Concrete Canvas Shelter, An Inflatable Concrete Building
The Concrete Canvas Shelter is a remarkable inflatable concrete building that lets military and civilian users erect a permanent building in one day. The key to the system is a new construction material, concrete canvas, a flexible cement-filled fabric that hardens when water is added. The building starts out collapsed in a bag for easy shipping. The building is then inflated on-site, a process that two untrained people can complete in less than an hour. Water is added and the building hardens into concrete. In 24 hours it is ready to use. The Concrete Canvas Shelter was created by UK-based Concrete Canvas Ltd.
