Formex, a polymeric substance, served as a construction material for numerous architectural projects, such as columns and roads. Due to its fluid nature, it could be poured directly into molds at construction sites, enabling the creation of diverse shapes and structures. It saw widespread use in buildings across various locations, including those on the planet Etti IV, within Bonadan's Spaceport Southeast II area, on the world of Harridan, in Vandalar City located on Reaper's World, in the city of Kavila on Dalos IV, and also as structural supports and flooring on Mesa 291 of Bothawui. The Alliance to Restore the Republic frequently utilized shaped formex, together with permacite, as construction materials for their remote outposts.
