A concrete headwall is a structure installed at the outlet of a drain or culvert that functions as a retaining wall to protection against erosion, or as a means to divert flow.
Precast concrete headwalls and wingwalls are a vital component of drainage culverts and bridge sections. Headwalls and wingwalls are designed to function together with the conduit to provide a functional and dependable permanent structure.
A drainage culvert outlet headwall helps to prevent erosion that affects the surrounding area, to lessen the possibility of flooding. Headwalls also help to prevent erosion around bridges, to protect structural integrity.
