Headwalls and Wingwalls

Headwalls and Wingwalls are produced to finish and secure the ends of gravity pipe, box culverts and bridge sections.

They are designed to function together with the conduit to provide a sound, functional and permanent structure.

  • The conduit enters or exits finished grade
  • Flow must be channeled into or out of a conduit
  • The earth embankment surrounding the pipe must be retained
  • The exposed pipe ends pose a danger to traffic
  • Appearance of the pipe end is important

  • Free-standing headwalls
  • Precast aprons

Sizes

Every conduit size and shape has a corresponding Head- and Wingwall system available.
