Concrete Canvas Shelters are rapidly deployable hardened shelters that require only water and air for construction. Patents have
Concrete Canvas Shelters (CCS) have two major advantages over conventional tented shelter:
Operational: CCS enable a hardened structure from day one of an operation. They provide much better environmental protection,
increased security and vastly improved medical capability.
Financial: CCS have a design life of over 10 years, whereas tents wear out rapidly and must then be replaced. CCS are a one stop solution, saving effort and cost over the lifetime of medium to long term operations.
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. CCS consist of a revolutionary cement based composite fabric (Concrete Cloth) bonded to the outer surface of a plastic inner which forms a Nissen-Hut shaped structure once inflated.
A 270sqft CCS can be deployed by 2 people in less than 1 hour and is ready to use in only 24 hours.
The compressive structure of CCS has been modelled to be covered with sand or earth (berming) to provide protection against small arms fire and shell fragments.
CCS concrete shells have good thermal properties. When buried they provide excellent insulation and a very large thermal mass.
CCS are far more durable than tenting with a minimum design life of 10 years.
The sealed plastic inner of a CCS, means it can be delivered sterile.
Concrete Cloth is a ceramic and will not burn. Each shelter is lined with a flame retardant fibre reinforced polyethylene inner with a B1 (DIN 4102-01 05/98) fire rating.
CCS can be fitted with a combined forced air / inflation unit and decontamination module to provide full spectrum CBRN protection.
The hard shell and lockable doors of a CCS provide a level of security not possible with soft skinned structures, protecting stores, equipment and personnel.
CCS provide all the benefits of a permanent structure without the associated cost and time delays.
Size Variants Concrete Canvas have developed two shelter variants, CCS25 and CCS54 (with 270sqf. and 580sqf. of floor space respectively).
CCS structures have been designed to maximize their internal usable space.
A standard CCS54 can accommodate up to 15 people according to Sphere Standards, Humanitarian and Disaster Response Charter.
For longer term operations, CCS54 will accommodate 8 standard cots with free standing mosquito nets. The technology can be scaled up to provide even larger structures.
Future product developments include shelters to be used for storage of vehicles and helicopters.
CCS structures are designed as part of a modular system; units can be easily linked together enabling the space to be tailored to the application. CCS are designed as generic structures with initial uses as accommodation, field offices and secure storage. Small openings for services can be cut or drilled in the Concrete Cloth shell. Larger openings for windows can be cut but require bolted frames to distribute the stress. CCS can be demolished using basic tools. The thin walled structure has a very low mass leaving little material for disposal.
