When forming the slab, work is completely carried out from a safe position below; the panels are simply hooked in and then pivoted upwards.

DUO Formwork

Efficiency & Versatility

The intuitive and quick application enables crane-free handling, while versatile and lightweight components reduce transport requirements.

The latest panel formwork system in our product portfolio is made from technopolymers, making it 100% recyclable. With no component weighing more than 25kg, DUO can be manoeuvred around construction sites with ease. Optimisation is a key benefit of the system’s design, as it can be used to form walls, columns and slabs with reduced tooling requirements.

A sustainable option for any construction project, the formwork system reduces the output of waste as it is reused in the production of new panels and components.

    “DUO works in perfect harmony with the experimental concrete mixes we are using in that both reduce labour and material costs, reduce the project’s carbon footprint and are definitive steps forward in construction methodology.”
