In 1985, when Super Excavator expanded from underground utilities into the tunneling market, the work mainly involved hand mined tunnels. In the 1990s, the company entered large scale TBM (Tunnel Boring Machine) projects. Since then, it has gained tremendous experience and a solid reputation in both soft ground and rock tunneling.
Our team of experts has successfully completed tunnels that stretch from 4 feet up to 23 feet in diameter. We offer tunnel lining applications including jacking pipe, pre-cast segmental lining, as well as ribs and lagging with reinforced concrete pipe lining grouted in place.
Super Excavators found success and new challenges in this market and looks forward to continued success in this highly specialized area of construction.
Tunneling provides a host of advantages:
- Limiting surface disturbances
- Reduced costs of utility and facility relocations
- Environmental considerations
