Pipes and Custom Headwalls in Perth and Western Australia

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.

Installation

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.

Maintenance Of Headwalls

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.
