Sturdy connections for Dubai’s new metro
Dubai Light Rail Link, Dubai, United Arab Emirates
The line for Dubai’s new metro – the world’s longest driverless rapid transit system – will be comprised of 11,400 precast concrete elements. The adhesive used for connecting the separate elements has to meet high requirements: It has to exhibit consistently good processing properties in at times extreme climatic conditions. And, the joints have to withstand heavy vibrations intermittently caused by moving trains.

A new adhesive for solid connections
Experts from BASF mastered this challenge and developed the custom-formulated Concresive 1441 within only a few months. Thanks to the adhesive, the separate concrete parts behave like one single element. Because of this, impacting forces – vibrations for example – are dissipated and absorbed in a much better way.
Customized solutions for summer and winter
The BASF team designed two versions of the epoxy resin based adhesive on site: One for usage during the cooler winter months, and a summer version that is easy to process, without any segregation, during the hotter parts of the year. Concresive connects the concrete elements durably and prevents water or sand from penetrating the joints. During the construction process, the BASF experts supported the engineers and workers with application tests and trainings.
