Tunnel Reinforcement

CHALLENGE: Corrosion of tunnel walls required new steel liner plates. Underground access was limited to only one side.

SOLUTION: BoxBolt® was selected for their unique advantage: Dependable steel-to-steel reinforcement for one-side-only installations

Success Factors:

- A customized , extra long BoxBolt® was engineered to meet challenging wall density requirements

- 61,000 BoxBolts® were installed to secure the tunnel structure
