The Santoña – Laredo tunnel reduces precast segment costs by 40%.
Excavation speeds in the Mt Ovit Tunnel increased 25% after a switch to BarChip Macro Synthetic Fibers
Cast in Situ final lining of the Legacy Way Cross Passages reinforced with Barchip Synthetic Fiber Concrete Reinforcement.
Barchip Synthetic Fiber Reinforcement used as the primary reinforcement in the Cast In Place Final Lining at the Euclid Creek Starter and Exit Tunnels.
The precast concrete segmental lining of the Harefield to Southall tunnel is solely reinforced with Barchip’s synthetic fiber concrete reinforcement.
Barchip Synthetic Fiber Reinforced Precast Segmental Lining used on the Malaga Rail Tunnel.
Methven (2004) shows that fiber reinforced shotcrete (FRS) has significantly faster development times compared with mesh and bolt ground support systems.
Barchip’s synthetic fiber concrete reinforcement was used as the reinforcement in the sprayed lining, cast in-situ lining and invert segments of the Oliola water tunnel.
Barchip’s synthetic fiber helps deliver substantial material handling and maintenance cost reductions to Helsinki Metro.
