As a manufacturer of Expanded Polystyrene (EPS) for over 40 years, we've helped pioneer new and innovative ideas for our products. In construction, Korolite is used for foundations, walls and tapered roofs for both commercial and residential buildings as well as elaborate custom contoured shapes for architectural exteriors and movies sets. We provide Korolite for use in floatation for marinas, fish farms, and floating homes. Korolite expanded polystyrene is also used extensively as a Geofoam voiding under road beds on highways that span over marshy ground.
