Retractable Tunnel for Midwest Formwork

Stuart Canvas has recently completed a retractable tunnel for Midwest Formwork in Buckinghamshire. The company creates high quality reinforced concrete formwork and had a requirement to protect outdoor manufacturing equipment.  The large equipment needed to be able to remain operational whilst being protected from the elements. Our specialist team advised that a retractable tunnel would be the best solution as it allows the machinery to be covered quickly, should the weather change and offer a solution for the machinery underneath to still operate.

Due to the large scale of the manufacturing equipment, the tunnel was placed on anti-lift guide tracks to provide support and ease of manoeuvrability.  Stuart Canvas manufactured the tunnel using the kedar system. This system consists of individual PVC panels, 1.1m wide which are produced to the exact width of each pentagraph centre of the tunnel frame. Each panel is sewn with the keder on both sides and high frequency welded to create a waterproof structure.   This allowed Stuart Canvas to create a tunnel that was 16 metres long and over 11 metres in width to provide complete coverage.  Mesh panels were also built into the opening ends of the tunnel to allow wind to flow easily through the tunnel and to provide ventilation.

Whether large or small, fixed or retractable, Stuart Canvas can offer a temporary building solution for your needs and advise on how to create the best additional workspace both internally or externally. Our Tunnels can be produced as mobile or static spaces and can be designed to be easily dismantled and assembled should they need to be relocated in the future.

Founded in 1977 Midwest Formwork is one of the most successful and respected reinforced concrete formworks leaders in the construction industry. To find out more about Midwest Formwork, please visit their website:
