How do you view the development of tunnel projects in the country?
Tunnel projects in the country are experiencing steady growth, fueled by the rising demand for improved urban infrastructure and transportation systems. As urban areas continue to expand, there is a greater need for underground solutions such as metro tunnels, roadways, and utility systems. Tunneling is essential for reducing surface congestion and creating efficient, sustainable transport networks. While the country is still adopting new materials and techniques, there is a growing interest in advanced materials like Glass Fiber Reinforced Polymer (GFRP) to enhance durability, efficiency, and sustainability, particularly in challenging environmental conditions.
How is technology evolving in tunneling? What are the new technological trends?
Tunneling technology is advancing rapidly, with several key trends reshaping the industry. Tunnel Boring Machines (TBMs) have become more automated, making it possible to tackle complex geological challenges. The integration of digital tools such as geotechnical monitoring systems and real-time data analytics is enhancing decision-making processes and boosting safety. Additionally, GFRP materials are increasingly being utilized for reinforcement due to their lightweight, corrosion-resistant properties, which help reduce maintenance costs and extend the lifespan of tunnel structures. Automation, AI, and robotics are also transforming tunneling, making it safer, faster, and more efficient.
What are the major technologies and solutions offered by the company in tunnel projects?
Our company Dextra offers a comprehensive suite of advanced solutions for tunnel projects, including high-performance GFRP-based products such as rock bolts, reinforced rebar, and anchors. These GFRP solutions are specifically engineered to deliver exceptional corrosion resistance and long-term durability in demanding underground environments. Additionally, we provide Dextra's innovative cuttable solutions, which include cuttable reinforcement bars and ground anchors. These are particularly effective in the longitudinal direction of tunnels, offering temporary stabilization during the construction phase. These technologies are designed to enhance the overall efficiency and safety of tunneling operations, while ensuring minimal environmental impact and optimizing project timelines.
What are the major challenges encountered in tunneling? How are your solutions minimizing the challenges?
Tunneling projects face challenges such as ground instability, water infiltration, corrosion, and high construction costs. Traditional materials like steel are vulnerable to rust and decay, particularly in wet or chemically aggressive environments. Our GFRP solutions address these issues by offering corrosion resistance, ensuring long-term durability and reducing maintenance needs. Additionally, the lightweight nature of GFRP products simplifies material handling and transportation. Our advanced monitoring systems further enhance safety by providing real-time data that enables proactive measures to address potential issues before they become serious.
How are your solutions playing a major role in tunnel projects?
Our solutions have been integral to numerous tunneling projects. For example, permanent rock bolts made from GFRP have been used in NATM tunnels to provide vital structural support while eliminating the risk of corrosion. In metro and railway tunnels, our GFRP rebar and anchors have reinforced tunnel linings, enhancing durability and stability. We’ve also contributed to underwater tunnels and marine port projects, where the corrosion-resistant qualities of GFRP are crucial for maintaining structural integrity in harsh, wet conditions. These projects have benefited from our technology’s ability to reduce costs and ensure long-term reliability.
How do you look at the opportunities for your technologies and solutions in the future?
The future for our GFRP technologies in tunneling and infrastructure projects is very promising. With the global shift towards sustainability and durability, GFRP will play a crucial role in reducing the environmental footprint of construction projects. Thanks to its lightweight, corrosion-resistant, and long-lasting attributes, GFRP is becoming a key material in sustainable infrastructure development. We foresee growing opportunities in sectors such as underground utilities, marine ports, tunnel reinforcement, and bridge construction, particularly as more countries embrace environmentally friendly, durable materials. As awareness and regulations around sustainable materials evolve, GFRP is likely to become the material of choice for tunnel reinforcement worldwide.
