Rendering View of Haneda Air Port D-Runway

UFC slab factory is located on the opposite shore of Haneda Airport. Our products are shipped to construction site via the ferry boat.

Summary of Haneda Airport D-Runway construction

UFC slab factory

Haneda Air Port D-Runway is under construction as 4th runway which responds to the increase of domestic and international transportation.The new runway is located beside the operated air port. The hybrid structure is composed of the landfill area and the sea-based platform.The sea-based platform is composed of 70m depth of undersea foundation- piles, steel jacket structure and finish pavement. The method was applied to sustain flow of Tamagawa river.

Summary of the UFC slab productionSummary of the UFC slab productionAdvantage of using the UFC slab

Ductal, which is one of the Ultra high strength Fiber reinforced Concrete (UFC), is a new concrete material that possesses excellent characteristics such as ultra high strength, high ductility, high durability, and high fluidity. Ductal also has a noteworthy feature that it requires no reinforcing bars.
