Nathani Heights is a 72-storeys skycrapper in Mumbai. With a total height of 262 meters it is among the 30 tallest building in the city. The construction of the building started in 2012 and will be completed in 2018.

For this project, Dextra supplied its famous Bartec rebar coupler solution. Bartec is the main rebar coupler solutions in India, satisfying all technical requirements even in seismic areas.

As in other highrise building, rebar couplers have been used for large diameter rebar connection in vertical applications such as columns and corewalls (bar to bar vertical connection).

Rebar couplers were also used for slab connections. In that case, the coupler is pre-positionner flush with formwork (allowing climbing formwork to go up). After casting, a threaded rebar is simply screwed inside the coupler to create the starter bar.
