Box Culverts

Precast Box Culverts are ideal for situations where depth or height restrictions demand wide, shallow conduits to handle required flows, as well as:

  • Installations where circular or elliptical concrete pipe cannot provide adequate flow capacity
  • As a superior substitute for cast-in-place box culverts, long-span metal arches, short bridges and multibarrel circular culverts or drains

Applications

Precast Box Culverts can be used for the following:

  • Highway culverts
  • Railroad culverts
  • Short-span highway bridges
  • Storm drains
  • Extension of existing box culverts
  • Livestock, pedestrian or golf cart undercrossings
  • Utility tunnels
  • Underground stormwater retention systems
  • Groundwater recharge systems
  • To replace existing open channels or ditches, enabling land to be used productively
  • Jacked or tunneled installations

Sizes

Precast Box Culverts are normally available in spans of 3 feet through 12 feet, with a variety of rises. Some markets produce spans to 20 feet. Contact your local Forterra representative for specifics.
