The universal lightweight formwork for walls, columns and slabs

DUO System Formwork

One lightweight formwork system for walls, foundations, columns and slabs

DUO is a formwork revolution. Lightweight yet strong, durable yet versatile. Thanks to its innovative technopolymer material, no component part weighs more than 25kg.

This lightweight handset system is easy to manouver on-site, freeing up the crane, and lowering the cost of transportation. The formlining can be changed easily and quickly with no need for special tools or skills to extend the life of your panels. The system can be used for walls or columns, and is also designed for slabs - ensuring high utilisation of your asset across many applications on site.

DUO is also sustainable - all component parts are 100% recyclable with the materials at the end of their life milled down to produce new panels and component parts.
