Sobha Dream Acres is a large residential complex spanning 81 acres, located east of Bangalore, India. This ambitious real estate project features 13 towers of 14 floors, built in record time thanks to the use of precast construction methods, supported by a purpose-built factory equipped with Vollert machinery.

For this project, Dextra provided the owner and contractor, Sobha, with two distinct coupler solutions, supported by threading services.

At Sobha Dream Acres, the Groutec precast solution was used for the swift connection of precast elements, either to a footing or directly to another precast element. This ensured a high-performance connection and significantly sped up installation compared to traditional wet in-situ joint methods.

After casting on the production line, the panel was transported to its final location for straightening and bracing installation. Locally sourced non-shrink grout was then injected into the cavity. After injection, the bracing around the precast panel could be removed after just three days.

Dextra does not supply the grout, as Groutec is designed to be compatible with multiple non-shrink grout brands that can be sourced locally, reducing costs and simplifying logistics.

To complement the precast solution, Dextra also supplied its Bartec solution. Bartec was used throughout Dream Acres to splice reinforcement for both cast-in-place and precast applications, allowing for extended precast element lengths.

To support both solutions, Dextra India managed the rebar preparation operations. Rebars with Bartec-threaded ends were delivered directly to Sobha according to their production schedule. The same threaded bars could be used interchangeably with both Bartec and Groutec couplers, as both solutions utilize the same threading system.
