Tunnel form is a formwork system that allows the contractor to cast walls and slabs in one operation in a daily cycle. It combines the speed, quality and accuracy of factory/off-site production with the flexibility and economy of in-situ construction and is recognised as a modern method of construction (MMC).
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.
