NLTF Modular Tunnel Form is designed to serve as both half-tunnel and full-tunnel system. It has expanded span & height modularity. It's unique design enables the system to serve for large spans without using any table form at the mid-span.

Advantages:

• No separate production of walls and slabs, so no need for horizontal working space.
• Backwalls are easily integrated in the production cycle.
• Safety on site is easy to achieve.
• Prefabricated elements can easily be poured in.
• Only a small site needed as there is only a small stock necessary (reinforcement and prefab elements).
• The end deckpanels can be shifted on the bearing beams, so a tapered bay can be realized in a very economical way.
• With the special rooflock the tunnel can be stripped as a halftunnel or as a fulltunnel.
• The joint in the deck between the two halftunnels is reduced to almost zero.
• All bolts and jacks have the same size so only one tool necessary.
• The vertical panel jacks are easily to replace.
• The bottom profile of the vertical panel gives an easy view on the kickerline.
• By use of massive angle-profiles at the deck joint reduces repairs between projects.
