When we say we understand tunnelling processes, we really mean it. Because we consider tunnelling projects from a holistic standpoint, we are able to provide large savings in carbon and costs at every stage, helping customers to reach overarching financial and environmental targets.
Saving carbon and costs
From the very beginning of the design process, we help our customers build clever through the use of modern, low-carbon technology combined with our expert industry know-how. State-of-the-art design approaches to construction chemicals, sprayed concrete, waterproofing membranes, and other tunnel linings build on digital monitoring techniques to provide 20-25% reductions in material use and up to 55% reductions in carbon when employed correctly. In fact, using our ultra-low carbon sprayed concrete, CO2 savings of up to 70% can be achieved thanks to no steel fibres and efficient use of accelerators, admixtures, aggregates and binders.
During the tunnelling construction phase, our advanced solutions such as battery-electric vehicles and digital twins make it easy to conduct safe and sustainable tunnelling activities. Normet SmartDrive BEVs optimize energy consumption and allow the use of renewable energy underground, taking a step towards future carbon-neutrality. We make it simple to switch from fossil fuelled tunnel construction equipment by ensuring process efficiency and safety throughout our portfolio.
Developing the digital underground
Making the most of new technology is what we do best. Normet patented SmartScan and SmartSpray solutions provide operators with real-time 3D pictures of the tunnel surface – a digital twin – to prevent over- or underspray of concrete thanks to ergonomic, automated, robotic action. Efficient use of material reduces costs and environmental impact. And VR simulator training including EFNARC certification ensures the high-level skills of tunnel construction teams. We are constantly developing our digital offering to make the most of new high-tech possibilities underground.
Tunnels are vital parts of our societal infrastructure. We provide systems and services to enhance and extend the use of underground space. Normet injection technologies and rock reinforcement techniques help our customers manage the unexpected during and after construction. Our solutions extend to refurbishing, repurposing, and rehabilitating equipment and tunnels, creating a low-carbon circular economy that creates value for all stakeholders over lifetimes.
