Concrete Canvas Shelter - Just Add Water


Concrete Canvas Shelters (CCS)

Rapidly deployable hardened shelters that require only water and air for construction. Operational and financial advantages over conventional tented shelters and operational on the first day. The concrete shell offers better security and are environmentally friendly. The concrete shelter boasts a 10 years of design life. Savings on effort and cost over the lifetime of medium to long term operations. Can be deployed in military bases and when back filled the shelter is blast proof and flame proof. Concrete Shelters have been successfully deployed as field clinics and storage depots.

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.

CSS Key Facts


A 270sqft CCS can be deployed by 2 people in less than 1 hour and is ready to use in only 24 hours.

Force Protection

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.

Fire proof

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.

CBRN protection

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.
