Cut-and-cover method
Economical
- Fast repositioning, because adapting the steel panels to new geometries is easy (no time-consuming modifications to the traveller)
- Many system components are rentable
- System beams, walings and struts can be arranged in variable configurations, so optimum use is made of each item of equipment
Safe
- With integrated working platforms and ladderways adapted to site specifics
- Clearly structured documentation from assembly drawings through to risk assessment
Fast
- Quick adaptation of the steel panels to new tunnel geometries
- Depending on requirements, we can offer anything from a simple repositioning solution to an all-hydraulic operation
- Smooth construction progress
- Optional: Short set-up times, because components of formwork and load-bearing systems are pre-assembled

Innovative adjusting mechanism
Adapting to different cross-sections is simple and no disassembly is needed.
Fast tunnelling
The patented adjusting mechanisms of the panel make the SL-1 Volto faster to work with than conventional steel panels.
