EPS15 Geofoam blocks and Universal Foam Product’s LIP (Leave-In-Place) riser form system were used in the construction of the Columbus School for Girls New Performing Arts Center in Bexley, Ohio. Geofoam was used for the two back riser sections of the 400-seat theater. The Corna Kokosing concrete crew completed the entire foam installation and poured and finished the concrete in just one week. The LIP riser system substantially reduces the time required to create tiered seating in a theater, auditorium or lecture hall setting.
