January 25, 2018 0 Comment

Box culverts are gaining in popularity across the country and we’re getting more and more questions on how to seal box culverts properly.

And it’s not just precast producers asking about these options, but contractors in the field and engineers responsible for designing and using box culverts in a variety of applications.

Some of the more common applications include:

  • Underpasses
  • Tunnels
  • Stream culverts
  • Storm water storage
  • Subways
  • Material handling

They are also available in a wide-variety of standard sizes as well as specific designs meeting the features and standards of almost any project.
