Excavation speeds in the Mt Ovit Tunnel increased 25% after a switch to EPC BarChip Macro Synthetic Fibers
BarChip structural synthetic fiber was chosen to meet the design life requirements, eliminate the risk of salt water corrosion and improve the structural integrity of the substrate.
TCP designs optimise the dimensions of concrete pavement slabs. TCP slabs are smaller than typical concrete slabs which allows them to better share the load of heavy vehicles
Methven (2004) shows that fiber reinforced shotcrete (FRS) has significantly faster development times compared with mesh and bolt ground support systems.
Daily concrete complete rates increased from 800m2/day to between 1200m2 to 1600m2/day with EPC’s concrete reinforcement.
