Quick Assembly Concrete Cloth Shelters Last 10 Yrs
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. _redferret
These shelters can also be buried underground for even greater protection from the elements. The 10 year lifetime is a minimum projection.
