Headwalls
Headwalls
Civilcast Headwalls are precast concrete sloping headwalls designed to protect stormwater pipes and prevent erosion around culverts. They are manufactured in a standard range to suit pipe diameters from 225mm up to 900mm, with each headwall size fitting a range of standard pipe sizes, and precast construction keeps installation straightforward compared with in-situ alternatives. Civilcast describes itself as a leading precast concrete headwall manufacturer and supplier across the eastern seaboard of Australia. Headwalls are compatible with Civilcast Headwall Security Grates (heavy-duty, hot-dipped galvanised steel grates designed to restrict unauthorised access to culverts and drainage outlets) for projects where public access needs to be controlled.
Features
Civilcast Headwalls, part of Civilcast’s Precast Concrete range, are precast to a standard range of sizes spanning 225mm to 900mm pipe diameters, with each size fitting more than one standard pipe size. Precast construction keeps installation simpler than an in-situ pour, and compatibility with Headwall Security Grates extends the range to projects needing controlled access.

Benefits
Headwalls earn their place on a stormwater drainage job mainly by reducing two costs: erosion repair after heavy rainfall, and on-site labour during installation — see Civilcast’s headwalls guide for the full picture. Precast construction means crews spend less time at the pipe outlet and more time on the rest of the stormwater installation.
- Reduces the likelihood of costly erosion repairs around pipe outlets after heavy rainfall events
- Lower on-site labour requirements free up crew time for other parts of the stormwater installation
Applications
Headwalls are typically installed wherever a stormwater pipe outlet needs erosion protection: embankments and subdivisions, parks and landscaped areas, and stormwater drainage running under driveways. Where public access to the culvert needs to be restricted, they’re paired with Headwall Security Grates to control entry at the same location.
- Embankments and subdivisions
- Parks and landscaped areas
- Stormwater drainage and driveways

FAQ's
225mm up to 900mm in standard sizes. For pipe diameters outside that range, check with Civilcast before specifying, since a custom headwall may be needed.
