Dallcon manufactures customised headwalls and pipes applicable for water drainage projects associated with roads, bridges, railways and mine sites. They minimise soil erosion and scour at outfall connections where the water pressure is high and turbulent. Our headwalls help improve water flow while preventing soil from sloughing into unintended water bodies. The aperture within the headwall comes in different sizes and can be moulded to fit your specific design details.
Dallcon’s precast concrete headwalls can accommodate all sizes of clay, concrete or plastic pipelines. At Dallcon, our expert design team can custom build retainer headwalls and pipelines for your specific needs. Our factory produced items eliminates the need for on-site construction. Your fast-paced development projects will never be delayed with our customisable solutions.
Available to suit pipe diameters from 225mm to 2550mm and box culverts from 300 x 150mm to 3000mm x 2400mm. We can also custom manufacture multi-segment and cell headwalls to suit any application.

Dallcon manufactures a wide range of standard and custom precast headwalls for drainage outfall connections into open areas. These durable concrete products are capable of effectively supporting stormwater and drainage management systems in roadways, pedestrian bridges, stormwater management, driveway crossovers etc.
Dallcon’s precast concrete headwalls also help preserve the surrounding environment by minimising erosion at the outfall connection. The fast installation of precast concrete headwalls is a distinct advantage over on-site shuttering. They also provide the most efficient solution when the site is difficult to access, and when time is limited.
Our pipes and custom headwalls are available to suit pipe diameters from 225mm to 2550mm and box culverts from 300mm x 150mm to 3000mm x 2400mm. We can also custom manufacture multi-segment and cell headwalls to suit any application.
Precast concrete headwalls are best for not only quick and safe installation but also efficiency. All Dallcon’s pipes and custom headwalls are engineer-approved and go through rigorous quality and safety inspections before being dispatched to the site. Some of the features of the products include
Installation of Dallcon precast pipes and custom headwalls is fast and efficient. It not only reduces the need to pour concrete near the watercourse but also requires a smaller team to assemble. All you need is the correct site preparation and the right equipment. All the headwalls we produce are constructed with the proper lifting points so that they can be lifted and fitted on-site with ease.
Dallcon can provide detailed installation instruction for all of our pipes and custom headwalls on request.
Only annual routine cleaning with a power washer and possibly some mild detergent to any exposed surfaces may be necessary for the maintenance of the exposed concrete surface. But since all sites are unique, the environmental impact of cleaning should be taken into consideration. If the ecological conditions prevent detergent, using clean water and a power brush for cleaning should do the job.
Dallcon recommends a replacement (not repair) if there is profound damage to the structure of any concrete components. However, minor damages can be repaired with an epoxy compound.
The preferred method to dispose of any precast concrete components is by recycling the material by crushing and grading. For small quantity concrete, however, disposal in conventional landfill is acceptable as it is a cost-effective option.
