Dream Acres is a large residential complex (81 acres area) located east of Bangalore in India. The ambitious real estate program features 13 towers of 14 floors built in a record time thanks to the use of precast construction methods supported by a purpose-built factory powered by Vollert equipment.

For this project, Dextra offered owner and contractorSobha with a two distinct coupler solutions, supported by threading services.

On Dream Acres, Groutec precast solution was used for the swift connection of precast elements either to a footing or directly to another precast element, ensuring a high performance connection and speeding up installation compared to more traditional wet in-situ joint methods.

After casting on the production line, the panel is brought to its final location for straightening and bracing installation. Locally sourced non-shrink grout is inserted into the cavity by injection. After injection, the bracing around the precast panel may then be removed after only 3 days.

Dextra does not supply the grout as Groutec is by design compatible with several non-shrink grout brands that can be sourced locally, generating savings and easing logistics.

To complement our precast solution, Dextra also supplied its Bartec solution. Bartec is used across Dream Acres to splice the reinforcement for cast-in-place applications as well as for precast applications to achieve longer length in precast elements.

To support both solutions, Dextra India took in charge the rebar preparation operations. Rebar with Bartec-threaded ends were delivered directly to Sobha according to their production schedule. Same bars can be used indifferently with Bartec couplers or Groutec couplers as the two solutions take advantage of the same thread system.
