In the summer of 2001 PL Beton has produced 47 balcony slabs in CRC for a project called "Vognfjederen" in Copenhagen. The balcony slabs have the dimensions of 3.5x1.8 meters and a thickness of between 50 and 65 mm. The slabs are supported at 3 corners and have a Wisa-floor surface to prevent slipping.
