Uses
Precast Concrete Box Culverts can function as a structure, a conduit or both!
They are recommended for applications where circular concrete pipe cannot
provide adequate flow capacity. Precast Boxes are a superior substitute for
cast-in-place box culverts, long-span metal arches, short bridges and multibarrel
circular culverts.
