In May 2021, Australian Precast Solutions (APS) established a precast manufacturing facility in the south-eastern Melbourne suburb of Seaford, to facilitate the precast supply to the nearby level crossing removal project.
Being a road-rail grade separation project (level crossing removals) there were tight timeframe for the facility establishment, production and for delivery to meet the pre-booked rail occupation dates.
Within 1 month the facility was mobilised, established and resourced to cast over 430m3 of coloured and grey concrete – this included 6 pedestrian bridge pier segments (>30 tonne each) and over 180 building panels and barrier panels for 3 new railway stations – all cast, finished and delivered within 4 months.
The building and barrier panels for the 3 new railway stations included architectural features such as the use of coloured concrete, a recessed pattern, and a combination of smooth and sand blasted surface finishes. With the assistance of Actech, the use of Hebaunal was trialled to replace the need for sandblasting.
Programme was achieved and all panels delivered and installed during the rail occupation timetable. The use of Hebaunal allowed for faster turnaround time from casting to delivery and enabled the “sand blast finish” to be replicated in-house without the need for subcontractors or specialised equipment.
One of the many benefits of using CSE Pro (Hebaunal) is the consistent finish that is achieved time and time again. Precasters are able to manufacture multiple units with the confidence that once erected on site there will be no visible difference in exposure depths from unit to unit, eliminating the need for costly and messy site “touch ups”.
CSE Pro (Hebaunal) offers a range of exposure depths ranging from 0.5mm through to 7mm, catering for all Architectural requirements from micro exposure to coarse exposure.
Because the exposure depth is chemically controlled, once the precast element is lifted from the casting bed & ready for water blasting, it is a simple task that can be carried out with ease & confidence and no experience is required.
If the precast element is cast on a Friday, the element can remain on the casting bed over the weekend and the need to water blast can wait until the following Monday, so suitable for weekend production which is a real added bonus when dealing with retarders and unlike other retarders there is no need for scrubbing, waterblast only.
CSE Pro (Hebaunal) is an easy and economical way to achieve that Architectural expensive exposed aggregate finish.
Architectural Exposed Aggregate finishes are usually achieved by use of sandblasting, retarders & to a lesser extent acid etching.
CSE Pro (Hebaunal) is a far better alternative to sandblasting when trying to achieve that architectural exposed aggregate look as it will achieve a far more consistent finish than sandblasting as it is chemically controlled as opposed to operator controlled with sandblasting.
CSE Pro (Hebaunal) offers a range of exposure depths ranging from 0.5mm through to 7mm, catering for all Architectural requirements from micro exposure to coarse exposure with absolute consistency and confidence, which is something that cannot be quantified when sandblasting.
