What is a headwall and Wingwall?
Headwalls and Wingwalls are produced to finish and secure the ends of pipe, box culverts and bridge sections. They are designed to function together with the conduit to provide a sound, functional and permanent structure.
What is the purpose of a culvert headwall?
Culvert headwalls are attached to the ends of a culvert to reduce erosion, inhibit seepage, retain the fill, improve the aesthetic and hydraulic characteristics, and make the ends structurally stable. Two basic types of headwalls are available. They are broadly classified as safety headwalls and non-safety headwalls.
What is a driveway headwall?
Headwall means rock, concrete, masonry, metal, timber, or other similar materials placed on the sides of an approach as support, to prevent erosion, or for decorative purposes.
What is a culvert Wingwall?
Overview. Wingwalls are headwalls that have vertical concrete slabs that extend at an angle from the pipe opening. They can be made with aprons or footings as needed, and offer superior bridge support and erosion control.
What is a concrete Endwall?
Headwall or Endwall– An integrated wall located at either end of drainage pipe or a stream crossing structure. A wall built at a pipe outlet is an endwall.
What is a concrete headwall?
The Headwall is a precast concrete structure with wings and a bottom to deflect the water away from the soil. Headwalls are used to provide support for bridges and roadways by anchoring the piping to prevent movement due to hydraulic and soil pressures and prevent soil erosion and scouring from turbulent stormwater.
What is a headwall in construction?

What is a headwall civil engineering?
A headwall is a wall, made of a variety of materials, often placed at the outfall of a drain or a culvert to serve as a retaining wall and protect fill from scour or undermining, increase hydraulic efficiency or divert the direction of flow.

What is a headwall construction?
Traditional headwall construction is stick-built, basic drywall with a millwork panel added overtop. Cutouts are made onsite. This style is quite labor-intensive, which means a large number of trades working in one space during installation.
