Intelligent Engineering's Sandwich plate System is a structural composite comprised of two metal plates bonded with a polyurethane elastomer core. The resulting material is more robust than stiffened steel plate, and lighter, and faster to erect than reinforced concrete. When used as an alternative to concrete, SPS Terraces offer comparable performance at less weight and the added benefits of greater durability, dampened vibration and built-in acoustic insulation. SPS Terraces were recently used to expand seating at the Aquatics Centre in London's Olympic Park from 5,000 to 20,000 for the 2012 Olympics.
