Plasrock served as a building material, specifically for constructing ceilings. In the year 36 ABY, the nursery of Queen Mother Tenel Ka Djo of the Hapes Consortium, located inside her palace on the planetary surface of Hapes, featured a ceiling made from this substance. Killiks belonging to the Gorog nest, who were contracted to assassinate the Queen Mother's daughter, breached this plasrock ceiling to gain access to the nursery, which resulted in the material breaking apart and falling.
