WORCA Housing Half-Tunnel Form
A modular steel formwork system designed for the housing industry’s repetitive module construction. It streamlines construction speed by casting all primary concrete elements (walls & slabs) simultaneously, utilizing a simple and repetitive process that eliminates the need for highly skilled workers. This translates to reduced time and labour costs, while ensuring a highly consistent construction schedule, precise concrete dimensions, and a superior concrete finish.
