PVC Wall Formwork System
The PVC Wall Formwork System is an extruded Polyvinyl Chloride (PVC) permanent wall formwork system. It consists of a number of outer edges that interlock via central link panels; these join the sides prior to the concrete core filling. Once filled it serves as a structural element allowing the builder to reduce the overall construction time and cost of the project. Designed and produced for Australian conditions it is a sacrificial formwork for concrete walls, as it remains in place for the life of the structure.
The PVC Wall Formwork System is:
- Lightweight
- Easier to install than brick or concrete walls
- Usable without cranes or other lifting equipment
- Speedier in construction and with wall thickness reductions that generate savings
- Installed in less time and with less required labour
- Less tool and equipment intensive, reducing safety risks and associated costs
- A sophisticated engineering technique that uses less horizontal reinforcing, footing sizes and suspended slab thicknesses
The PVC Wall Formwork System can replace nearly all types of vertical formwork used for walls and columns. This makes it suitable for specialised facilities such as hotels, hospital and aged care, as well as civil constructions. Its versatility means it can be used for a number of applications including: concrete walls, lift shafts and stairwells, shear walls, boundary walls, basement walls, retention tanks and civil structure walls amongst others.
