Sacrificial formwork, also referred to as permanent or stay-in-place formwork, remains in position after the concrete cures. It removes the need for stripping and reduces labour, time and manual handling on site.

Sacrificial formwork is used in basements, lift shafts, retaining walls, civil structures and multi-storey buildings. It is particularly effective in areas with limited access where removing conventional formwork is impractical.

Permanent formwork is designed for long-term durability. Once installed, it forms an integral barrier that resists water ingress, soil pressure and environmental wear, helping protect the concrete and extend its service life.

It depends on the application. Fibre cement is common, along with rigid polymers and galvanised steel. The right material will vary based on site conditions, structural loads and exposure to moisture or chemicals.

Yes. Several systems are engineered specifically for harsh environments, including coastal locations, wastewater plants and underground structures. These products are designed to withstand both chemical and physical stress.

Permanent formwork reduces labour requirements, minimises waste and eliminates the need for formwork removal. It also improves safety and efficiency, especially on high-rise or complex sites where access is limited.

No. Properly installed permanent formwork supports alignment during curing and provides added protection to the concrete surface, contributing to consistent and durable structural performance.

Allcon supplies a range of panel sizes, thicknesses and profiles suitable for retaining walls, core shafts and other structural applications. Contact our team for assistance selecting the most appropriate system for your project.
