The underground offers the space which mostly is not available anymore on the surface. Urban traffic is saturated, and rapid mass transport is only possible with a good underground metro network. Service utilities require a dense network of pipes bringing fresh water into the cities and a dense network of sewers to evacuate the wastewater to the water treatment stations. Communication, being the main characteristic of our present world community, needs an extensive network of cables and service stations. The required space is only available underground. Development of modern tunnelling techniques, construction materials and skilled mining people have highly influenced the attractiveness of the underground construction technology. Exploring diverse applications in underground: navigating the parameters for selecting the perfect fiber match.
The process of Sprayed Concrete Lining involves layering shotcrete onto the tunnel's surface, ensuring stabilization and creating a durable tunnel lining.
PSCLs will have a positive impact on the sustainability of underground spaces and increase their viability and potential uses
Dramix is the perfect choice for permanent linings
• Efficient way to create a stable tunnel following a tunnel boring machine (TBM)
• Our fibers are mixed with concrete within a precast plant
Main advantages of the system:
• Increase of productivity, time saving
• Reduction of repair cost of damage segments
• Elimination of storage and positioning of reinforcement cages
• Use of automatic dosing and dispensing equipment linked to the control panel of the batching plant
