Box culverts are rectangular four-sided concrete structures used in managing and storing storm water. They can also be used where natural water sources need to circumvent an obstruction, such as a roadway that is built over a stream. They have a wide variety of applications including in underpasses, service tunnels, subways, and bridges.
Monolithic, split, and watertight styles are available. Precast box culverts are very strong and can be made in a variety of sizes to fit your needs.
Our manholes are manufactured to ASTM-C478 standards and accept pipe to manhole connectors to provide a sealed manhole system. Manholes are available with inverts, risers, cones, access hatches and steps.
