Box Culverts & Tunnels

2000 Concrete specializes in cut and cover tunnel construction. Both drainage tunnels (called box culverts) and utility tunnels sometimes require special construction techniques - especially when these underground structures are built in congested and/or urban areas. These measures may include utility location, utility support, support-of excavation, waterproofing, dewatering, and special formwork systems. Please allow 2000 Concrete to use our knowledge to solve your constructability problems.

In addition to concrete construction, we offer the following additional scope items in connection with tunnels and box culverts upon request:

  • Special forming techniques for tunnels
