be softened by heating the panel
with infrared lights of with a large heating gun and then the panel
can be pried from the wall. The length of heath application and the
temperature depend on the thickness of the panel and on the age of
the adhesive. At least, it worked for me.
