London Wall Place is large a double tower office development in London built close to the Roman City Wall historical monument.

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

The concept was to install Groutec couplers in each panel reinforcement, at the bottom of the vertical bars previously prepared with 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 cavity of the coupler, in order to create the rebar connection. Groutec is not reliant on a specific type of grout. Rather, several different brands of grout can be used, facilitating local scouring and helping to keep costs low. The bracing around the panel is then removed after the grout has achieve a prescribed strength.

After straightening and bracing of the precast panel, non-shrink grout is inserted into the cavity by injection. Dextra does not supply grout as Groutec is by design compatible with several brands that can be sourced locally, generating savings and easing project management.After injection, the bracing around the precast panel may then be removed after only 3 days.

The use of Groutec for precast panel is a time-saving and economical way to quickly take advantage of the precast technology. For similar application video, please check The Plum Central Station project page.

Icon Siam complex, located on the right bank of the Chao Phraya river in the West of Bangkok, is a new multipurpose commercial/residential complex consisting of two highrise buildings and a shopping mall. This new massive project aims to give back its glamour to the banks of the Chao Praya river.

The two towers are expected to reach 280m (SuperLux Tower) and 315m (Magnolia Tower) respectively. The Magnolia Tower will thus be slightly taller than the MahaNakhon Tower, Bangkok’s tallest building since 2015.

Dextra is supplying Thai-Obayashi (contractor of the shopping mall structure) and Italian-Thai (contractor of both towers) with its Bartec rebar splicing solution.

Dextra engineers performed operator trainings and do preventive maintenance directly on site to guarantee maximum output in thread production.

In total, more than 800,000 บาร์เทค rebar couplers and 20,000 Bartec บาร์หัว are being used in foundations and superstructure in the following applications:

L-shaped dowel bars (wall-slab connections)

This is a typical application used in foundation D-Walls to avoid protruding rebar. it is also used in the superstructure to allow the sliding formwork to climb up without any disturbance

Substitution of hooked bars with end anchors

When the wall reinforcement is especially congested, the use of Headed Bars (also called end anchors) allows to anchor the reinforcement in the wall without the need to produce hooks.

Double-ended connection in shear-walls

This solution allows to create a continuity inside the column or wall by bridging two horizontal slabs or beams.

Welded couplers for composite structures

Sometimes it is necessary to start reinforcement from the steel structure. In that case, weldable couplers are the ideal solution: Made of a low-carbon steel, they can be welded easily and allow connection to a threaded rebar.

ONE Limassol Tower is a commercial building and a new landmark of Limassol, Cyprus. The project aims to position the island on the international luxury property market, enhancing the attractiveness of the country for foreign investment by offering world-class residence, amenities and services. This will also boost Cyprus’ economy, while increasing local employment opportunities.

At 170 meters above ground with 33 storeys in total, the ONE Limassol Tower is the tallest seafront residential project in Europe. The building will host 83 luxurious apartments, including a three-storey penthouse.

For the reinforcement of this landmark building, Dextra delivered its rebar couplers and bar-end preparation machine sets to the contractor J&P and ACC JV, which is a joint-venture between Joannou & Paraskevaides Group (J&P) and Arabian Construction Company (ACC).

More than 60,000 Bartec couplers were used for rebar splicing in rafts and vertical parts of the building.

The completion of this iconic project is scheduled in 2019.

The new headquarters building of the National Bank of Kuwait is a 300m-tall tower that covers a total floor area of 127,000m2 with a design concept inspired by pearl shells and located in the heart of Kuwait City’s financial district.

The main construction comprises composite concrete and steel, while the cladding on the fins and glass façades is predominantly glass-reinforced concrete.

Dextra took part in reinforcing the concrete structure of the building by providing these solutions:

Act One | Act Two Tower is a premium residential project in the Opera District of Downtown Dubai.

The project consists of two towers called Act One (52 stories) and Act Two (46 stories).

With their prime location, these residential towers offer views of the Dubai Fountain and the Burj Khalifa and they are few minutes away from Dubai Metro and from major attractions like the Dubai Mall and the Souk al Bahar.

For this exceptional residential project, Dextra was entrusted with the reinforcement of the buildings’ structures, including raft foundations, columns, slabs and construction joints.

150,000 Bartec rebar couplers along with rebar preparation machines were delivered to the construction site.

Bartec rebar couplers help speed up the construction with a faster and more convenient way of connecting rebars than the traditional rebar lapping method.

The thread on the rebar can be extended from a half-coupler to a full coupler length, allowing to perform the connection without any bar rotation.

The project is scheduled to be completed in November 2020.

The Floresta Gardens project involves construction of the towers inside The Pearl Qatar.

The project consists with the construction of mid-rise residential towers and villas within three gated villa communities, including a 2,452-square meter retail center. The precinct has a gross floor space of 267,471 square meters, 145,967 square meters of developable land, and 5,000 residential units.

In the precast construction of the towers, Dextra Groutec played a significant role. Over 30,000 Groutec L couplers in sizes 20 mm to 40 mm were inserted inside columns for vertical connections on the construction site.

Groutec precast coupler is an innovative solution for fast and easy connection of precast concrete elements. It is widely used in residential and commercial construction projects around the world.
