Cross Connections from Foamrox

The Principle Behind the Solution

How It Works

Foamrox cross connections are built from lightweight, prefabricated modules that are easily installed between tunnel bores. The system provides a fireproof and smoke-free passage while ensuring easy access for operations and maintenance. Prefabricated elements make installation fast, space-saving, and ready for use without any post-work.

Installation of Cross Connections

Foamrox cross connections are delivered on pallets with all necessary materials and a simple installation manual. The elements are easily lifted into place using a standard electric lifting machine and require no post-work such as drying time or painting—unlike traditional concrete structures. Once the connection is installed, all technical equipment can be attached directly to the wall and ceiling elements, making the installation ready for use in a short amount of time.
