Get an inside look at our revolutionary trenchless manhole rehabilitation system with our FLEXLINER!

The FLEXLINER is the perfect choice for construction sites with special on-site conditions and when several days of bypassing are not possible. 

Benefits of this system:

• Minimal disruption: no digging work, 100% trenchless
• Faster installation: reduces the overall downtime of the infrastructure being rehabilitated 
• Lower environmental impact: With less excavation and disruption, trenchless methods can have a lower impact on the environment than traditional open cut construction methods. Preservation of trees, landscapes and minimizing disruption to ecosystems are some of the environmental benefits.
