Box culverts are precast concrete structures designed for use in civil engineering and construction applications including stormwater management, underpasses, and service tunnels. Manufactured in a variety of internal sizes and profiles, these culverts provide a smooth internal finish to optimise water flow and are resistant to corrosion. They require minimal maintenance and meet current design life requirements for buried infrastructure.
