    "EMJ Plastics Limited were engaged to design, manufacture and deliver permanent formwork panels (Permadec) for a new road bridge in Newhaven, East Sussex. They were superb throughout the procurement, design and manufacturing stage. The Permadec system is extremely fast and easy to install especially when using the lifting frame to load out multiple panels at a time. The system seals really well requiring no additional protection when pouring the concrete deck above, even when working over a live railway. I would happily use this system and EMJ Plastics Ltd again."
