Innovative Formwork Filling System brings concrete secondary lining into the 21st century

Thanks to its strategic partnership with leading engineering group Kern Tunneltechnik, Putzmeister now offers an innovative formwork filling system, Formkret.

Regulated by a set of two-way valves integrated into the formwork structure and connected by a single delivery line that links the entire system in sequential rows, this latest innovation helps to reduce the need for manual work, enhancing work site safety and speeding up the overall process. Once a manual, labour-intensive process, the application of concrete secondary linings in tunnels has been brought into the 21st  century, thanks to Formkret.

With this latest offering, Putzmeister positions itself as a one-stop shop for all concrete related applications in tunnelling, further cementing its market leadership.
