The Car Servicing Building at 2 Kung Chong Road in Singapore is a mixed-use, 7-story facility featuring a basement car park, a car servicing center, and office space. The building will be occupied by the Automobile Association of Singapore.

This project, built by Zhengda Corporation Pte Ltd, utilizes precast technology to achieve faster construction cycles. The precast elements were produced by the Malaysian precaster Eastern Pretech.

For this project, Dextra supplied approximately 6,000 Groutec couplers to the precaster, which were embedded into shear walls and column elements.

The precast elements were then transported to the site and reconnected to protruding reinforcement by injecting non-shrink grouting mortar. Bracing around the precast elements is typically removed within three days of the grout injection, significantly reducing assembly time.

Nathani Heights is a 72-story skyscraper in Mumbai. With a total height of 262 meters, it is among the 30 tallest buildings in the city. Construction began in 2012 and was completed in 2018.

For this project, Dextra supplied its renowned Bartec rebar coupler solution. Bartec is the leading rebar coupler solution in India, meeting all technical requirements, including those for seismic areas.

As with other high-rise buildings, rebar couplers were used for large-diameter rebar connections in vertical applications such as columns and core walls (bar-to-bar vertical connections).

Rebar couplers were also used for slab connections. In this case, the coupler was pre-positioned flush with the formwork, allowing the climbing formwork to progress upwards. After casting, a threaded rebar was simply screwed into the coupler to create the starter bar.

Louvre Abu Dhabi is an innovative art and civilization museum located north of Abu Dhabi city, the capital of the United Arab Emirates. It is the largest museum in the Arabian Peninsula, with a total area of 24,000 square meters. Louvre Abu Dhabi officially opened its doors on November 11, 2017.

For this project, Dextra was involved in concrete works between 2013 and 2014, supplying its Bartec rebar coupler solution to Arabtec for all rebar connections in the raft and columns. Couplers were also used to create temporary openings in the reinforcement structure, allowing the passage of workers and equipment. A total of 110,000 Bartec rebar couplers were supplied for this project.

The Bartec solution is approved by the Dubai Central Laboratory (DCL), making its use possible in the UAE. All threading services to prepare the rebar used at Louvre Abu Dhabi were performed by Dextra’s network of distributors.

Business Garden Bucharest is a modern mixed-use Class A office complex featuring retail spaces paired with commercial and public services on the ground level. The name Business Garden stems from its integrated, spacious green area—a garden connecting the buildings with designated recreation spaces. A generous lawn, pedestrian pathways, and benches with free Wi-Fi invite office-goers to work or take a refreshing break outside. The complex is LEED Platinum pre-certified.

To support tenants’ everyday needs, Business Garden Bucharest’s offices are designed with an efficient layout, high-quality finishes, and sustainable solutions aligned with LEED Platinum green certifications.

For this project, Dextra supplied its Fortec rebar coupler solution. Fortec consists of a standard rebar coupler that can be used for both standard and position splices, connecting two rebar ends that have been previously enlarged and threaded. Fortec is especially suitable for seismic environments, making it ideal for buildings in the Bucharest area.

Fortec couplers were used to provide superstructure vertical connections. Their compact design helps reduce congestion caused by rebar lapping. Additionally, Fortec couplers allowed for temporary openings, enabling worker and equipment movement around the reinforcement. Before casting, the continuation bars were simply connected to the couplers, closing the temporary gaps.

London Wall Place is a large double-tower office development in London, built close to the historic Roman City Wall.

For this project, Dextra provided a technical solution for the fast installation of precast wall panels to contractor Byrne Bros and main consultant WSP.

The concept involved installing Groutec couplers in each panel’s reinforcement, at the bottom of the vertical bars, which were previously prepared with the Rolltec thread system, available in the UK through our distributor network.

After bracing the precast panel in its final position, non-shrink grout is injected into the coupler cavity to create the rebar connection. Groutec is not reliant on a specific type of grout, allowing for the use of different brands, which facilitates local sourcing and helps reduce costs. Once the grout reaches the prescribed strength, the bracing around the panel can be removed.

The use of Groutec for precast panels is a time-saving and cost-effective method that maximizes the benefits of precast technology. For a similar application, check out the Plum Condo project page for reference videos.
