Structural Drainage Systems

Box Culvert

Reinforced precast box culvert for high-load drainage and underpass systems.

The Precast Box Culvert is a reinforced concrete closed box section engineered for high-load drainage and underpass applications. Manufactured under controlled factory conditions, it delivers the consistent strength and dimensional accuracy that cast-in-place construction cannot match. Available with internal widths from 600 mm to 2500 mm, each unit is joined with a spigot-and-socket connection featuring a rubber-gasket groove and a mortar-filling groove, creating a sealed, watertight run. This makes the box culvert ideal for stormwater drains, road and rail underpasses, service ducts, and cattle crossings where heavy vehicular loading is expected. Precast manufacture allows rapid on-site assembly with minimal disruption, while the dense, reinforced concrete section provides excellent durability and a long, maintenance-free service life.

  • Heavy-load bearing design
  • Reinforced with high-tensile steel
  • Designed for quick onsite placement
  • Excellent hydraulic performance
  • Can be used as service ducts or utility crossings
