The condominium, which is located near the Chaopraya river on Rama 3 road in Bangkok, Thailand, contains 484 units.

Grouted mechanical sleeves were used to join the precast elements, and Groutec couplers, which were inserted inside the shear wall and bearing wall, played an essential role to ensure the reinforcement continuity with dry joints.

The half-grouted mechanism of Groutec L and S sleeves, which feature a threaded end on one side, ensured accuracy and reduced mistakes throughout the grouting process,” stated Mr. Janeboon Leepipatnavit, Project Director of Taveeporn Technology Co., Ltd., the project’s contractor.

The construction required fewer workers and supplies such as rebars and concrete, resulting in a shorter construction period and less noise and waste.

Cairo Metro is the rapid transit system in Greater Cairo, Egypt. It was the first of three full-fledged metro systems built in Africa, as well as the first in the Arab world.

The system currently has 74 stations, 3 of which are transfer stations, with a total length of 89.4 kilometers. There are 3 operating lines in the system, numbered from 1 to 3.

Cairo Metro Line 4 will be built as a new underground line that will help to alleviate traffic congestion. Phase 1 will run for 19 kilometers and include 16 stops, connecting the heart of Greater Cairo to Giza’s pyramids.

Dextra has supplied turn-key solutions for the reinforcement of the diaphragm walls.

• 450,000 Bartec+ couplers
• 42 GFRP soft-eyes

It is projected to be Egypt’s major tourist transportation line, with service up to the Pyramids area beginning in 2024.

Etihad Rail is a 1,200-kilometer railway project that will be the first national freight and passenger railway network in the United Arab Emirates (UAE).

The railway project is expected to be a sustainable alternative for freight and passenger transportation throughout the Emirate’s urban and rural areas.

It is expected to carry approximately 16 million passengers and 50 million tons of cargo.

Dextra is currently supplying various engineered solutions for the second phase of rail network construction which includes excavation of the GCC’s longest rail tunnel.

• Bartec couplers for concrete structure reinforcement.
• Sonitec tubes for the crosshole sonic logging testing of foundation piles.
• Steel and GFRP rock-bolts for rock stabilization.
  Umbrella pipes for stabilizing tunnel headings.

Delhi Metro is the largest and busiest rapid transit system in India, serving Delhi and its satellite cities. Phase 3 will add 35 underground stations and 3 new lines.

The total length of the 54 km underground corridors in Phase 3 are more than the total underground sections in phase 1 & 2, making it a challenge for construction in this densely populated city.

Glass Fiber Reinforcing Bars (GFRP) have been used for the numerous “soft-eyes” in diaphragm walls of several stations, which has facilitated the excavation of underground tunnels by TBMs.

Astec™ Active Anchors (AAA) have also been used as temporary stressed anchors in retaining walls in replacement of traditional strutting, this enhancing greatly the accessibility during excavation work.

Moreover, Bartec™ rebar couplers and Dextra post-tensioning bar systems were installed in various parts of the construction.

The West Gate Tunnel is a four kilometer toll road in Melbourne, Australia that will link the West Gate Freeway with the Port of Melbourne and CityLink via twin tunnels, a bridge and an elevated road section.

The viaduct is being built on 300 post-tensioned concrete piers of varying heights. For each pier, vertical post-tensioning bars are connected to a dead anchorage embedded in the foundation of the pile.

Dextra was in charge of the fabrication of more than 1,000 tons of such bars, grade 1080, with nominal diameters of 72mm and 55mm, and 7,500 anchorages, installed on site by our partner, Freyssinet Australia.

MSG Sphere is a 18,000 seat, sphere-shaped music and entertainment venue being built in Paradise, Nevada, near Las Vegas Strip.

The 360-feet tall and 516-feet wide sphere is being built on 18 acres off Sands Avenue between Manhattan Street and Koval Lane.

Dextra Bartec rebar couplers and headed bars have been used to connect and reinforce columns, core walls and beams of the building’s structure.

Bartec® mechanical splicing system is certified in the USA as “type 2” with ICC-ES and meets CALTRANS “Ultimate” performance requirements.

Developed by Aurobindo, Galaxy Towers is a 24-storey precast office building in Hyderabad, India.

The project is expected to be built in half the time of a comparable conventional cast-in-situ construction, illustrating how the precast technology has gained ground thanks to its efficiency.

Dextra supplied a critical part of the precast structure of this special building: the Groutec coupler, a half-grouted sleeve designed for the connection of precast elements.

By installing Groutec couplers into the precast columns and walls at the precast factory, the fast and safe connection of walls or columns is achieved by injecting cementitious non-shrink grout into the sleeves at site.

More than 100,000 Groutec couplers have been delivered.

Upon completion, it will be the tallest office tower in India built with precast technology.

The Metro Tunnel is a major enhancement to Melbourne’s rail network, a multibillion-dollar project comprising the design and construction of twin nine-kilometer tunnels and five underground stations.

The stations are designed based on the architectural character of the local area.

Dextra has been selected as a one-stop solution supplier, thanks to its wide range of products.

The numbers are impressive:

• 400,000 Griptec rebar couplers
• 5,300 GFRP Combination Bolts
• 900 GFRP soil nails
• 16 ojos suaves

Dextra was able to support and share their expertise on GFRP at design stage and produce the GFRP solutions as per the owner expectation.

La central nuclear Hinkley Point C (HPC) es uno de los proyectos más grandes y tecnológicamente más complejos de Europa.

HPC es la primera central nuclear construida en el Reino Unido en una generación, y su construcción requiere una mano de obra altamente cualificada y las mejores soluciones de construcción e ingeniería.

The HPC Project is located in Somerset, South West England, and will consist of two nuclear reactors capable of generating 3.2GW of low-carbon electricity.

The new power station is being constructed in the same area as the existing Hinkley Point A and B stations. The former has ceased operation for quite some time, while the latter is scheduled to begin decommissioning in 2023.

Battersea Power Station, fully decommissioned almost 40 years ago, is being redeveloped in one of UK’s biggest ever construction projects.

The seven-phased redevelopment venture is estimated to be worth £8bn ($13bn).

The 3rd phase consists in the creation of the so-called ‘Electric Boulevard’, which will include a connection to the Northern Line Extension station, more than 1,300 residential units, a 160-room hotel, retail spaces, restaurants and leisure facilities.

The wide range of concrete reinforcement solutions provided by Dextra was proven to be ideal for this iconic project.

Different ranges of couplers have been supplied for cast-in-situ, precast and repair applications, specifically:

• 100,000 Griptec and Rolltec cast-in-situ couplers
• 30,000 Groutec precast couplers
• 3,000 Unitec bolted couplers
