Tunnel formwork Formkret

Product Overview
The Formkret automated formwork filling system is the result of a strategic partnership between Kern Tunneltechnik and Putzmeister to deliver concrete filling solutions for tunnel construction. The system automates hydrostatic filling of secondary concrete linings by using 2-way valves integrated into the formwork and a single delivery line that links sequential rows, reducing manual intervention and optimizing site operations.
