Underground metro networks are transforming the way people move as cities become increasingly densely populated and urban mobility becomes more crucial. These large-scale infrastructure projects require precise engineering and reliable partners with a proven track record of technical excellence and consistent quality. Dextra Group is one such partner, trusted by designers, contractors, and fabricators worldwide for complex subterranean operations and over 20,000 major projects.

We have established ourselves as a global leader in reinforced concrete technology and engineered systems, building on a tradition of providing innovative construction solutions since 1983. Our engagement in some of the world's most challenging metro projects reflects the breadth of our technical knowledge and ability to tailor solutions to each stage of construction.

Tailored solutions for every metro challenge

Each stretch of metro construction brings its own set of technological obstacles. We offer a comprehensive array of solutions that are optimised for safety, speed, and dependability throughout the project lifecycle.

Coupler systems for reinforcement continuity

Coupler systems for reinforcing continuity are critical in ensuring structural strength, particularly in high-load areas such as metro stations and tunnels. Dextra offers a wide range of mechanical splicing solutions, including Bartec, Rolltec, and Griptec, for connecting rebars in structural elements such as columns, shear walls, rafts, slabs, and diaphragm walls. These systems are commonly used as structural connections for station boxes, tunnel segments, and base slabs.
