Althon provides purpose-made header beams and wingwalls for box culverts to suit specific situations and applications.

Header beams

  • Extend the full width of the culvert
  • Secured with stainless steel dowels with high-strength, non-shrink grout
  • Straightforward beam or an “L” beam to withstand higher loading stresses

Wingwalls

  • Formed using L-shaped walls
  • Profiled to match surrounding ground
  • Range of loadings can be accommodated

The units are free standing, so can be adapted to any angle.
