Precast Box Culvert

A Precast Box Culvert is a reinforced concrete (RCC) structure designed to allow water to pass beneath roads, railways, embankments, or infrastructure corridors. Unlike cast-in-situ culverts, precast box culverts are manufactured off-site and installed quickly at the project location.

They are widely used in:

  • Stormwater drainage systems
  • Highway underpasses
  • Irrigation channels
  • Canal crossings
  • Railway infrastructure
  • Utility corridors

Precast box culverts offer faster installation, better quality control, and reduced on-site construction time.

600 x 600 x 600mm

Ideal for light to medium drainage applications in residential layouts, internal roads, and small infrastructure projects.

750 x 750 x 750mm

Designed for moderate stormwater discharge in urban developments, commercial complexes, and township infrastructure.

1200 x 1200 x 1200mm

Engineered for high-capacity water flow and heavy-duty infrastructure applications such as highways and industrial zones.
