The client was building a sound stage that required an internal slab and a large strip footing to support 18m high, 70 tonne tilt panels. The strip footing was specified as 600mm thick and 1600mm wide with 8N16 bars top and bottom plus N12@400 ligs. Helix Micro Rebar replaced all conventional reinforcement in the footing with a dosage of 13kg/m3.
The client reduced their schedule considerably as they simply dug the hole and poured the concrete without worrying about steel fixing. Around two weeks were saved on the footing alone.
