Sacrificial formwork helps solve everyday site challenges such as delays, rework, and waste. Sacraform™ by Danterr is a high-quality stay-in-place formwork system that rethinks how concrete formwork is done. Once the concrete is poured, Sacraform™ remains in position, removing the need for stripping or dismantling. This smart design saves labour, reduces waste, and keeps projects on schedule, all while meeting Australia and New Zealand’s strict safety and quality standards.
What Is Sacrificial Formwork and How Does It Work?
Sacrificial formwork, also called stay-in-place formwork or permanent formwork, is a type of formwork that stays in the ground once concrete has been poured. Instead of removing the formwork like traditional concrete shutters, sacrificial formwork becomes part of the finished structure.
It helps support the concrete during pouring and curing, then remains in place to protect and strengthen the build. This simple idea makes a big difference. It saves time, reduces manual work, and means less waste on site, which is better for both the team and the environment.
What is Sacraform™
Sacraform™ is Danterr’s preformed sacrificial formwork system made from strong steel wire mesh with a layer of plastic on both sides. This gives it excellent strength and durability while keeping it light and easy to handle.
It’s built to make concrete work easier, faster, and safer. Sacraform™ is used under slabs, around footings, ground beams, cages, penetrations, and even as safety or privacy screens on site.

Why Choose Sacrificial Formwork Over Traditional Concrete Shutters?
Traditional concrete shutters have long been the standard for forming concrete structures, but they require significant labour, time, and material resources for installation and removal. Sacrificial formwork like Sacraform™ offers a more efficient alternative.
The Benefits of Using Stay-in-Place Formwork in Modern Construction
The shift towards stay-in-place formwork systems is driven by measurable, real-world benefits:
- Enhanced Safety – Reduced manual handling minimises injury risks on site.
- Labour Efficiency – Eliminates stripping and cleaning of reusable formwork.
- Cost Reduction – Lower labour and waste disposal costs over project duration.
- Structural Consistency – Ensures precision and uniformity in concrete pours.
- Sustainability – Supports green building objectives through reduced material use.
- Design Versatility – Adapts to various shapes, sizes, and structural applications.
Sacraform™ brings all these benefits together in one smart product, empowering Australian contractors to build faster, safer, and greener.
Project Highlights: Where Sacraform Makes a Difference
Sacraform™ has already been used successfully in one of the major infrastructure projects in Australia, proving its performance and versatility in the field.
The West Gate Tunnel Project
Sacraform™ was proudly used in the West Gate Tunnel Project, one of Victoria’s largest and most complex transport infrastructure developments valued at over $10 billion. This major project aims to ease congestion, improve travel times, and provide a vital alternative route to the West Gate Bridge.
Danterr was honoured to supply high-quality products including Sacraform™, to support construction efforts on this tunnel project.
Proven Performance and Positive Feedback:
During its trial run, Sacraform™ quickly gained attention across the industry, selling out twice in just a short period. It’s become a trusted choice for Tier 1, Tier 2, and Tier 3 contractors, with strong feedback from the field.
It’s so quick and easy, all the inspectors loved it and didn’t have a problem. We were planning to use it due to the amount of rain we’ve been having and if we didn’t get the concrete in today it would drain the water. It went in so quick we had concrete by 1pm. — Callum, MJ Baker Builds
The pile caps were successful, and the Sacraform Sacrificial Formwork along with other key accessories have been reordered since. — Tier 3 Contractor
