Tunnel Formwork is a system which allows simultaneous casting of walls and slab in one pouring cycle. Half tunnels can be stripped and moved out to the next phase/level the next day after the pouring. Having faster workflow and being easier to operate with, compared to conventional systems, use of the system can save up to 50% of formwork budget. The system enables you to have smooth concrete surface, dimensional accuracy and eliminates finishing works like plastering. Moreover the system creates good load-bearing concrete structure, which can be applicable for projects in seismic areas.
