Concrete Canvas Shelters – Brilliant Shake-and-Bake Buildings


Concrete Canvas Shelters are fast-to-deploy, hard shelters that need only water and air for construction. The shelters are made of “concrete cloth”, a flexible material made from a mix of cloth fibres and concrete mix, with a PVC backing on the inside.


To erect the shelters, the inner liner is inflated via an electric fan. As the liner expands it lifts the concrete cloth into the Nissen hut shape, which is pegged out and the canvas is then hydrated with water or seawater. In 1 hour the structure is self supporting and in 24 hours it’s ready to use.

The shelters ship with lockable doors at each end and once they’ve been built they will last for at least 10 years. The shelters have good thermal properties, even better if they’re buried, and the outside is flameproof. The plastic lining inside can be delivered sterile so you’ve got an instant hospital and it can be supplied with a decontamination air supply for Chemical/Biological/Radiological and Nuclear use. They’re shipped sealed too and can be stored indefinitely until disaster calls.

There are two variants so far, the CCS25 which produces a 25m� structure from a 1,800kg kit, and the CCS54 which produces a 54m� shelter from a 3,100kg kit. Future developments include structures large enough to store vehicles and helicopters. You can also buy the concrete cloth in sheets for use building water reservoirs, instant hard surfaces and improved sandbag defences.

Concrete Canvas Shelters are rapidly deployable hardened shelters that require only water and air for construction. The 25sqm variant can be deployed by 2 people without any training in under an hour and is ready to use in only 24 hours. The key to CCS is the use of inflation to create a surface that is optimised for compressive loading. This allows thin walled concrete structures to be formed which are both robust and lightweight.
