Precast Concrete Tunnel Segments

Precast Concrete Tunnel Segments


No tunnel vision, intelligent solutions!

Prefabricated concrete segments are used for liners in tunnel construction. The production of tunnel segments is demanding; requiring a great deal of planning, scheduling and punctuality as the tunnel boringmachine – TBM – cannot run out of segments halfway on its way through a mountain or under a river.

KRAFT CURING offers several curing solutions for the accelerated hardening of concrete segments, depending on carousel or static production style, space availability and project specifications for post curing and quality control documentation.
