Fibre Reinforcement for Tunneling

Reinforcing More Than 450 Tunnels Worldwide

BarChip macro synthetic fiber concrete reinforcement has been used to successfully reinforce more than 450 road, rail and utility tunnels worldwide. Our high performance fibres are used in sprayed concrete linings, cast linings, precast segmental linings, precast inverts and slope stabilisation works.

BarChip’s expert team has over 20 years experience across all types of tunnels, ground conditions and concrete mix designs. No matter what the situation, when it comes to fibre reinforcement, our team can give you the answers you need.

40% Reduction in Precast Segmental Linings Cost

Material, labour and production benefits have delivered a 40% decrease in overall segment costs when using our synthetic fiber concrete reinforcement.

Our synthetic fibers are used as a fiber only solution or as a composite with steel reinforcement. Today, a number of guidelines exist to assist designers with segment design.

Sprayed Concrete Linings
Safer, Cheaper and 25% Faster

Steel reinforcement requires expensive machinery, workers to operate under unreinforced ground and can consume up to 30% of the excavation cycle time.

After switching to our synthetic fiber reinforcement projects have experienced a 25% increase in production rate and ensured workers are never under unstable ground.

Cast In-Situ Linings

Barchip’s synthetic fiber concrete reinforced is used in cast linings as the sole reinforcement or as a composite with regular reinforcement. By eliminating the need for concrete cover it may be possible to reduce lining thickness.

How much time would you save by eliminating steel mesh from your cast lining installation?

Invert Segments – 50% Increase in Production Speeds

Project experience has shown that Barchip’s synthetic fiber concrete reinforcement can increase precast production speeds by 50%.

This increase in production output combined with material cost savings, durability improvements and overall performance increases are driving the switch to Barchip’s high performance concrete reinforcement.

Concrete Track Slab

Concrete track slab allows for increased train speeds, reduced track maintenance and increases the track design life by decades.

Barchip’s high performance concrete reinforcement eliminates difficult steel installation, reducing construction time and cost. Furthermore, issues with corrosion are eliminated and problems from stray currents are greatly reduced.
