Transit Concrete Culvert Ends
In conjunction with NZTA, Humes has developed precast concrete headwalls for pipes running either parallel or perpendicular to the carriage way.
- Stormwater drainage
- Culverts
- Drainage
- Reinforced Concrete structure with concrete strength of 40Mpa
- Cast as one single unit which eliminates the issues associated with the jointing of old and new concrete, such as shrinkage cracks and integrity of the epoxy joint
- One size headwall accommodates pipe diameters from 225 to 450
- Soft spots for ease of installation
- The bottom of the headwall has a circular profile, which allows the debris to be washed away easily when compared to a flat bottom
- NZTA approved grating has been independently tested by Opus for its load bearing capacity
