Precast box culvert headwalls are the perfect alternative to in-situ inlet and outfall structures for the start and end of box culvert runs. Althon culvert headwall units can be factory with flap valves, penstocks, kee klamp handrails and a selection of gratings dependant on application.

Our box culvert headwall designs recess the inflow and outflow at the end of the box culvert into the slope to improve flow conditions, anchor the box culvert and prevent disjointing due to excessive velocities. For extremely large box culvert sections or we offer a header beam and wingwall system. We can also supply culvert headwalls with mammal shelves if required.
