We offer a complimentary obligation-free estimating service for the waterproof warranty system (which combines Dincel walls and the Dincel resin-injected waterstop). Please feel free to email me the architectual and/or structural plans for a quote.
Structural certification by the University of New South Wales
In regard to structural design (including the topic of Fire Resistance Periods), Dincel Wall complies with the Deemed-to-Satisfy (DTS) provisions of the BCA, being compliant with AS 3600. The relevant DTS provisions have been certified by the University of New South Wales (click here for link) following review of the relevant Dincel manuals. The letter of certification can be seen on page 2 of this report. Therefore, in regard to the role and responsibility of the project structural engineer, compliance is in accordance with the DTS pathway.

Concrete mix specifications
This is the direct link to the construction manual - click here for link, where Section F.12.1 communicates information for concrete mix specifications.
In our construction manual, we communicate 2 options to achieve good compacted concrete:
· Use high slump conventional concrete with a minimum slump of 180mm at the point of discharge (i.e. at the pump) + vibrate the concrete adequately. Considering that concrete suppliers typically work to a 40mm slump tolerance, in our construction manual we highlight that it would be practical to therefore work to a minimum nominal slump of 220mm (this way, provided that the concrete arrives to site within specifications, you would achieve the minimum 180mm slump on-site which we recommend).
- Use Self-Compacting Concrete (which doesn’t require vibrators for compaction purposes) with 680mm spread. This is a direct link to the testing video showing void free (and segregation free) Dincel concrete walls - click here for link
Practical spacing of reinforcement
Vertical Reinforcement
- 110mm/155mm/200mm Profile, the distance between where the main profiles snap/clip to each other is 333mm. Therefore, a practical spacing for the vertical reinforcement bars would be at 333mm centres. In this case (if the vertical bars were spaced at 333mm centres), the person who is placing the vertical reinforcement bars into the Dincel formwork shells on-site simply needs to understand that they have to place a vertical bar (centrally, or at one or both faces) per main profile.
- 275mm Profile, the distance between where the main profiles snap/clip to each other is 275mm. Therefore, a practical spacing for the vertical reinforcement bars would be at 275mm centres. In this case (if the vertical bars were spaced at 275mm centres), the person who is placing the vertical reinforcement bars into the Dincel formwork shells on-site simply needs to understand that they have to place a vertical bar (centrally, or at one or both faces) per main profile.
Horizontal reinforcement
- If horizontal reinforcement is required, then horizontal bar reinforcement should be at a spacing at an increment of 150mm (for example, 300mm centres), as the web holes are at 150mm centres.
Eliminating the requirement for horizontal reinforcement for crack control

Chemical resistance tests
The Dincel material has been tested against 4 different types of acids and successfully tested for 1406 days within Diesel oil (please find the reports attached).
- Nitric Acid (69% concentration)
- Hydrochloric Acid (35% concentration)
- Sulphuric Acid (98% concentration)
- Phosphoric Acid (85% concentration)
