THE SITUATION

The Swiss Lock Anchor has been a household name in tunnel construction for more than 40 years and is specified by the Swiss Federal Office of Road Construction (ASTRA) in the Technical Manual Tunnel/Geotechnology as a proven system for anchoring suspended tunnel decks and fire hatches, among other things.

ABOUT THE SWISS LOCK

The Swiss Lock is a wedge-free steel anchor, developed and patented by B+BTec, for the most critical applications.

CORE DRILLING SYSTEMS

Because every tunnel configuration is different, B+BTec designs and manufactures project-specific core drilling systems to carry out the drilling operations for installing the Swiss Lock Anchors as quickly and efficiently as possible.
