High performance rebar connectors are required in order to reinforce the structure of these two iconic towers: Dextra was entrusted with this job, and provided 70,000 Griptec couplers, well-known for their unrivaled performance in tension, compression, and fatigue conditions.

Supported by high-productivity rebar preparation equipment, Griptec couplers were installed in columns, beams, starter bars for slabs and other parts of the structure.
Furthermore, the homogeneity of concrete within the buildings’ bored piles was tested using the Cross Sonic Logging (CSL) methodology, requiring a transmitter and a receiver to be inserted in parallel water-filled tubes down the pile depth to measure the speed of ultrasonic pulses and ensure the integrity of the foundations.

Dextra’s SONITEC tube facilitated the test thanks to its easy installation into reinforcement cages: 4,000m of ST50 sonic tubes were provided for this project.

Upon completion, anticipated to be in 2022, the City Tower will become one of the tallest residential projects in London and the United Kingdom.

Urban Deca Homes Ortigas is one of the largest residential projects currently developed in the Philippines, involving the construction of 22 residential buildings with 19,000 one- and two-bedroom units on a 13-hectare property in Metro Manila, Philippines.

The developer is expecting to appeal to the young working families of the surrounding areas of Ortigas, Eastwood and Vertis North, offering affordable accommodations starting from as little as 30,000 USD per unit.

Dextra has supplied almost 150,000 Groutec couplers for 20 of the residential buildings: model S25 and S28 are used to connect rebars in load-bearing shear walls.
This typology of mechanical splices is designed to simplify installation of precast concrete elements such as panels or columns.

At the site, connections are made in few seconds by injecting non-shrink grout into the Groutec’s cavity.

The project is expected to be completed by 2022.

The expansion project of the Lai King Building, established in 2001 at Princess Margaret Hospital in Hong Kong, aims to enhance ambulatory care services and ensure compliance with infection control and service standards in modern healthcare settings.

The project involves the demolition of the existing structure, construction of a new extension block, renovation and refurbishment of the existing building, construction of link bridges connecting the new extension block and the existing building, as well as external works and landscaping.

Dextra is actively involved in the site formation and foundation works, which commenced in August 2021. Our contribution includes supplying Astec GFRP (Glass Fiber Reinforced Polymer) soil nails with a diameter of 32 for temporary support during excavation. These soil nails are renowned for their lightweight composition, making them easier to handle and install. This characteristic significantly reduces labor requirements and construction time, thereby allowing for greater productivity on-site.

Furthermore, the GFRP material used in these soil nails exhibits high resistance to corrosion, distinguishing it from traditional steel soil nails. This attribute ensures the longevity and durability of the temporary support system, ultimately reducing the need for costly maintenance and replacements in the future.

The exceptional tensile strength of the GFRP soil nails plays a crucial role in effectively restraining the lateral displacement of the soil, thereby minimizing the risk of ground movement and potential collapse.

The construction works for the entire project are expected to be completed by 2026.
