The Banagher Double-step terracing unit for stadia, spectator stands and auditoriums is an innovative carbon-efficient precast unit which offers several benefits over traditional single-step units: it provides thinner section properties and the lighter, stiffer section enhances performance in terms of strength, deflection and frequency analysis. It incorporates the recycled material Ground Granulated Blastfurnace Slag (GGBS), and its reinforcing steel has a recycled content of 92%. Its lighter section reduces transport and installation energy requirements, as well as jointing mastic usage.
