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:
The PVC Wall Formwork System can replace nearly all types of vertical formwork used for walls and columns.
