Versatile Solutions

Reinforced Polymer (GFRP) solutions are widely and frequently used for several applications in civil engineering due to its numerous benefits the product offers; in comparison to alternative conventional materials in the market. 

Some of the important features the product offers are the cut ability: A ¼ of the weight and 2x stronger in tension compared to steel rebar.  The product is corrosion-free with additional benefits of resistance to acidic and alkali elements.

This light weight material is ideal for temporary applications and comes with hundred years of life time, hence suitable for permanent applications. 

A perfect choice for mining and tunneling, this composite technology has successfully been used for decades. This innovative material is also available for soil nails and tieback ground anchors. 

A perfect showcase of its flexibility and innovation is the latest GFRP solutions for the Melbourne Metro Tunnel project; a major enhancement to Melbourne’s rail network. For this multi billion dollar project, comprising the design and construction of twin nine km tunnels and five underground stations has been supported by Dextra. The project team with its technical expertise on GFRP at design stage and manufacturing was successfully handled by the company.

5300 Combination Bolt pcs used as temporary measure to secure the center walls of the 19m wide cavems during construction of two conventional 7m tunnels.

900 Soil nail pcs used to secure the station walls. The anchors can remain in the ground as materials properties which allow for easy cutting at later stage.

59000 meters Soft eyes enabled disruption –free penetration of the Tunnel Boring Machines (TMB) through the thick concrete diaphragm walls of five station.
